Which Spark Plugs in Pro Topline 200cc Aluminum Heads?
I found some useful info in this post: https://www.thirdgen.org/techbb2/sho...13&perpage=75, but I was wondering if I could get some more direct answers. I am running the NGK equivelent of Champion C59C, and they seem like awfully cold plugs. Thanks!

There recomendations are for a starting point on a race motor.
these plugs are a little too cool for a street motor.
for a performance street/ strip motor I'd go with a
Champion RC12YC (NGK BCPR5ES)
