Frequently Asked Questions

This 34mm valve serves as a high-performance direct replacement for stock plastic valves on vehicles including the Mitsubishi Lancer Evolution series (Evo 1-10 with standard 34mm hose connections), Colt/Lancer Ralliart, 3000GT/GTO, Subaru Liberty/Legacy GT (MY09-current), and universal custom installations using 34mm ID boost hoses.

The Dual Port feature uses staged opening timing. Under light throttle and low vacuum drop, boost recirculates back into the intake air tract like an OEM valve to maintain engine smoothness and eliminate stalls. Under high boost acceleration, the second port vents excess charge pressure to the atmosphere, generating the classic blow-off valve sound.

Yes. The kit includes a dedicated port blanking plug. Screwing the blanking plug into the trumpet port configures the unit as a 100% recirculating bypass valve, whereas fitting it to the recirculation port converts it to a 100% vent-to-atmosphere valve.
