5.HOE said:no but my friends 03 cobra has them and the car runs fantastic, a tune shop told him to run em after he did a pulley swap so he wouldnt burn spark plugs. i do see what u mean about 5.0s running like shit with them every motor likes different things :dunno:
they told him that because he upped his boost, same as on my L now. I have NGK BR plugs because im running 17psi of boost >
