08-14 WRX / 05-09 LGT V2 Bypass Valve

Here, you are looking at the all-new Grimmspeed V2 Bypass valve for your 2008-2014 WRX or 2005-2009 LGT. Please note, an aftermarket intercooler is required for this valve.

MATERIAL & DESIGN:

Grimmspeed designed the valve body and base for each fitment from billet 6061 aluminum alloy, then anodized them in black or red to match our other existing product offerings. Doing this provided corrosion resistance and a brilliant appearance. This second iteration of their Bypass Valves comes equipped with a massive 38mm diameter aluminum piston to quickly dump pressure, an important feature for maintaining leak-free operation and ensuring proper operation of a forced-induction platform. These valves include Buna-N O-rings for resistance abrasion and any fluids that may find themselves in your intake system. A swivel fitting accommodates custom setups and allows for easy installation.


FIT & PERFORMANCE:
Best of all, there is no tuning required for these bypass valves! With the GrimmSpeed Bypass Valve installed, there is a noticeable change in sound and crispness through the intake, and the car builds boost much more quickly than with the leak-prone OEM version. The STI unit reuses the recirculating elbow from the factory BPV, ensuring precise alignment and a perfect fit, making for a total plug-and-play package.

CHANGES MADE IN THE V2 BPV:

• Removed inspection port - this was primarily used for quality control, but it is not required with the new design.

• Redesigned the internal piston - eliminates the potential failure points seen in the V1 design.
• 
Adjusted tension of the internal spring -better suits the operating environments seen after further testing and development.

• Updated the design of the main body - better CnC milling finish.

• Exchanged the internal brass piston from V1 for a lighter weight hard aluminum piston - resulting in better valve response.

QUICK SPECS:

• CNC-Machined 6061 Aluminum

• Corrosion-resistant anodized finish, available in both red and black
• 
Oversized 38mm anodized aluminum piston for superior flow

• Swivel air fitting to aid in installation and for accommodating custom setups
• 
No tuning or adjustment required
