cold air intake on 5.7L Hemi

[littleJohnnyfromNJ]

has anyone had any experience with the benefits of installing a cold air intake on the charger (or any ohter care for that matter)? I am a novice at all of this but learning... would welcome the thought of adding more power to the engine.... would imagine this would best be done at the same time as adding a new exhaust??? Any advice would be appreciated.... is a cold air intake a mod that a novice can do????

[Racer X]

I just added a K&N Aircharger to my baby. I did the job myself and have little or no experience. It took me about two hours to complete the job. It was not hard to remove the old intake and place the new in its place. However, there were so steps on the K&N that were a little difficult like mount the heat shield and some other parts. No big deal.

As far as the benefits I can tell you that it has a little more power and it sounds bad a$$ when you hit the gas. I have also heard that you can see a slight improvement in gas mileage as well. Not sure if this is true or not. I just installed mine yesterday. Oh, did I mention that it sounds bad a$$.

Overall installation, I would try it it again.

[littleJohnnyfromNJ]

and how much did it run you $$$$???

by they way... does it sound bad a$$??? ;-)

[Racer X]

215. Oh, did I mention that it sounds bad a$$.

[hustlemeen]

i thought you couldnt have the aftermarket cai on the 5.7 because of the feature that turns off four of the cylinders while cruising and all of that extra air blowing in would mess up the engine

[NiteHawk]

that's nonsense, the MDS system and the motor in general will not be hurt by a cold air intake. the MDS system may shut down 4 of 8 cylinders, but think about it this way...

Stock intake takes in X amount of air...MDS turns on and kills 4cyl...

Aftermarket intake takes in Y amount of air, barely over X...MDS still turns on and kills 4cyl...

does that help?


basically i'm just trying to say that 1, CAI's are not in my opinion worth it for the charger, and 2, that they will not cause any harm what so ever to your charger

[BOYINBLUE]

Ok, I am trying to understand this stuff because I am def a noob. Would I get anything from the K & N drop in filter alone. it seems the only benefit you get from the air intake is when you have the exhaust changed. any info would help

[heinee]

One of the board members did a comparison of 3 different CAI systems on a dyno, using the stock intake as a baseline. Rather in depth and a lot of reading, however the information provided will most likely cause some head scratching..it certainly is over here...

[maximus]

Just added the K&N Kit and love the sound and based on what K&N states it added 24+ horses. The intstallation was simple as well being I never had done one before. I am having trouble getting my pictures to upload so I can't show you the outcome. However, it looks great as well!

[GoDaddy]

i want some pics man....interested in seeing some pics of your seats on the inside based on your sig. also.

[littleJohnnyfromNJ]

to those of you that installed the CAI (it sounds bad A$$).... is it loud all of the time or only under heavy acceleration? I installed flowmaster mufflers (super 40's) and Magnaflow resonators today - they sound nice.... any louder at highway speeds would be distracting as it is my every day car and I need to talk on the cell phone in that car.... will the CAI be even MORE distracting for me? Or is it loud only at lower RPMs???? help?

[littleJohnnyfromNJ]

and yet another question to you all... Chrysler Corporate advised me against the CAI today saying it could, possibly, maybe void my warranty on the engine and to proceed at my own risk even with a MOPAR part in stalled by my dealer! When the rubber hits the road, so to speak, what could possibly happen to my car from installing a CAI?

[GoDaddy]

that to me doesn't make any sense man, i am not saying anything bad about your post, but the fact that the dealership will install the cai (mopar at that) and say they may not help you out on warranty.....that is crazy to me.... i mean if they install it why wouldn't they take care of you....you ARE spending more money at the dealership...they are making more money off of you for part and the labor...common, give me a break (no you littlejohnny - your dealership)! that would kind of irk me a little (can you tell?)

as far as sound still waiting to get mine...dying to get it actually. and i have never heard anything bad about the cai on any car and i live in Louisiana where it always rains and guys drive them around with no problems....have read about the oil getting in engines from some guys on www.lxforums.com but it seems if you put to much oil on the filter you kind of deserve it. i am doing it, just don't have the cash for a few weeks to do it.

[AZCHARGER]

IT WILL NOT VOID WARRANTIES!!!!!

