E3.74 spark plugs
 

I want to try them in my 2018 Camaro SS has anyone use then in their car

Stick with the factory AC Delco plugs or the equivalent in NGK.

^^^^ THIS... I have read in the forum some where someone was having issues with the E3's they were running, went back to stock plugs and good to go. Or as stated above and a lot of us, equivalent NGK's..

Ran them on a Corvette I had. They sucked went back to AC Delco and engine smoothed back out...

On my Camaro I run NGK's with no issues

JUNK>>>>>>
