I was wondering if its worth it to pay $50 for a K&N Air filter, buy those four pronged spark plugs, take of the chrome air filter... and hook up my ram air, and to buy 93 octain gas. Will all this stuff actually make a dif in how my car runs?
Yes it will, a big difference actually. But if your talking about the Bosch Platinum 4 spark plugs, dont get them. Theyre no good on American cars.
