Spark Plugs

[scotty_1989]

Hey,

im wanting to replace my old sparks on my r33 gtst series 1. Atm the car only has a pod filter and a cat back exhaust. However next week shes booked in getting a full turbo back, i should have a front mount next week too. Im also trying to find an EBC around the place so i can run 10-11psi.

I wonna buy iridiums, so any advice would be good. Im pretty much just not sure what gap size i need for those kind of mods.

cheers

Go with NGK Iridiums / Platinums.

From memory the plugs come pre-gaped, if you ask for specific model of car.

But I would check the gapping no matter what.

From memory, 1.1 gapping is in my head... I could be wrong...

Best check with your mechanic with the gapping size.

personally i wouldn't bother with iridiums. in my experience they aren't worth the extra money.

as far as getting the plug gap, they generally come pregapped at 0.8mm unless they have a number after them. so for example BCPR6ES (which is the copper plug most people use) is 0.8mm gap, but the BCPR6ES-11 has a 1.1mm gap.
