I noticed that the engine was a bit less smooth after the trackday at cadwell park last sunday, so decided to take the plugs out and see if they were a bit fouled. Found that the trailing plug from the 2nd rotor was fouled (as were they all) and also that the electrode (i think that\'s what its called - the bit that sticks out over the top) seemed to be about a mm shorter than the others, making me think that it\'s broken at some point. I\'ve attached a pic, although it\'s hard to tell from that.
So what plugs should I get? Currently has HKS / Denso R525 RE, which a quick websearch has told me is between #10 and #11 NGK racing. So should I run 10s and 11s? What\'s the code as well? I\'m guessing BUR11E - something - P ?
Help please - I need to get these plugs quick. :D
I have Racing NGK 10.5s in stock, £15 each.
Only problem is I need em by Tuesday. Jap Performance delayed their photoshoot due to a problem at their end and it\'s now on tuesday. How much do you reckon it would cost to get them to me for a post Monday, guaranteed tuesday before 9am type delivery?
I can that, but my courier charges me an extra £12 for before 9am orders.
Give me call at work on monday morning, and we can sort something out.

I was lucky enough to find a local parts shop that was open today (Sunday that is) and had some 9s in stock. I\'ll run them for now and order some 10.5s in a couple of weeks.
Thanks for the reply.
