You might add:

Put a little anti-seize on the new plug's threads to keep them from getting stuck.

Doesn't sound very complicated, maybe a couple hours worth of work? Might pull mine just to see what they look like - make sure it's not running poorly since I got that P1129 code a couple weeks ago. I also need to remove and clean the MAF soon, too.

Bill....I know I only have 4900mi on the car, but I couldnt stand the idea of having the same plugs in my car for more than 3 years. I get neurotic about stuff like that

How many times did you wash your hands when completed?

Did you use torque wrench? If so, did you adjust torque with the anti-seize compound? Thanks!

If you jack up one side of the car at a time you don't need to remove the wheel well cover.

Hi,

You can change the plugs in as little as 20 min. You should use a torque wrench to insure that the plugs are properly sealed and indexed. Also, Anti-Sieze is unecessary and you run the risk of overtorqueing the plugs and stripping the Head (aluminum).

As mentioned, lift one side, slide underneath (I use a creeper). Loosen and the Coilpak screws at one time, pull the Coilpaks after marking them w/ paint pen or tape to avoid mixing them up. Pull all 3 Coilpaks (pull and slight twist). Untorque all 3 plugs with ratchet handle - not torque wrench. Hand loosen all 3 plugs and remove marking them (Cylinder #) for later inspection.

Check Gap on all new PLugs and adjust as necessary - they come pre-gapped but are notorious for being off which will affect a smooth idle. Check Spark Plug Tubes w/ finger to insure no Oil leaks. Insert and hand tighten all 3 plugs. Torque plugs to spec in 2 stages.

Insert Coilpaks on plugs, following the labels. Insert Coilpak screws on all Coilpaks - hand tighten. Torque Coilpak screws in 2 stages. Go to other side - repeat. Hope this helps...

Happy Motoring!... Jim'99
