On this note, dealer tells me it's $500 to change the spark plugs on my '08 HEMI. Says the brake booster has to come off and all that. Is this true. I'm a mechanic, and I instinctively second guess what the dealer tells me as far as labor time and cost. I have heard that some people have done it themselves, and was just wondering if it really was this much trouble, or if it could be done yourself in the backyard. I realize there are 2 spark plugs per cylinder, but the dealer also told me the plugs were $16 each. This seems a bit ridiculous to me when most places I have read say that the OEM plugs are just basic Champions. Any help is much appreciated. Thanks.

With a few hours and some patience they're not too bad to do, the ones at the back by the brake booster are a pain but no need to pull the booster off.

I can't find anything in the service manual (installation or removal) that says the brake booster has to come out. Others have reported that a good assortment of extensions, swivels and some patience and you can do it yourself in a couple hours.

I thought the Iradiums were ok but platinum plugs were no good?

Correction: If you are a lazy, over-charging *******, then it is definitely necessary that you remove the brake booster to change the rear spark plugs. Better yet! Just pull the whole freaking motor out! IT'LL ONLY TAKE 10 MINUTES THEN!!! HA!
