Re: Is a cooler spark plug required after WI fitted
usually with forced induction motors with increased manifold pressure
could cause detonation from the hotter heat range...
this is usually why we drop down to a cooler heat range plug.
but without an egt gauge to monitor the temperature it will be
conjecture / educated guess.
besides it would be nice to be able to monitor the egt's
and watch them drop when the water/meth starts spraying.
was stock heat range 7?
