Turbosmart Smart Port BOV for Mitsubishi Evo 4–X

Firstly, Buy Turbosmart Smart Port BOV Mitsubishi Evo 4 5 6 7 8 9 X online. The Turbosmart Smart Port BOV for Mitsubishi Evo 4–X is a high-performance blow-off valve designed as a direct-fit replacement for the factory BOV on Mitsubishi Lancer Evolution models from Evo IV through Evo X. Part number TS-0215-1023, this black Smart Port Dual Port BOV combines precise CNC-machined construction, a lightweight aerospace-alloy piston, and staged airflow control to deliver fast valve response and reliable boost pressure management.

Unlike a conventional blow-off valve, the Smart Port uses a dual-port design that can operate as both a bypass and vent-to-atmosphere valve. This gives Evo owners flexibility when configuring their turbo and intake system. Turbosmart also designed the Smart Port trumpet to help reduce stalling and improve integration with factory engine mapping.

The result is a versatile BOV suitable for Evo enthusiasts who want a direct-fit upgrade that can support everything from a relatively stock setup to a heavily modified turbocharged build.

Turbosmart Smart Port BOV for Mitsubishi Evo 4–X

The Smart Port BOV is designed around Turbosmart’s Smart Port technology. Its lightweight piston and staged port design allow the valve to react quickly when the throttle closes and boost pressure needs to be released.

The Mitsubishi-specific version is engineered for the Evo IV through Evo X platform. This makes it an attractive option for owners working on classic CT9A and CP9A Evolution builds as well as the later CZ4A Evo X. Turbosmart specifically lists the product as a direct-fit upgrade for the factory BOV on Evo IV to X applications.

Smart Port Dual-Port Technology

Firstly, the Smart Port uses two staged ports to provide flexible airflow management. The valve can function as a bypass-style valve or vent to atmosphere, depending on the configuration.

A supplied port blanking plug allows the valve to be converted to a fully bypass configuration. This gives owners the ability to change the BOV setup without replacing the entire valve.

Lightweight Aerospace-Alloy Piston

Secondly, the Smart Port uses a lightweight aluminum piston with a military-spec coating. The reduced piston mass helps the valve react quickly while the coating is designed to improve durability and piston life.

This quick response is particularly useful on turbocharged Mitsubishi Evolution applications where maintaining proper boost control during throttle transitions is important.

CNC-Machined Billet Construction

Thirdly, the BOV features CNC-machined billet construction with an anodized finish. This gives the valve a strong, precise housing while also providing a clean performance appearance in the engine bay.

Turbosmart manufactures, assembles, and validates the product in-house at its headquarters.

Mitsubishi Evo Compatibility

The Turbosmart Smart Port BOV is designed specifically for Mitsubishi Evo IV through Evo X applications. Turbosmart lists it as a direct-fit upgrade for the factory BOV across this Evolution range.

This broad fitment makes the valve suitable for several generations of the Mitsubishi Lancer Evolution, including:

• Mitsubishi Lancer Evolution IV
• Mitsubishi Lancer Evolution V
• Mitsubishi Lancer Evolution VI
• Mitsubishi Lancer Evolution VII
• Mitsubishi Lancer Evolution VIII
• Mitsubishi Lancer Evolution IX
• Mitsubishi Lancer Evolution X

For earlier Evo models, the CP9A platform is commonly associated with Evo IV–VI, while later CT9A models cover Evo VII–IX and CZ4A identifies Evo X applications. Always verify the exact factory BOV mounting arrangement before installation, particularly on modified vehicles.

Benefits for Mitsubishi Evolution Builds

The Turbosmart Smart Port BOV provides several advantages for Evo owners upgrading their factory turbo system.

Fast valve response: The lightweight piston is designed to move quickly during throttle changes.

Flexible configuration: The dual-port design allows bypass and vent-to-atmosphere operation.

Direct-fit installation: The Mitsubishi-specific version is designed as a factory BOV replacement.

Strong construction: CNC-machined billet components provide a durable performance-oriented design.

Reduced risk of stalling: The Smart Port trumpet is designed to help prevent stalling during BOV operation.

Broad Evo compatibility: One application-specific valve covers Evo IV through Evo X.

The valve is therefore suitable for enthusiasts who want a performance BOV without moving to a generic universal valve and custom mounting arrangement.

Stock and Modified Turbo Applications

The Smart Port BOV is designed to handle applications ranging from stock vehicles to heavily modified Evo builds with upgraded turbochargers.

This makes it suitable for different stages of a Mitsubishi Evolution build. A stock or lightly modified car can benefit from the direct-fit design, while a higher-output turbo setup can take advantage of the valve’s performance-oriented construction and adjustable configuration.

However, BOV selection should always match the vehicle’s turbo system, intake configuration, boost level, and tuning strategy.

Installation and Included Components

The Mitsubishi-specific Smart Port BOV is designed for direct-fit installation in place of the factory valve. The package includes the BOV, port blanking plug, installed red spring, vacuum hose, clamps, and Turbosmart sticker.

Before installation, allow the engine and turbocharger to cool completely. Inspect the existing vacuum lines and mounting surfaces. After installation, check all connections carefully for leaks before driving the vehicle.

If you are converting from a factory recirculating setup to a vent-to-atmosphere configuration, consider the vehicle’s ECU calibration and airflow strategy before changing the BOV configuration.
