Get some NGK TR55's and gap them at or about .54 and you will love them.

I got the NGK. There alreay pregaped. Where did you get the horsepower increase from,seems kind of high. I heard 4 horse max,if that. Cost me $8 bucks a plug

Will I need a gapping tool for the NGK plugs or do they come gapped already.
