Wow what a difference! I was getting a cylinder number 4 missfire for the past couple of weeks, and a slight bit of a break up on full load in 3rd.

I installed a set of ngk bkr7e's gapped to .026. This was the first time i had instaled plugs on a 996tt or a porsche 6 cylinder for that matter. Although you have to remove a lot of stuff ( wheels bumper intercoolers coil pack covers etc) i found it to be a very straight forward job, As if they engineered it to be done easily.

Once i was ready to button everything up i paid special atention to my upper intercoolers hoses that i had made to go to the speedtech intercoolers. I am certain that i had a boost leak from them earler. I fitted them well and secured the t-bolt clamps down securly.

While i was there i also drain the oil and turbo chargers and gave it a new oil and filter. I also gave it a bath afterwards

All in all the car now preforms as it should its now back to being a BEAST!!

 

ngk bkr7e - you sure? It is sold as a motorbike plug...

 

Yes Bkr7E's

One of my biggest hates is poor design and engineering

I did my plugs last week, and other than one of the O2 sensors getting in the way when screwing one of the coils back in place I found it to be a "nice" job to do - very well laid out given the space constraints

 

I don't take off the bumper or the intercoolers. I use a very short 5mm on a 1/4'' flex head ratchet. It just a bit tough to get at the coil harness plugs.

 

Is there a DIY for the spark plugs? I plan on changing my intercoolers to 997.2 and while I'm at it I might as well change the plugs since the IC's will be off anyways.

Thank god for the DIY section. I was curious to see how much the dealer would charge me being as I was feeling a bit lazy. They said it would cost $1065 in parts and labor!!! Yea no thanks. Ordered the new Bosch spark plugs off amazon for like 45 shipped.

 

How did you know this? Were you getting codes?

 

Same here - with a lift it's pretty easy to acess the coils & plugs from directly underneath. I removed everything the first time (Bumper, IC's, etc.), then was told/shown there is no need to...I did a complete coil & plug change in under one hour, all from underneath the car. It's a lot easier this way.

 

yes i was getting a code for cyl 4 missfire.

 

Wow the 996 must be way easier than the 997tt...I changed my plugs on my car and it was a B*tch!! Took me several hours and said about every bad word in the book!

 

The only way you can be assured is to do a boost leak test from the turbos... everything else is wishful thinking... OEM cars even have leaks..

 

Would I be able to do This just by putting the read end up on ramps?

 

Yes, I have those rhino type plastic ramps and the rear has enough clearance to back on to them. It gives you plenty of room to remove the bumper, use a creeper, or whatever.
They won't clear a stock heigth car in the front. You'll need to use wood to step up and pull onto them or if your garage has a lip at the door put the ramps on the down side and pull on them.
