I switched to the E3 46 plugs. From ngk. Now I’m back with ngk. I won’t say they have never failed me, but I’m not demanding much out of these. They saw 5800rpm, and 13psi. I started noticing a miss at idle, then a miss under boost. It was a lot more prominent once I switched over to wasted spark.
Look ma! No distributor!
I added the second bip373 coil driver, and rewired the coil power and stuff. Pretty decent for fighting a spark plug all day.
