Silver-coated aluminum die-cast body. Combines the ultimate in looks and durability in the engine compartment. Secondary valve main portion is made of die cast metal. Reliable operation with beautiful looking.Triple Fins set at the center of the funnel produces a dynamic and aggressive sound.

The Pull-Type valve operation offers more precise relief of excess boost and is compatible for a wider range of boost pressure compared to typical push-type blow off valves. Lift off the throttle, and the primary valve instantly opens, quickly discharging initial excess boost pressure.This valve combined with the Primary Valve from the sequential dual valve structure. Optimal blow-off operation from how to high boost ranges without leaking.
