12 HP indigenous a collection of spark plugs? They need to turn air into nitous oxide or something! Too poor the bike & auto manufacturers haven\"t heard of this. If they could add 12 hp come their vehicle for chump change, they\"d be everywhere it, and we\"d every be getting an ext power turn off the show room floor! possibly that\"s how some that the sponsors that claim to get huge increases have the right to do it.I agree, Hammer.... Authorize ME UP!!! before everyone rather finds out!:cheers:
Autolite - 4163 is one chillier (.035 gap) . 114/117 on the dyno. Fires appropriate up every time w/cr\"s. Traction plugs twice to inspect color and nice and also clean with a straw corlor. Full cost much less than $4.
