I use AC R43XLS. Extended tip is the difference. The ZL-1 cam eats plugs, so I change them offen.

If you're not after that "nostalgic" look, and are looking for a better plug than the AC, try an NGK...the NGK site says the standard plug is the BR5ES, which would be an R6918B-7 in a racing plug...someone might wanna double check those numbers, as I'm kinda in a rush this morning! |
