Had mine done at Sonnon Porsche for $695 and used a $200 off coupon to bring it down $500. Thats why i did it with only 28k miles on the car. Didn't notice that much of a difference afterwards but my car is bone stock. I guess it seemed a bit more responsive but nothing drastic.

 

My shop changed mine for free when they were changing the clutch (engine was dropped as well as the transmission), that's the only reason I changed them with only 13k miles on the car.

 

gmoney: To change your plugs, did you do it at 40000 like recommended? And if so did the plugs look like they really needed changing? Seems like a lot of cash to change 6 plugs, if not really necessary at 40000 miles. My 07 turbo runs good, seems a shame to tear up everything if plugs not really required.

 

Any different afterward? Which plugs did you end up using?
PS. hows the clutch?

 

sorry, read most of the comments, i own my own repair shops and i decided to do the plugs on my car a few thousand miles ago, it took us 6 hrs and thats the first time any of my techs worked on any porsche.

The bumper, exhaust, rear wheels and intercooler tubes from the turbos to the intercoolers have to come off... TURBOS CAN STAY ON! REPEAT TURBOS CAN STAY ON... we loosened the screws that hold the turbo in place and slightly shifted it a hair to get to the last 2 plugs.

Only reason it took us 6 hours was because 3 of the screws holding my oem exhaust at the time were stripped. Now if you have an aftermarket exhaust (which i do now) which is less bulky, it should be easier. In the pics you will see that i didnt even take the exhaust fully off, just because of those screws.

In the pics you can see the 3 square holes where the coils go, those are a bit tricky to get out so take your time to make sure you dont rip the rubber.

The next time I do the plugs, it should take us around 3-4 hours, its not as bad as it looks.

 

stock plugs gapped down as per Todd. Clutch is great. Here's my impressions:

Not clear here dinorocz. I assume you are referring to the screws that hold the turbos onto the exhaust manifolds ? If these screws need to be loosened then why not just loosen them a bit more, remove them and take the turbos off? Or is there more to it....getting the turbos off? It looks like all the plumbing is disconnected from the turbos anyway so the only thing left really is the oil feed lines...correct? That way you have unrestricted access?

 

When I did my plugs, I found out really quick its WAY easier to remove your turbos...You can change the plugs by leaving them in but to me it's not worth the headache...Only downfall from dropping the turbos is you will loose some oil/coolant....

 

Hey Speed21, to answer your question, all the oil lines that go to the turbo seemed to be a big pain in the a$$ to get off, so we figured, lets try and see if we can fit our hands to get to the ones furthest towards the front of the car on each side. We were successful, however, the one on the drivers side also has an added obstacle, there is a sensor or solenoid of some sort (cant remember) but it does pose a bit of a pain to get around. Hope this helps... If you have any mechanical abilities and have changed the plugs on any other car (and are not scared to work on your beloved Pcar) then I suggest trying to do it, but make sure you have a lift otherwise not worth the headache.

 

Mine were changed around 20k, they did not need changed. Im going to go to 30k intervals now.

 

Thanks dinorocz. Equipment and expertise is not a problem my end, but always like to know any shortcuts where possible. Its a job i may entertain in the not so distant future when i do the ICs. Just didn't want to go to the trouble only to find the turbos are better comming off in favor of skinning the knuckles on inevitable obstacles.

 

no problem, I've read many of your other posts and I know you have some expertise, I think this is something you can handle yourself and it should be a good "2 birds 1 stone" deal when you decide to do the IC's, btw which brand coolers are you going with?

At this stage it'll be the .2tt coolers unless anyone can give me a good enough reason to use something else.

 

I ve changed 996TT and 997TT plugs my own...If 996TT has stock exhaust,its difficult without removing it...If it has AM exhaust(thinner cats),there is no need to remove even the rear bumper... Now about 997TT things are worse...Bumper and ICs need to be removed and step motor of the right side VTG unit needs removal too...Whole process takes about 3 hours for one person.No need to remove turbos or engine...
