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+

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.

Forge Recirculation Valves - 335i N54 Twin Turbo
Developed specifically for BMWs all-new N54 twin turbo motor, as found in the BMW 135,335 and 535 models, Forge Motorsport adds another replacement valve application to our already extensive vehicle specific and universal valve lineup. While virtually identical in operation to the Bosch style valves as used from the factory on many other turbocharged applications, primarily Volkswagen and Audi, BMW has utilized a very different type of valve connection mechanism that makes their product and our replacement components very unique. Starting with the worlds best selling direct replacement Bosch style valve, our own 007P piston-based design, we have revised virtually every single component of the valve body, (except the internal piston), in order to retain BMWs unique connection mechanism yet offer improved functionality in every other possible way. The entire valve assembly is precision CNC machined from T6-6061 billet aluminum alloy on our very own Mazak CNC milling machines. Again, the valve is an aluminum piston based design, offering significantly improved reliability over the failure prone OEM diaphragm valves, yet with no change to valve response time. We utilize ultra high temperature Viton brand silicone o-rings for sealing and Mobil1 fully synthetic bearing grease for lubrication. The valves are fully tunable for both boost holding capacity and response by way of proprietary interchangeable springs and shims (washers to marginally adjust preload). By utilizing this method of valve tuning with multiple custom spring rates, the valves will retain the maximum range of piston travel and flow volume regardless of which spring rate is used. Valves with a singular spring requiring that adjustments be made by continually adding preload will suffer from decreased piston or diaphragm travel as the spring tension is increased. Though these types of valves may hold high boost levels under load, they will actually suffer from limited flow volume at throttle lift when the valve vents. The hoses included in the kit are a custom made multi-layer fabric reinforced flexible silicone hose that are designed to allow compatibility with the stock airbox and charge piping setup without any permanent modification being required to adapt our replacement valves. Even the included hose clamps are overkill. They are specifically designed for use with silicone hoses, utilizing a beveled band edge and a pressed in drive mechanism rather than perforated. They are even approved by NATO for international military use. All told, this direct replacement valve kit will be suitable for a bone stock car to one that is heavily modified. They can be installed on the car right on the showroom floor and they will last well past having upgraded your intake, exhaust, and ECU software. They are capable of handling an infinitely wider range of boost pressure, more reliably, than the OEM valves, and they carry an unlimited lifetime warranty and money back guarantee.
