Huh?

I'd try some of the NGK racing plugs, they work great.
Go by any Napa auto parts store tell then what you have and what the intended purpose is and they will hook you up.
They run about $2 a pop, which is not bad for a racing plug.
Goodluck, Cp

NGK or Nippondenso. Last longer and fire better than any american plug. Why do you think the Jap's cars get better mileage.
