Anyone running Iridiums? Have seen alot of banter about not using them or platinums in the hemi's. Just wondering if anybody is using them and what kind of results.
X10 loli'm a dcx certified tech and i highly recommend the iridiums. Yes it is true platinums need to be left alone when talking about most dodge engines with obd2 or newer. I run nothing but ngk iridiums in all my cars and my customers cars.
about the burning up the combustion chamber? um i personally didnt sell that guy the crack but i wish i could have
x2 except I'll only have the predator 91 octane and CAI. I'm due for my spark plugs in 2k miles and wondering if it's worth spending the extra $4 per plug. Lat time I saw NGK iridiums were about $7 a plug. So yeah $3x16 does sound alot better price wise. Unless I'll actually get more mileage out of the Iridiums and my dealer won't give me crap for not changing them as often.so lets say i run 93 oct(with predator - btw i only get 93 in houston, no 91) and have a new CAI and full exhaust.
worth it to run Iridiums would you say? i mean, i spend tons in gas(between stomping the pedal and commuting) and a 100$ investment could be worth it if there is a noticably better increase in gas mileage and even the slightest performance gain
Well I'd be doing the labor too. I'm not paying 1.5 hours of work to change spark plugs. It seems like a pretty straightforward job except for the two in the back of the engine. Where's the best place to buy them for that price? I might order them online ahead of time if I can save a decent amount of money.Plagerism from ngk = Iridium is a precious metal that is 6 times harder and 8 times stronger than platinum, it has a 1,200(=F) higher melting point than platinum and conducts electricity better. This makes it possible to create the finest wire center electrode ever. Prior till now, platinum had been favored for long life or performance spark plugs due to its high melting point, also the technology did not exist to machine and bond iridium on a spark plug electrode(at least in a cost effective manner). Iridium industrial spark plugs have been around for years, but still sells for over a hundred dollars per plug. Just now is the technology available to effectively use iridium in a spark plug for automotive applications. The strength, hardness and high melting point of iridium allows NGK to manufacture their iridium ultra-fine wire center electrode to 0.7mm. One of the finest firing points in the industry! (Thus far there has been no problems reported regarding use of iridium plugs with nitrous oxide.)
I recommend iridiums as i have never,performance or daily, since a plug failure in a dodge with iridiums. They have been ultimately reliable in my supercharged focus/ neon r/t with 20 psi boost and nitrous, and 96 neon with 100 shot. With coppers, which are great , the failures get amplified with mods in my experience. I'd say they are worth every penny of $6 each and would do them strictly for piece of mind myself. However your pocket book is you number one factor. I do all my own labor so 116 for plugs aint bad.
See that's just it, there are no real MPG gains to be stated from using these plugs. Unless someone can find them somewhere. Just going from 89 to 91 octane fuel, you will see a boost in your MPG. As for power, I think the Iridium's perform better with a leaner A/F mixture. This could be a good thing since the Predator will allow changing the fuel tables.Thanks for the input guys!
I don't have alot of performance mods but I am looking to squeeze a little more mpg out of her and if I can run longer on the plugs and get a little more power out of her, all the better.
Think I will go with them.
100 bucks for 60k miles and iridiumsWith the Iridiums I should be able to go atleast 60k on a lightly modified car though right?
yeah but if you're getting a cleaner more consistent spark those 60k miles ins't losing the interest on $50 not to mention the hassle of doing the job twice worth it?100 bucks for 60k miles and iridiums
50 bucks for 30k and copper?