BTW, I just bought one and paied $199 shipped for it! :grin:

[littleJohnnyfromNJ]

so..... how do you feel, bigDaddy, and by the way.... is BigDaddy your name from ole' Bourbon Street's "place" by the same name???? hmmmmm???????? :wink:

i hear ya loud and clear - - - it miffed me too... I mean, install an aftermarket part manufactured by someone else and I can see, but the DEALER installing what is basically a "FACTORY" item? it should not even be questionned... and here's even more... the dealer and Chrysler both deny having a MOPAR CAI for the car.... idiots....

I'm dying to hear back from anyone with regard to the sound of the CAI.... I am not thrilled with the sound of my new Flowmaster Exhausts with Magnaflow Resonators.... it;s a lot better but there is a certain deep bass that is missing... am hoping that if I install the CAI that I can reap all of the performance benefits as well as the sound benefits without making it too obnoxious inside the car... are my expectations too high here???

I would also be eager to hear what problems (other than oil) may occour... BTW, if oil from the CAI gets into the engine, what happens???

[bstowers]

to those of you that installed the CAI (it sounds bad A$$).... is it loud all of the time or only under heavy acceleration?

You only hear it under hard acceleration.

For those that haven't heard it, I put up a short clip from my morning commute (http://bstowers.mesanetworks.net/video/moparcai.wmv). In the interests of my transfer quota, I'd appreciate it if you guys could save that to a file locally if you think you'll listen to it more than once.

[ANTMAG06]

That does sound good bstowers...Thanks for the clip. I will get my Mopar CAI today I hope and my Zoomers exhaust is in shipping now. I can't wait.

[ANTMAG06]

WWWWWWWWWOOOOOOOOOWWWWWWWWEEEEEEEEEEE!!!!!!!!!!!!! !!
Let me tell you guys it only took me about 35 min. to install the Mopar CAI and it unleashed so much HP it may just be a little around 10 to 15 I would think without dyno. But man I took it down the road just after I was done and ZIPEEE it flew. I have installed K&N CAI in the past on a 97 Z28 and a 2003 Mustang GT and never did I feel this much HP increase from just a CAI. And the sound, the sound clip from bstowers sounds good but let me tell you another thing try it yourself it sounds even better. I just got to say I am so happy with it and my Zoomers will go in on Tuesday.

[littleJohnnyfromNJ]

so the sound is ONLY under HARD acceleration???? I'm tryign to balance the nice growl of a muscle car with the refined interior of a Mercedes.... actually, I want it to sound mean enough but I want to be abel to talk on the cell phone still while cruising.... i ordered mine today for $259 (K&N) fro mMartel Bros with free shipping.... Auto Zone was $339 for the same thing...

[NECharger]

After reading the thread Heinee referenced, I doubt you unleashed any HP.
Maybe the noise is making it feel faster.

Aw, dude don't crash his party..... :no: It could have gotten 10 hp won't know now without a before and after dyno. I bet it sounds BAD A$$ ANTMAG06 want one bad but I have to wait till finances are in order and plus Christmas is around the corner....I know what's on my Santa's list

[Thunderkiss]

I installed the Mopar CAI. Drove it a lil but just the sound difference was noticable.

Hopefully when the computer sees it more, there will be a bit of a change.

I can't see any noticable change on any mod until the code's broke and we can tune it ( :confused: Maybe headers).

[HEMIRT]

if its anything like my mustang was, the computer will take back any power that was added...until a reflash/tune

[maximus]

i want some pics man....interested in seeing some pics of your seats on the inside based on your sig. also.



A couple of pictures are in the photo gallery. Take a look. More pics coming...

[maximus]

You may want to visit the KandN website and see the actual dyno readings for the KandN kit. I am not much of a motor guy but going from a 93 Dodge Shadow to the Charger it all feels great. :)

[HEMIRT]

the dyno sheet on k and n's site was pulled in 3rd gear, and it was on a magnum

[GoDaddy]

guys are doing great dynos with the cai, aftermarket exhaust and the headers.....as a combination you can't fight the fact that the car will respond...guys are dynoing around 35 to 45 hp rwhp. so i think the gains are there but not as much as possible with all 3. and hey, if it sounds faster it has to be faster...lol that's my theory and i am sticking with it....mopar cai in a few weeks...can't wait!!!

