Hey guys,
I've decided its time to get some new plugs for my 33 as i can tell the old ones have had it as the car is backfiring alot, now ive read through the forums and stuff but i want to know what everyone recommends. Ive read that RB20DET plugs might run cooler? and what gapping should i get, i will be purchasing iridiums. Thanks guys any advice would be helpful!
