Looking to purchase an 02 sensor set for the exhaust system on my car. I have replaced stock with O/R X pipe and obviously have a SEL. Im told it makes the car run rich and starves h/p.Plus that damn light is annoying, and of course every idiot in my car says " hey man, you got a check engine light on! " So everybody, can a brother get some help locating and recommending a good set to purchase this weekend? Appreciate all the help!!