[ANTMAG06]

well all I know is if I can get up to a higher speed faster somthing has changed. There is a fork in my road and I used to only be able to get up to about 70mph before having to brake to go around the corner. Today after the CAI install I got up to 80mph way before I had to brake and I would have pushed it to go faster but the sheriff that lives down the road don't take nice to people flying by his house.

I know from experience NC cops don't play was doing 70 in a 55 on RT13 in Gates county and the SOB took me to jail and charged with reckless driving luckly I got the charged reduced and the judge let go with a "prayer of judgement" if no infraction in 1 year not reported to Va DMV.

This is just a little back woods state road. The Sheriff does not care if you do it a couple of times he knows we are just testing but to fast or to many times he will come out and get ya. Anyway I hope that after my Zoomers go in on Tuesday I will get a little more out of her. I will let you all know.

[Ron Mexico]

New to the board and looking forward to getting my new Charger.
After reaeding the thread on LXforums and so many others it seems that there is no power increase with a CAI, yet so many here have claimed that it does work. I myself am skeptical... Is it just denial that an OEM part was as good as an aftermarket? Or do all the people that claim it does raise HP work for K&N... I am just looking for the real scoop. Has this come to a conclusion?

Unbelievable, not only does it sound cool but looks soooo cool.

I'm thinking about having the engine cover painted to match it :rockon:

The consensus seems to be in my understanding that it will benefit horsepower but only after the computer code is cracked so that we can dyno the engine to match the mods.

If anyone disagrees with me please feel free to correct me :happy:

Well I will answer this one first...Do not work for K&N.
The CAI that I installed was the MOPAR CAI...I do not have proof but anything you do to your engine to make it work more efficient will let out a little more HP. The only reason I have no proof is because the nearest dyno that I know of is about 3 hours away in Releigh. Other than that all you can go by is testimonials about the experience and the new feel of the car with just a new CAI. This is all I can offer....

...Welcome to the forums.

[Ron Mexico]

Thanks for the welcome, I guess this topic will be on hold for a little while longer. But the MOPAR would look really cool in a blue Charger :rockon:

[GoDaddy]

dirtyom,

give me more info on painting the engine cover to match...what are you thinking about doing? i want to paint my engine cover bad, but i am afraid to do it myself. are you going to do it, there is a great how to over at www.lxforums.com or pay a shop to do it for you? give me info...more info....lol you have my curiousity kicking in hard.

[ANTMAG06]

Thanks for the welcome, I guess this topic will be on hold for a little while longer. But the MOPAR would look really cool in a blue Charger :rockon:

Yea the blue filter does look good and matches good with the Magnesium also. but I got it because I am installing a Cat-Back from Zoomers. Need more air in to get more air out.

[chargershed]

CAI's may improve throttle response, but will add little in the way of actual h.p.... the 5.7's main weakness is it's exhaust manifolds and smallish valves...Big gains can be had by changing the cam, I've seen a dyno test(in person) where a cam swap netted about 65 horses to the wheels, add the headers, the CAI and the free-flow exhaust and at least 120 h.p. to the wheels can be yours...without ever touching the PCM! then add some bigger valves, and voila! a SRT killer...the 6.1 has even more potential, with "special versions" running around with 650 h.p. at test facilities!

[GoDaddy]

mmmmmm.....so someone has had success with the cams...from what i have read and heard no one has been very successful with the cam change out in the magnum/300c/charger....how much are we talking about for a cam change by the way? another question the 65 hp with a cam is the highperformance cam right? how realistic is that as a daily driver?

[chargershed]

The cam was a mystery grind that was being beta tested ( I can't reveal the maker at this time) HAD A LUMPY IDLE, but did not cause the check engine light to go on :) the car was at 287 rwhp before the cam 353 rwhp after... no word on emissions compatability or long term use at this point...

[GoDaddy]

by lumpy are you saying it would act like it was going to cut off? damn though those are some nice numbers....are they working that out or is that part of the give and take of this mod? i need answers man!!! lol don't care about emissions in louisiana but the long term use is a definite question. keep us posted and thanks for the info

[GoofyGuy]

I want a cam with a big idle sound that with some flowmasters or magnaflows would be so nice.

