Plugs

I used HKS iridiums, S35-????, set the gap to 0.8mm if your running higher than standard boost. I had a misfire problem when I turned the boost up. These plugs sorted it right out.
I've heard the Greddy ones are more durable (after I bought the HKS ones).

I was £17each. I bought six, got home the noticed they gave me eight and only charged for the six! I'm not sure about the NK ones. I think you can search for the part number on NGK's site.

Yes you can get ngk iridiums to suit yours, speak to rising sun performance or send him a pm. I paid £48 delivered for a set of six
