Hey Rick,

I know you have covered this, but for the learning disabled, one more time....

If your '03 is the second run and has the AGSF22FM1 plugs, which are the same heat range as a NGK TR6... why change?

What do you recomend with 13 to 15 lbs of boost? and at what gap to prevent blowout?


:confused: :confused: :confused:

I prefer running a copper plug and the NGK's have never failed me under extreme conditions. At 15 lbs of boost I would go to .035 to be safe. I have not tested the FM1's enough to say that they will be fine under increased boost. They are in my car I just got so let me do some pulls with it and check them.

The NGK plug you are using is the TR6? Please keep me posted on you progress, as I will keep you posted on mine...
