Description

The ZZP M90 Billet Bypass Valve is engineered to enhance both the look and function of your M90 supercharged vehicle's engine bay. Crafted from durable billet aluminum, it boasts a serviceable and replaceable diaphragm, ensuring consistent and reliable boost holding capabilities for worry-free operation. This bypass valve, also known as a bypass actuator, offers a modular design allowing its housing to be rotated to accommodate various setups. The assembly includes etched billet housing, stainless steel hardware, and a powder-coated aluminum bracket for a premium finish. Installation is straightforward, with the valve including 1/4" vacuum hose and zip ties for completion. The ZZP M90 Billet Bypass Valve is designed to fit Gen 3 and Gen 5 M90 superchargers. Specifically, it is compatible with the following vehicles: 97-08 Pontiac Grand Prix, 97-04 Buick Regal GS, 04-05 Chevy Monte Carlo SS, 04-05 Chevy Impala SS, 96-03 Pontiac Bonneville SSEi, and 95-99 Buick Riviera. A fitment note for Gen 5 superchargers indicates that clearance can be tight, especially with an intercooler; the cap can be rotated if needed to address hood clearance concerns.
