Would like to here from some of you Hi-Po ZeTec turners out there what brand of plugs you're running and if you notice differant performance results from switching between brands.
I know the factory spec calls for .050 gap and up to .065 with some heavy duty coils but, widening seems to cause misfires at higher end RPMS. Is this bad plugs or too much arc/gap?
some ideas or experience on this would be appreciated////////
