I was told that the 12a engine runs better with a racing motorcycle sparkplug. the person didnt know the part # but said it was from a Ninja. fact or not?????

I'd be afraid to run the wrong plug if it's too long you could hammer an apex seal with that plug.

It won't run better unless you're running a turbo without an msd box or better ignition. The plugs that work are B8EG and B9EG. I've used them on my turbo 12a, gapped down to .010. They work good, but foul out kinda easy.

Ahh I have heard of running those NGK's, didn't know they were motorcycle plugs.

I have used the NGK BR10EIX plugs before and they run really well. That is in turbo 350+hp 13B applications. Is your setup fairly stock?
