Thanks for your anwers, the stock NGKs work fine, those Torque master (torquemaster.com) were offered but I wasn't sure, I read that there are no magical plugs to turn your 1990 Accord into a 2003 M3 LOL. What about K and N air filters? Do they worth the money? Also the same guy offered me some magical spark plug cables (magnecor I think, have you heard of them?) the ones I installed about a year ago are NGKs that matched (printing on the box) my car and they work O.K, any need to "upgrade"?
Thanks again!
