im running a 98 ex with a greddy turbo kit.with stock plugs i feel the car breaking up when in boost. i think i need new plugs b/c the 1s i have are shot. im thinking bout getting ngk iridium plugs.wat do you guys think? thanks
if you are running boost you should NEVER run anything besides coppers. Just get the NGK 2 step colder, i think you want the heat range 7 or 6 and gap them to i think it was .30 but don't quote me on it.
