NGK Iridium Spark Plugs

The gap is not set for responsiveness. The idea with setting the correct gap is you want it as wide as possible for a better burn without the cylinder pressure blowing the spark out. As cylinder pressure increases, you need to shorten the gap so that it doesn't blow the spark out. The other alternative is a better coil pack, but that is typically only needed with much higher power.

Spot on. Gap is based on pressures which is influenced by boost pressure (hence why you gap down as boost increases). Insulator thickness is based on cylinder operating temps which are a function of boost, compression and fuel.

Great info. Thanks.

I use feeler gauges. I make sure only the .026 fits lol

So I'm the only TRX owner who uses his manhood to check the gap? I thought it was a universal issue and why we buy TRXs.
