Best LT4 performance spark plug?
I have the stock LT4 engine with Corsa exhaust and Vortex ram in my 96 coupe which I drag race as a hobbie and I'm always looking for simple performance improvements without doing any major engine modifications. Therefore here's the poll: What do you recommend as the best performance spark plug for the LT4 Vette? (Currently I am using the Bosh Platium 4)
