Spark plugs ? Denso it-22 iridiums? - ZR-1 Net Registry Forums

Looking to swap out my AC Delco plugs in the spring (that's what came with the car).......Car is a 91 with some mods- headers, exhaust , top end porting...

I see some members are running the Densos.....Any recommendations?

Of course I will check before I install,but, do they come pre-gapped?

Thank you...
