Maximize your BMW 135i, 335i, or 1M's performance with the Active Autowerke Blow-Off Valve (BOV) Kit, engineered for N54 engines. This high-performance kit, featuring an integrated charge pipe, provides superior pressure management to prevent compressor surge and protect your turbocharger's compressor. It delivers the distinctive "whoosh" sound performance enthusiasts seek while enhancing engine reliability under high boost conditions. The BOV kit is built to handle elevated boost levels, making it suitable for drivers pushing their vehicles to the limit. This unit is proven to support over 600 horsepower, with a maximum boost pressure capacity of 43psi. Construction includes a CNC-machined aluminum flange, a factory-style throttle clamp for easy installation, and a durable black powder-coated finish for longevity and a clean aesthetic. For optimal results and compatibility, it's recommended to pair this kit with Active Autowerke's performance software. A note for ECU flashing procedures advises ensuring a stable battery voltage with a charger and disabling laptop sleep settings for a smooth installation process. Applications are specifically for the BMW 135i (E82), BMW 335i (E9X), and BMW 1M (E82), all equipped with the N54 engine.
