Just curious if anyone has done this and if there are any other components needed aside from the spark plugs when changing them? I have about 35k and am past 4 years now. I was planning to order just the plugs but am seeing various gaskets/rings and cant tell if these are related to the coil packs or are for something else.

Also from what i can tell, do i basically just need to remove the wheels and heat shields to access the coil packs/plugs?

Thanks

I was gonna do this but got lazy and let my mechanic do it. My understanding is its mostly pretty easy, but 1 of the plugs is real tough to get to. Some people say it's worth taking the exhaust off to make the job easier.

The spark plugs are in plastic tubes. It's a good idea to pull them when you do the plugs and at least check them and replace the o-rings. You'll need a boat plug or something similar to pull the tubes.

When you do plugs you'll also want to at least check the coils and some may need replacing.

See for example :

Was thinking about doing them myself but also don't want to dig in there and discover I have one or more bad coilpacks which would then have to be ordered during the job. I think I will just let the dealership do it for me. It's a little hard on one side versus the other. For a 997.1 Turbo--it's a nightmare--you have to pull so much off first to get to them.

Check this thread, lots of useful info. There were no 'tubes' in my 997.1, I think only the 996 had them but not sure, maybe PAG did a mod on the M96 engines for 2005.

One thing I did that helped the most was to drop the mufflers, a half hour job that makes the job possible. Remove the fender support first. 3 bolts hold on the muffler, disconnect the muffler clamp.

I watched the P-dealer tech change the plugs without removing the bumper or exhaust. It helped that the car was on the lift and the tech had the right tools. While it looked straightforward I was glad to pay the $300-$400 and be done with it.

Having said that, I am still po'd the dealer (Porsche of Tysons) charged me $30 per plug in parts costs....price should've been $10 each.

Yeah it's nice to have those factory tools and a lift...and working on your back in contorted positions is a real pain in the neck, literally.

Maybe I'll have to undertake this project. I have the tools, and small hands!

I was looking up parts for the spark plug change. The "tubes" mentioned are just for 996?
997 has no tubes? If no tubes, then do not need to order the two sealing o-rings per tube either, right?

sullivas

Right not necessary.
As I remember there is a o-ring that resides inside a groove in the spark plug recess. I didn't replace mine. I think it is just a dust/dirt seal.

One man's saga.

I see no reason to change the plugs at that low a mileage. Wait until at least 60,000.

Expect to pay about $15-20 per plug, don't let the dealer ding you for the full $30 price.

Check the coils and change them, infact, if the car is still under warranty, just have the dealer change the plugs when they change the coils. Everybody seems to have the coil issue at one point or another, sadly you need to wait for the problem to occur before they're do anything about it. My dealer ended up changing all 6 coils under warranty when one failed.

Actually i found the oem bosch plugs at rock auto for 8 bucks a piece shipped. Yeah my big concern was that removing the oem coil pack would induce some type of stress upon the housing as it seems to be very fragile and cracks easily.
