Hiya all,


What are the differences between CR8EH-9 an CR9EH-8 spark plugs?

What are the differences between standard and iridiums?


I'm going to be scratching the NC29 along welsh twisties next year, rather than track days. I'm guessing I will be revving her, but not redlining all the time.

I'm guessing Iridum straight off

But what about the type of plug? CR8 or CR9???


Hope you can advise
Cheers
Martin

I only use CR9EKs... and have never had a problem... never tried anything else.

CR8 for mixed riding, CR9 for mostly flat out hooning. Iridiums are highly recommended, and use CR9HIX because even though it's a hotter plug, it won't foul during slow riding like a regular CR9 would.

I can only find CR9EIX.

That's the bunny, I got the code wrong.
