Description
Take your Mini’s performance and sound to the next level with the Forge Motorsport FMDV50, a fully atmospheric blow-off valve built specifically for the latest 2.0L B48 turbocharged engine found in the 2025+ Mini Cooper S, Cooper C, and John Cooper Works (JCW) models.
Unlike the factory valve, which relies on a diaphragm that can degrade over time, the FMDV50 features a robust piston-based design for superior reliability and boost control. With heat-resistant Viton O-rings, Mobil1 synthetic lubrication, and full aluminum construction, this valve delivers improved durability and turbo response—ideal for both stock and tuned vehicles.
Installation is seamless thanks to a bespoke plug-and-play wiring harness and a reliable Pierburg solenoid, ensuring full compatibility with OEM ECU control and no check engine lights or fault codes. Whether you're driving spiritedly or upgrading your Mini for the track, this valve provides a crisp, unmistakable turbo “pshh” sound and high-performance operation.
