The 295's are a little bit hotter plug which work much better in worn engines. Some folks use the 303's for Distributor fired Tractors. They work fine also providing the engine is pretty fresh, where oil control is in check and compression is up to the norm.

I've tried the NGK B6S plugs in my machines also. They worked quite well. No fouling, and burned pretty nice....

I goofed a b4 is the equivalent to a ac 45 or autolite 295 . the b6s is equivelent to the ac44 or autolite 303.
