Re: Spark Plugs and Wires for Performance Inc.?
Keep in mind there are 12 plugs on these babies. I'm also skeptical that just plugs and wires will increase hp by 10. The manufacturers usually optimize that combination and unless yours are real worn or in poor shape, I cannot believe that much difference. But if they look cool and you need (or want) them, knock yourself out. PS - Same for K&N. I noticed a tad better gas mileage but no noticeable performance increase. The risk is dirtier air but the benefit is a "forever" air filter.
