Can you be more specific? What tools did you need? On my boat, I had to take the exhaust manifolds off on both sides! Major PITA!!

Re: Getting to spark plugs in hemi

Do you have any extensions? Extensions will be needed in this! I forget what length's. That's on you! You don't need to remove anything! Just be Patient and go slowly doing the Rear Spark Plugs because you don't want to bend the Metal Tab and making it touch the Anoid causing Misfire (NOT GOOD)!!!!!!

Re: Getting to spark plugs in hemi

Just how much would it cost to have the plugs changed for the hemi? This has to be hugely expensive. The changing interval should be a modern 100k.

Re: Getting to spark plugs in hemi

It only cost me like $33. I got the Stock 570 Champion Plugs from Advanced Auto Parts.

Re: Getting to spark plugs in hemi

The double platinum # is 7570. They'll last 100,000 miles, but cost more than the copper plugs.

Re: Getting to spark plugs in hemi

They're an even bigger nuisance on the SRT8. The stupid strut bar is in the way. Plugs aren't as cheaper either. $6 per (wholesale), times 16 plugs.

I've had the plugs and coils sitting here for weeks. Just too lazy to swap them. Figured that I'd let the shop do them when they do the cam and pushrods again since they gotta come off anyway.

Re: Getting to spark plugs in hemi

I just did my spark plugs today. Man what a pain in the ass! It took me 3 hours for all 16 plugs. I took my time, and checked the gaps, used dielectric grease, and made sure everything lined up. Talk about a tight fit on the 2 rear cylinder coils! I busted the hell out of my knuckles trying to reach those tiny bolts... LOL! But my baby runs like a champ again! The old plugs looked like doo doo....

How have you gotten 2 years of life on those plugs already?

Re: Getting to spark plugs in hemi

I did my plugs at 50k. When I pulled them they looked good. I thought it was a very simple job to replace them. Just have the right extension. I think the maintainence schedule for my GC is ridiculous. I have never had a car with such short maintainence timeframes. Really my only complaint on my GC.

Re: Getting to spark plugs in hemi

For those with Hemi motors, do NOT use Platinum plugs. Check out the Jeeps Unlimited forum for reports from people who thought they'd upgrade and how it adversely affected performance/driveability.

Re: Getting to spark plugs in hemi

Champion recommends their 7570 double platinum's for replacement through 2008. Cylinder head plug seat type changed in 2009. Heard Champion's working on a replacement. Champion's have a 5 year unlimited mileage warranty on the 7570.
