Chevrolet Cavalier Performance
RK Sport has everything you can imagine for Cavalier performance. NOPI also offers several things that will boost peak hp and torque.
Bear in mind, just about anything you do that's NOT RK Sport will trash your warranty. RK Sport is a GM subsidiary and their products don't affect the warranty when installed properly.
