The newest addition to Helix's product line is a must-have for old- and new-school turbo enthusiasts. Our blow-off valve kit sounds stock under normal driving coditions, but will add that traditional turbo 'whoosh' to your R56 when you're really jumping on it. The helix BOV helps prevent compressor surge and reduce exhaust gas temperatures. Due to superior design and extensive spring testing, the Helix BOV does not cause check engine lights or MAF related problems.

Helix's kit includes high-quality machined elements and installs in about an hour with normal hand tools. There is no cutting or drilling necessary.
