AC Delco Rapid Fire

 

I don't have an LT1 but I run AC Delco Iridium plugs in all of my GM vehicles. Took em out of my Camaro at 150k with 45k miles on them and they still looked almost new haha. No change in the gap or electrodes at all.

 

right on, ive heard alota good stuff about all iradium plugs. i love ngk for most cars. bosch, im not sure, but they just seem faulty even in my girls jetta, although that thing is a pos. talk about crappy, damn *****

 

I installed the Delco iradium plugs and I am very pleased with them.

 

NGK TR55 in mine.

 

Ran the same Bosch + 4's for 7 years, switched to the TR 55's and got 1 year, went back to the Bosch + 4's.

 

really, were you having problems with your car running or anything. i think running lean burns up plugs
