Who needs Viagra??!!!:smoke:

No, really..... just put a set of 16 new spark plugs in (32k miles), it was time. I used Champion Double Platinum Power Premium Plugs. Cost was just under $70.00, and now I'm going out to set them afire!! Busted up only 1 knuckle too doing the job! Job was easy as pie though. Also put them on with Lithium anti-seaze grease on the threads, and dielectric grease on the tops before plugging the boots back in. The old plugs looked like they burned pretty consistent, with just a bit of black carbon on each, but the gap did open up a little over the .45 to around .48ish+.



OK... time to fire them up. Be back later to give a report if I feel the difference.

Well just got back from a short run around the neighborhood. She's runs nice and smooth at a light, and there really is no difference (maybe a little) in performance. Guess the old plugs weren't that bad to "feel" a difference. I'll take it as good thing... meaning my engine is running up to par after 32k on it. Like I said, the old plugs weren't that fowled anyways.

My brakes SUCK.... they replace the rotors once for free.... I was going to do pads today too. But after I pulled the wheel off AND then the caliper (another 1/2 hour) the pads were fine. Seems like the cars rotors (once they heat up) are just garbage. After constant heavy braking I get the "shimmies". Might be time for me to upgrade to a set of slotted or slotted and drilled ones. Thats if the wife will let me!

I have about the same mileage. Guess I'll wait another 10k or so before I plug my honey, thanks for the report.

I'm gonna do this next week. I think she can last another 600 miles. The amazing thing is the dealer just serviced my car and didn't even try to upsell me a plug job. I would have said no anyway.

Same story here, Rich. I was hunting a noticeable dip in mileage when I did my 30K plug change but it turned out to be a cracked vacuum hose (PCV, I think). No big difference in operation after the change (and after the hose was changed it went right back to the awesome mileage and performance I was getting all along). Like yours, I noticed very nice wear on my plugs at 30K with only a small increase in plug gap.

I was making the effort to number each plug in case I need to reference them sometime down the line, but it was time wasted: they all looked the exact same. For those who are concerned with MDS causing irregular wear, at least the plugs aren't showing signs of it!

I always found 30K to be a bit early for plug changing on a modern high tech motor... maybe it was DCX being initially over cautious with MDS and never bothered to readjust their change intervals after it became clear there'd be no staggered wear? (might also have triggered many complaints from older Hemi owners who followed the 30k interval for no reason, and wanted compensation for the unnecessary expense).

Well after todays run to work and then back home, the car does run a bit peppier, but nothing to brag about. What I notice the most is that my trans is slamming through the gears better. She has that neck-snap shifting back (I run on autostick 100% of the time, with ESP off), which I've lost before the plug change-out. I know one doesn't have to to with the other... but its about the only thing I really noticed at this point. Could be just my imagination though. Other than that really no change to get excited about.

Just plugged my beauty with Iridium IX Spark Plugs and she is loving me for it.
Some knuckle blood, but worth it. She has never run this good!

After plugging and cleanup, the only problem is the check engine light is staying on.

Any ideas?
