Hi peeps. Iv got a r33 Gtr. I want to replace the spark plugs. It's running 1bar and 437bhp. I'm just trying to find the best price and plugs! I think heat range 8 will be good. Iv got a misfire on cold start and once the boost starts to build. I feels like the spark is being blown out. The plugs are old though.
Thanks

Jeff

I was running greddy 8's at 1.2bar they are good

We're can I get them from? Any idea how much?

Clark Motorsport stocks them

I am going to switch to copper plugs are they are cheaper and better imo

These are the ones: BCPR7ES

Just so this thread is a little clearer...
Copper is better?
It depends how you look at it - copper plugs need changing a lot more often, though perform better (cleaner/stronger spark) than the likes of an Iridum plug. Though as I understand Platinum plugs are the best of both worlds - though yes, then of course you bring costs into it

We service our cars so often it's a waste of money buying iridiums imo.

I wasn't arguing - just confirming detail.
