need help deciding what sparkplug i need with 4.8L turbo New to the forums here.
Ill give you a little run down of whats going on.
Car is my 91 Toyota Supra
Motor is from 2001 Silverado 1500 4.8L with matching 4L60E trans
GT45 turbo(ebay)
AEM water/meth injection
FMIC
LS6 yellow springs
LS6 cam
Hp tuners
Walbro 400 fuel pump
A1000 adjustable fuel pressure regulator
LS1 intake
42lbs for yellow injectors(bosch)
Top piston ring gapped to .028
3" intercooler piping and intercooler is 31x14x3
On 10-15psi what would be a good spark plug to run?
Thanks for any help
