NGK7. I use HKS SuperFire Racing, but ordinary NGK are fine.Need some new spark plugs for my r32 gtr with an r34 n1 engine running 500bhp and not sure which plugs or heat range to get?
I find the iridium NGK ones to work nicely.NGK7. I use HKS SuperFire Racing, but ordinary NGK are fine.
I reckon you know that the plug is shorter.Get 8 heat range. I run BKR8EIX. They're the iridium version of what dan runs.

Have you had any problems running with the 8s?
Noted Dan.There's a spring in coil pack so it makes no diffrence
and so I pulled the plugs out today and this is how the plugs were ..
Looking at the condition of the plugs, I can't help but feel that something is not right ..
the plugs were fitted less than 3 months ago ... I have only brought the car to track once, and other times were using it as normal...
any idea why they have become like that?
Using a HKS F con v3.4Hi
What ECU are you using? do you have a wide band on the car? give us a call ask for Garth he will give you some good advice.
