Just a side-note. The bolts on all of the coils were just barely snugged up...little more than finger tight. The car was relatively new to me at the time with around 130,000kms on it and the coils I took out looked like new. After I completed the entire job, the thought occurred to me that maybe an experienced Porsche mechanic intentionally left them loose to allow room for them to expand and contract without cracking. I have seen some pictures of badly cracked coils. Anyway I tightened up the new ones so I'll see what happens.

If you do not want to loosen the headers, just make sure you have good wobble extensions and you should be OK. You just want to be careful not to get them in a bind and begin cross-threading the plugs...So just take your time and be careful...once they are started, you should have no issues.
Good luck.

Have the ball end torx coming from the UK and I have a full wobble set.

You shouldn't be.. as Rock says, take your time and it's not bad.. as I said in a previous thread, I'd rather do my plugs again than do the GT2RS intercooler custom install over again

I'm a relatively new member & just purchased my first Porsche - 2010 PDK Turbo Cab.
I enjoy working on my car as much as most of the members and recently embraced the infamous spark plug change.
I have to admit I was a bit apprehensive and relied on several forums to educate me prior to moving forward, the Rock's post was invaluable.
I was surprised to see that it wasn't necessarily easy but was not terribly difficult. Take your time and refer to the information shared by those who have been down the same road. In my experience the drivers side was relatively easy - I had access to the plugs.
The passenger side was a bit more difficult especially the center plug. Definitely remove the VTG which will allow you to gain access to the coil and corresponding plug.
Good luck and reach out if you need any insight.

At my engine-out service next week I "may" end up with a full set of plugs,.. but only 4 new coils,... with the other two arriving later.
If those two don't get there before the engine goes back in,... I'll want to be sure to leave the 2 easiest left to be done.

On a 997.1 Turbo,... which two are the easiest coils to change?

If those two don't get there before the engine goes back in,... I'm hoping they can be on two cylinders that aren't hard to get to.

Be sure to replace the two coils towards the front. I would leave the most rear two on the passenger side (US) for changing at a later time if this is your case.

Thank you very much. Will do.

Did not see your note...As stated, the two closest to the front of the car are most difficult. You can easily get to the rest..

Another successful use of these instructions. Couple notes, I didn't lower the engine for the passenger side, although looking back it would have been easier. For the drivers side, after lowering the engine I was able to get to everything and I didn't need to remove the VTG actuator.
Here's the drivers side with all the coil packs out, actuator in place.

Great write up Rock88, love that you have the tools required included, thoughts on the lifespan of the coil-packs? at 77,000 now. Does the Bosch 0986221016 ignition coils fit better than the Beru?
sorry if this has been covered before just got the 08TT a few days ago.

Coils may be about the same....should just check them for cracking as indicator or time to change.
