Installing a larger Blow Off Valve with a larger venturi will help your vehicle correct any excess pressure being built against the turbo impeller blades, which could stop the turbo from spinning. This is known as a Compressor Surge, and if this is eliminated, your turbo will spool faster, be more efficient and durable over time.
The Active Autowerke BOV system for the 335i and E60 535i is designed to exceed the performance of the turbo in stock AND upgraded power levels. This is the SAME valve you might have seen used on the mighty AA E36 600+ HP turbos and AA 500+ HP E46 M3 supercharger system. This system is a tried, true, tested unit that has withstood the rigors of boosts 20+ PSI.
Not only will this BOV system give you added protection of any compressor surge your BMW will have, especially with increased boost levels as used on AA's performance package. It has a uniquely designed venturi that will properly vent off the boost spike while delivering a nice sound.
This one-of-a-kind plug and play ""fit everytime with accuracy"" engineered parts will provide that finished factory type look that Active Autowerke is known for.
Active Autowerke Blow Off Valve features:
- NO compressor surge
- Larger openings to handle MORE boost
- Larger all aluminum venturi design with factory style throttle clamp
- A larger, single displacement Blow Off Valve that replaces the two smaller plastic valves.