This has been quite an education for me, this was cam #1 and now the fine tuning will begin, lumpy means that 95% of the people out there would think there was something wrong with the car...untill they put their foot in it :)

[CO-Charger]

... lumpy means that 95% of the people out there would think there was something wrong with the car...untill they put their foot in it...In a textual medium such as this, a normal idle could be "expressed" as:
Thump-thump-thump-thump-thump-thump...
It has a regular rythm and sounds like an engine running at idle.

However, a lumpy idle (due to high lift, long duration cams) have an entirely different sound when running at idle. Sort of like this:

Thumpity-thump-thump-thumpity-thump-thumpity-thump...
There is not a "normal" regular rythm to the sound. Some who are not car buffs would hear that and would certainly claim that the car was out of timing or fuel starved. But give an engine with one of those cams in them a slight goose in the throttle, look out, they come to life and fast!

[littleJohnnyfromNJ]

K&N CAI has arrived today... hope to install tomorrow.... will keep you all posted... I'm so excited!!!

[GoofyGuy]

a lopy cam would have such a bad ass sound to it with this motor and its large ohv setup and a nice exhaust. Anyone have a good cam yet?

[GoDaddy]

ok i gotcha you guys...i have never heard that term used before but i am on it now...so it comes off as the bad a$$ 70 type muscle cars. ok i am in...where do i sign up for a cam and how much?

littlejohn you have to post pics and clips or don't come back!!! lmao i am feeling it for you - i am dying to get my mopar cai in.

[littleJohnnyfromNJ]

OK... got the CAI from K&N... I did the FIPK Fuel Injection Performance Kit and not the Typhoon... anyway... it was supposed to be easy, and I guess in the grand scheme of things it was, but it was indeed the project from HELL!!!.... first, the tube had no hole for me to insert the air temp sensor. So, I foudn this out half way through installation aslt night. Cust svc closed so I had to take it all out and put OE back...

Today I call K&N... they tell me to drill a hole... I drilled a hole. My father removes the Air Temp Sensor from the old unit and it breaks.... now the search to find one... find a dealer 12 miles away. Hop in his car and get it... $36... come back and finish install...


Finally in and running.... it sounds nice when you gun it... no noticeable sound difference during idle or regualr driving... I notice some nice low-end HP, but most of the HP gains appear to be at high end, almsot turbo-like feeling where all of a sudden the thing just takes off...

It's kind of cool! Johnny likes it!

Glad to see I wasn't the only one who broke that flimsy Air Temp Sensor. I did manage to fix it though.

[Billybobs R/T]

ANybody know the part number for the MOPAR CAI? I work at a Dodge dealer and they don't have anything on it yet?

P4510832 is the number from the dealership I ordered it from (not my local shop, but it was a DCX shop).

[Sonic]

I got my CAI (K&N) on order too and the flowmasters should be here Tuesday : )

Excited I am.....Can you all explain what the cam will do for me, Im not that mech inclined?

If your looking for a K&N CAI the guy at

http://www.mikesperformancecenter.com/index.html

Gave me a good price, was 210 shipping and all from the list or adverage 270 prices i was seeing.

[Billybobs R/T]

Hey thanks guys!

[glfelker]

I just installed the Mopar Cold Air Intake. I didn't notice any appreciable extra horses but it looks good and sounds even better. There is no way it is taking in any colder air than stock though. Stock is sealed down to the fender well. The Mopar intake has a heat shield but can get air from engine compartment and the metal tube must add some additional heat. Does anyone know if the filter is any less restrictive?

[Here'sJohnny]

It's not that it's PUTTING more air in your engine, that would require turbo or supercharger (pressurized intake) It is ALLOWING more air into your engine. Think big gulp with narrow straw(OEM) and Wide straw (AEM, K&N, or other) you still do the sucking and therefore limit the amount coming in to what you want... But when you're thirsty... You can empty that big gulp in no time with a bigger straw, you might turn blue with the (OEM) straw! Hope this little analogy helps you....

[TORO]

can anyone please direct me to thread on how to install a k&n cai?

much appreciated
found it !!

[littleJohnnyfromNJ]

don't know of a thread, but K&N gives you detailed instructions.... it is a piece of cake...

I've since sold my Charger but can tell you that the pipes and CAI made a huge difference in performance as well as sound - - - it sounds killer especially when romping on it - - - she opens up an barks loud and takes off!!!

[optimus124]

What's the size of the cone filter for the 5.7?
