Product Description

The Turbosmart TS-0215-1023 Smart Port Dual Port Blow Off Valve is designed as a direct replacement for the factory bypass valve on Mitsubishi Lancer Evolution IV through Evolution X models. This advanced hybrid valve uses Turbosmart's Smart Port technology, combining a traditional recirculating bypass function with a vent-to-atmosphere outlet in a single unit. The staged dual-port system maintains smooth drivability and ECU compatibility while still producing the signature blow-off valve sound desired by performance enthusiasts. :contentReference[oaicite:0]{index=0}

The valve features a lightweight aerospace-alloy piston with a military-spec coating that provides rapid response, excellent boost sealing, and long service life. Its CNC-machined billet aluminum body ensures durability under high-boost conditions, making it suitable for both stock turbo setups and heavily modified vehicles with upgraded turbochargers.

Smart Port technology incorporates a two-stage port system with a one-way valve integrated into the trumpet outlet. This design helps prevent stalling and significantly reduces low-speed compressor surge while maintaining proper integration with the factory engine management system. Installation is straightforward using the factory mounting location on supported Mitsubishi Evolution and Ralliart models.
