Product Description

The Garrett 914956-0003 is a GVB-50A Vent to Atmosphere blow-off valve in Black, engineered by the same team behind Garrett's G-Series turbochargers and GVW wastegates. Built around a high-flowing 50mm valve, it's CFD tested for maximum flow and thermal efficiency, with a fully-machined billet housing and a 6061 anodized aluminum actuator cover for long-term durability under boost.

Designed as a direct, flange-compatible replacement for other major 50mm BOVs -- including TiAl 50mm/TiAl Q and Turbosmart units -- it's engineered to outflow those competitors while dropping straight into the same outlet with no drilling required. Replaceable internal components and a robust diaphragm design mean the valve can be serviced and rebuilt rather than replaced outright as it wears.

This is the Vent to Atmosphere configuration, releasing excess boost pressure to open air with the characteristic "whoosh" sound, rather than a recirculating setup. Not CARB legal -- not for sale or shipment to California. Backed by a 1-Year manufacturer warranty.
