Description

Changing supercharger pulleys for more boost is a popular way to add more power to the '03 and '04 Cobra. What many people don't realize is that the factory supercharger system is designed to bleed off extra boost. The Steeda Boost Bypass kit maintains maximum boost during wide open throttle, to get the most power from the supercharger pulley upgrade. Installation is simple and only takes a few minutes.Product BenefitsMaximize boost during WOT (Wide Open Throttle)Instantly adds hp to your '03-'04 CobraSimple installation
