Description

Designed for high-flow and performance, Granatelli Motor Sports' ultra-high-flow blow-off valves feature a 50mm design, compact size, and lightweight construction. These pressure release systems help take the load off your turbocharger when the throttle is suddenly closed, thus, reducing the risk of damage to both the turbo and your engine. They're adjustable, making them ideal for most boosted applications. These BOVs are precision machined from aluminum and black anodized for added durability, and include the vacuum fittings, aluminum weld flange, V-band assembly, and the springs.
