Product Description

The Turbosmart TS-0215-1022 Smart Port Dual Port Blow Off Valve is engineered as a direct upgrade for Mitsubishi Lancer Evolution IV through Evolution X models. This advanced hybrid valve combines both recirculating and vent-to-atmosphere functionality in one unit, allowing drivers to maintain smooth factory drivability while still achieving the aggressive blow-off valve sound desired in performance builds. It is designed as a direct replacement for the factory bypass valve and can support both stock and heavily modified turbocharged setups. :contentReference[oaicite:0]{index=0}

Turbosmart's Smart Port technology uses a staged dual-port design with a one-way valve integrated into the trumpet outlet. This system helps prevent engine stalling and significantly reduces the likelihood of compressor surge during throttle lift while maintaining compatibility with factory engine management systems. The lightweight aerospace-alloy piston with MILSPEC coating ensures rapid response, excellent sealing, and long-term durability even under high boost conditions.

Constructed from CNC-machined billet aluminum and finished with a durable anodized coating, the TS-0215-1022 is built for performance reliability in demanding street and motorsport applications. Installation is straightforward using the factory mounting location on compatible Evolution models, making it a popular upgrade for enthusiasts seeking improved turbo response, durability, and the distinctive blow-off valve sound.
