About this part
Maximize your BMW 135i, 335i, or 1M's performance with the Active Autowerke Blow-Off Valve (BOV) Kit, specifically designed for N54 engines. This high-performance BOV kit with an integrated charge pipe offers superior pressure management, ensuring that excess pressure buildup doesn’t harm your turbo compressor.

Paired with Active Autowerke's performance software, this kit delivers an unmatched combination of power and reliability.
