Looks like Champion have discontinued the N8 spark plug and the replacement is the N5?

The champion plugs to use are L86C in SV's and L82C in OHV or much better still Bosch W8AC and W7AC. respectively.  Ron

I've never had a problem with champion plugs(so far)

When L10S were obsolete I used the L82C and still do in my C11's
Now the N8 is obsolete I will see how a N5C works on my alloy head C10.
I have not had use for a L10 which is now the L86C until I got the 45 C10 with an iron head (still on old champion plug)
