[s-cars] Spark Plug Torque

[John Tilden]

I have always used the following procedure for torquing spark plugs, in all
my Audis and Porsches and other aluminum cylinder head engines.

1. Insure that the internal threads are clean, chase them if needed.
2. (here we go) Always use an antiseize on the plugs, there are Catalytic
Converter compatible antisieze materials out there!
3. Screw the sparkplug in finger tight with the end of the extension as the
tool with which you apply the torque.
4. Tighten the Spark plug an additional 90 degrees of rotation with your
Wrench Handle.

You are done! Never had a plug back out, always come out easily next time!
Been doing it like this for 40 years no problems ever.

Remember what you are doing is crushing the Washer to a specified thickness.
