I have the AWE 620 kit and it was recommended that I have the plugs changed at my 20K mile service. It was a big job and cost about $900 done by an experienced mechanic at a San Diego Porsche dealer. I've heard from many that it's best to take it to pros to have this done - no short cuts are advised. I was also advised to use stock plugs as that is what the software is tuned to.
Good luck!

You can do it, there is a DIY on renntech for the 996tt, but as Bobby pointed out the 997tt is a bit different. Most of the dealers simply drop the motor to do it, ~1100 dollars labor when I did it recently. Yes, a tuned TT will have to have the plugs changed more frequently.

 

I'm sorry, $1100.00 for a spark plug change! I would gladly spend all friggin afternoon on my back in the garage before I paid that!

 

I make a lot more than 1100 dollars in 6 hrs.......

 

I understand the 997TT is quite a different beast than the 996TT for plug changes. I originally took my car to an experienced tuner who had changed many 996TT plugs and he recommended I go to the dealer. I don't think the $1000 to have it done by professionals is worth the investment (of cours I couldn't do it I wanted - no skill, no necessary tools . For those retuning their cars plan for more frequent plug changes. Still, maintanance is reasonable given the kind of car we're driving.
If you try it yourself, good luck and keep us posted how it goes (maybe some photos too?).

My local dealer will charge me 6.6 hours @ 120.00/hour with my little 10% off it should not be too bad. Already bought the plugs, 71.00 or so... not too bad. I will suck it up and have them done, i was looking into a better way as i will be changing them often I thought it would be nice to save a few...
At this point, I am very inclined to open my own shop just to get my cars worked on, i will save a ton every year.

 

If your software recommends stock plugs then i would run with them but if it does not then I would go with the proper set up... it is not really about preference...
I know this is a bit off topic but I had to retune my H2 last month at LGM in Dallas, TX and the first thing they did before even talking me was replacing the plugs with cooper cores and removed the Iridium ones. So plugs do play a very big role in the overall tune of your vehicle.

 

Except a tech doesn't have to pay $60K-150K in malpractice...And his reimbursement rate don't go down 10-20% each year.

 

I have tried to DIY but failed.Only be able to change 1 on each side.TURBOs stay on but all hoses around it must removed.I paid approx $300 USD for a local porsche tuner to change them.They took about 4 hours to do it.

What service manual are you talking about. There is a computer model available that is assessible only to porsche folks and at a $2K price. Post details of any less costly paperback manual you are aware of.

 

2 things.... I was wrong about the plug change being similar. The turbo location and additional plumbing on the 997 makes it more complicated. Some slide the turbo forward, others unbolt the headers and let it hang down a bit.

Secondly, the manuals that I know of are genuine porsche from "porschelibrarian" on renntech.org. I think all print went away 4-5 years ago and only thing available now are pdf files.

Good luck to you.

 

For access to spark plugs, some say bumper comes off and another says engine dropped. Which is correct? This may be best time to upgrade the exhaust costwise...at least some of the labor is paid for.

 

I would say that all of the above, from what i am reading in here It Sucks, It is Hard and It is Costly!!

 

Service manual was available online at https://techinfo2.porsche.com, but that site has been taken down...I only purchased a few chapters...nothing on the plugs.

 

FYI guys... it IS a bigger job than on the 996TT. A PIA
