Opinions on these spark plugs please
Plugs on driver side bank look pretty damn rough. Lots of **** caked up on them. I started to clean one of them before I took the pics. After I cleaned it I decided that was a waste...just replace them. Would like some opinions on why they look this bad. There are not many miles on them, I only drive it once a week. The setup is....
LQ4 6 liter with diamond dished pistons 9.1CR
228/234 114LSA FMS cam
D1SC Procharger 14PSI
And all normal bolt ons
