SPARK PLUG

Recommended Posts

stick to NGK. i think one or two people have tried a splitfire.

if you've ever fouled you can go to 7 but otherwise stick to the "cooking" model; CR8E

I run a twin electrode NGK in the 8 range with good results.

Easier starting and a slight improvement on the dyno as well.

It is a oem honda f-2 plug I believe.

I don't have the actual # off the top of my head, sorry.

try a CR8EK by NGK. they have a prong coming up on each side. More spark i guess. I could tell a difference. Anyone else use this kind.

I used one in my 400F but have not tried one in the 426 yet. I felt it made things a bit snappier(is that a word??) but did not notice any horsepower gain. I believe it is a good choice for a replacement.
