AR#3910X Autolite Racing Plug

I run this on my fairly stock 5.5 Honda.... A member here told me they run it on their racing karts... I find a snappier acceleration and improvement thru low to high end...no lag..Highly recommend... LW

Can I run it on my HF predator 212cc?

IMO they're not that great of a plug. The only reason I see to use them is in karting where you're racing in a restricted class. The plug takes up ever so much more volume in the chamber and allows you to get a slightly higher compression ratio. But on a mini bike or anything where you're not restricted I just like a single electrode plug. Ngk bp6es is a good plug, same heat range just with no resistor in the plug.

I agree. I like the NGK's. Much easier to read and tune IMHO...
