Aluminum Turbo Blow Off Valve for Peugeot 308 1.6T, Mini R56/57 Cooper, and Citroën DS5

Upgrade your turbo setup with the Peugeot 308 Turbo Blow Off Valve Aluminum — a piston-based, all-aluminum BOV designed for Peugeot 308 1.6T, Mini R56/57 Cooper, and Citroen DS5. Built from durable aluminum alloy and engineered to outlast OEM diaphragms, this valve keeps boost control precise and engine response crisp under boost, while preserving ECU actuation for smooth drivability.

Main description

OEM solenoids often suffer from diaphragm failures that can split or bind, especially under heat cycling. When the diaphragm fails, the valve may not open fully or at all, leading to inconsistent boost control and potential risk to the turbo. This aftermarket valve solves those problems with a piston-based design that has no diaphragm to fail, paired with an all-aluminum construction for enhanced durability in demanding conditions. It replaces the original unit but continues to work with the OEM ECU to control valve actuation, maintaining familiar driveability while delivering improved reliability. The included high-temperature solenoid valve and plug-and-play wiring harness simplify installation, so you can get back on the road quickly. The spring is interchangeable to tailor boost response for daily driving or more spirited use, giving you precise control over how the valve responds to throttle input.

With a proven track record in high-performance contexts, this BOV emphasizes reliability and consistent performance under boost. By eliminating the diaphragm vulnerability and using a piston-driven mechanism, you reduce the risk of boost leaks or debris entering the turbo during maintenance. It’s a straightforward upgrade that delivers improved durability, stable boost behavior, and seamless integration with the car’s ECU for dependable, everyday driving or track-ready performance.

Benefits & Tips

• No diaphragm to fail: piston-based operation increases reliability in hot engine bays and reduces boost control issues.
