PLUG recommendations for 95 ZR1 - ZR-1 Net Registry Forums

doc8877a · 08-23-2009

I just picked up a 95 ZR1..with 28K on it. It has been garaged for over 2 years. I am in the process of changing ALL the fluids [including gasoline]. This car has a K&N filter and a POWER EFFECTS exhaust system. I have trying to decide what spark plugs to use. MY head "hurts" from reading all the available information over the last 8 hrs today. I will be driving the car during APRIL to OCT..nothing super hard ..just enjoying it. I was considering IRIDIUM plugs from NGK or DENSO.. but there seems to be a conflict on which part # to use ..depending on the web site. I have also considered the DUAL Platinum plug from NGK or DENSO. Again, however, there seems to be an inconsistent agreement on the correct part #.

I really have not considered AC DELCO, but would take a look at them.

Can someone give me the correct part #'s for all the DENSO and NGK plugs that will work properly in a 95 ZR1 with DUNN heads both sides. I would also like some suggestions on "gap" as this seems to also change from website to website.

All I want is the longivity of the IRIDIUM or DUAL PLATINUM plugs..as this ZR1 will be lucky to have 40K on it by 2014. Any and all suggestions will be greatly appreciated.

Thanks Doc in MI
