I have using the number 8 plugs which are hotter since 2003 . Never had any issues with them. If your oil check valve leaks into the crankcase form sitting overnight draining and refilling to 1.5 quarts is a proven cure for that problem.

Hi,
Just curious did you ever try the Brisk plug?
Thanks
God bless...

Nope. Stuck with the Denso. Seems to have stopped fouling as much as it used to as well.
