Galvanic Corrosion?

I'd rather them potentially coming loose rather than stuck in the head pulling the threads out - 100K change intervals. I replaced mine at 10K and it was very uncomfortable using the force required to get them out - never had a problem using the antiseize on the VX or my aluminum race skiis in the gulf.

Tone, did you miss this part when reading?

Torque is one of the most critical aspects of spark plug installation. Torque directly affects the spark plugs' ability to transfer heat out of the combustion chamber. A spark plug that is under-torqued will not be fully seated on the cylinder head, hence heat transfer will be slowed. This will tend to elevate combustion chamber temperatures to unsafe levels,and pre-ignition and detonation will usually follow. Serious engine damage is not far behind. An over-torqued spark plug can suffer from severe stress to the Metal Shell which in turn can distort the spark plug's inner gas seals or even cause a hairline fracture to the spark plug's insulator...in either case, heat transfer can again be slowed and the above mentioned conditions can occur.


i have seen first hand what happens with pre-ignition and detonation. it is not a pretty sight.i am not saying to use or not to use anti seize but you do not want the plugs too loose or too tight. shawn
