What makes GFB better than the rest?

In the closed position, the piston in a GFB blow-off valve, seats against an acetal seal that means NO LEAKS under boost. All other valves rely on the diameter of the piston for sealing, and after a while the wear associated with the operation of the valve, increases the amount of air that leaks out. During operation the valve shuts rapidly and other brands use a circlip or metal seat which damage the soft brass piston as it smashes home. Soon after installation, the piston can become so severely damaged that brass flakes end up jamming the valve. GFB's acetal seat cushions the impact to protect the piston and ensure trouble-free operation.

GFB valves are physically smaller than the competition's, better suiting them to modern engine bays, whilst retaining the same high airflow characteristics.

Unlike others, GFB valves offer two different mounting options. They can either fit inside a variety of factory rubber hoses, or they can be mounted onto steel or alloy pipe.
