I did the plugs and coils Yesterday. I got a set of the RS3 coil packs:
I warmed the engine up for like 15 minutes.
Pulled the coil pack heads off, and sprayed silicone down the small hole.
Waited.
They pulled off.
They were not heated to the plugs at all, they are just on tight down there, and it's
just a bad friction area. I even put a boot on a plug without the core in it, and I still
had to pull hard to get it off the plug.
When I was pulling the boots off, two of them flung, and the cores flew out, and
I had to go looking for them... I kept them, they all still work.
Thing is, the OEM plugs were were gaped at .036, and one was .038. I gaped mine
at .032, and the car runs fine. Not sure if I should take them out and regap them or
not... Real smooth idle too.. Will test under the +4 boost on the road today. Then
try the +6 setting.
