I remember reading some where that for approx every 75hp increase you should go one rating cooler for the plugs.

The std RB20DET plugs have a heat code of 5.

I am running 1 bar of boost fmic exhaust ebc etc.. and are using heat code of 6.

Whatsisname is making almost 240rwkw and has just changed to heat code of 7.

I'm actually running '8' at the moment (I changed them for a track day, and found one of my '6' seemed to be damaged around the base of the ceramic).

Now for the question - will running too cold in the plug cause the engine to run too hot?

NGK Idirdums for the RB20DET part code is bcpr6eix or -11

without the -11 its pregapped to 0.8m

I just put some of them on & man did the car feel like a new car.

When you purchase them make sure u dont buy it no more then $18.50 since rrp are $18.50 as advertised on zoom & other car mags.

Spoke to Ben @ NGK, he advised that the plug should not affect the engine temp. So it seems I need to talk to the radiator man.

BTW, I'm normally running PFR6B-11. NGK make a PFR6B, gapped to 0.7 - 0.8, and a PFR7B, gapped to 0.8(?).

I use NGK Coppers 6 heat..

Hrmm Not the best ok if you don't want to stuff the good plats due to running rich.

I get a slight rough idle from them.. Slap in the Plats and a perfect idle.

They are also starting to get hard to start first thing in the morning. New plugs.. I guess. they have been in there for a while now.
