spark plugs

Post by Red Baron » Thu Jul 22, 2010 8:11 pm

Hi, just wondered what plugs people are using. I need to replace my current set which are NGK B8EV and my local speed shop dont stock them any more. I run a 930 with an R20 on Hillclimbs.

Thanks

I as surprised that you are using B8 plugs, I use B8 in the race engine, B7 in the fast road and B6 in standard engines.

Yes thats what the engine came with and I've just stuck them, perhaps some 7's would be better?

Always used N9YC(C) as found them far less fussy and not prone to fouling ,this was for rallying where you are often running at idle for long periods at stage starts. May be a different scenario for cicuit racing.

I run a 930 with R20 in my Ginetta G15 for road (going to work etc) and hillclimbing/track work and have always used NGK BP6ES with no problems other than slight fouling after long periods at idle (town traffic)
Cheers, Simon.

NGK is "forgiving" spark plug. Use them in all my cars (If's possibly)
I have just bought new batch for the spare parts shelf, NGK V-line series, BP6E . Haven't used them yet. Supposed to be even better. Time will tell.

Decades ago in my karting days the the two-stroke world demanded Autocraft racing plug. Easy to foul, and if they had, no spark any more. So I got NGK racing plugs and no more problems.
