Turbonetics Twin Blow Off Valve Kit: BMW 335i
BMW owners have always understood the link between form and function. Just like the factories the vehicles come from aftermarket parts need to live up to design and performance. The Turbonetics 335i BOV kit surpasses both standards.

With higher boost comes added stress on the turbochargers rotating components. A well designed and efficient blow-off valve kit helps to alleviate unnecessary wear and strain on the turbochargers internal thrust bearings, turbine wheel shaft, increase lifespan and improve performance.

TiTek HKS Blow off Valve Kit : BMW 335i
The TitekUSA Blow-Off Valve kit has one goal, prevent compressor surge.

Compressor surge happens when the butterfly plate of a turbocharged engine closes and the remaining air is fed back into the turbocharger’s compressor housing creating resistance against the turbine. Compressor surge not only decreases the spool of a turbo but can also damage its center cartridge.

TitekUSA has designed this Blow-Off Valve kit for the BMW 335i in conjunction with the HKS SSQV (Super Sequential Blow Off Valve) to prevent compressor surge by venting the excess pressure when a throttle plate closes to improve spool-up and longevity while maintaing the OEM BMW Factory fit, quality, and finish.

cp-e Blowoff Valve Kit - BMW 335i
Custom Performance Engineering is excited with the release of its two different blowoff valve kits available for the BMW 335i coupe and sedan.

cp-e's first option utilizes made in the U.S.A. quality of the Tial Sport blowoff valve.  The adaptor features a unique throttle body fitting that is machined of 6061 T6 aluminum and seals against the throttle body using the stock o-ring gasket.  The Tial Sport blow off valve is a perfect match for the BMW, its sleek and sophisticated just like the car itself.  It offers a sound that is not obnoxious but loud enough that you know what is under the hood. 

The second option available is arguably the most popular, most common BOV in the world.  The kit has an optional, new and reworked SSQV from HKS.  cp-e™ is proud to offer a complete solution based on this valve.  The cp-e™ blowoff valve kit comes complete, with a high quality HKS "super sequential" blowoff valve, cp-e™ designed and manufactured adapter flange for the throttle body, and all of the hardware necessary to use this blowoff valve.

Both kits feature a 2.5" OD mandrel bent 6061 aluminum pipe and a billet 6061 aluminum MAP sensor mount to accommodate the stock MAP sensor.  cp-e™ also provides vacuum caps to cover the stock blow off valve nipples. The cp-e™ blow off valve adaptor is machined out of billet 6061-T6 Aluminum. cp-e™ uses a advanced 3D machining processes that most competitors will not spend the extra machine time on to bolt on to the stock throttle body.  Most BOV kits for this car involve cutting and hacking of the stock plastic components of the vehicle.

Blow off valves are a key component in any turbocharger system. When adding performance accessories to a turbocharged vehicle, a blowoff valve that is capable of dealing with the additional airflow and pressures should be selected. Aftermarket blowoff valves are designed specifically for larger quantities of air and higher pressures.

The BOV kit comes complete with all necessary hardware required for a complete and professional installation.

Active Autowerke Blow Off Valve - BMW E92 335i 07+
By installing a larger Blow Off Valve with a larger venturi, these components will help correct any excess pressure being built against the turbo impeller blades that can eventually stop the turbo from spinning. This is called Compressor Surge and when eliminated, the turbo will spool faster, be more efficient and durable over time.

All the hardware and fittings are designed to fit and function flawlessly even under high boost conditions. It has been tested and proven not to stall under any conditions. The only giveaway is that robust sound of the BOV when it vents to the outside atmosphere.

This BMW 335i blow off valve features:
- 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.

Fits: BMW 335i Turbo 2007+
