Spark Plug

#1
I read that the Spark Plug, AR3910X Racing pluga larger spark plug works great in Honda 160s..and can increase compression and HP....Anyone ever used this...was worried about piston clearance.... AR3910X_Clone_Plug.JPG

Yes we run this plug in our racing go karts, as far as compression maybe a tiny bit...and I always run two spark plug washers under it instead of one.

increasing compression? ...AND horsepower? ...It is a miracle plug! A miracle! You should have kept this a tightly held secret...the competition never would have suspected!
