{"product_id":"grimmspeed-15-21-subaru-wrx-v2-bypass-valve-black","title":"GrimmSpeed 15-21 Subaru WRX V2 Bypass Valve - Black - GRM126033BLK","description":"\u003cdiv class=\"manufacturer-description\"\u003e\n  \u003cp\u003eWe started the ground-up design with the valve body and base for each popular fitment. Both are CNC-machined out of billet 6061 aluminum alloy for its strength and light-weight. They are then anodized in either a black or red finish to give them a brilliant appearance, provide corrosion resistance and match other GrimmSpeed offerings. Compared to the stock cast unit on the EJ STI and plastic construction on both the 08-14 and 15-21 WRX platforms, GrimmSpeed Bypass Valves not only stand out, but are guaranteed to stand the test of time. For the internal components of the valve, we chose to utilize a machined brass piston for its anti-corrosion and low thermal expansion characteristics. Our piston seats onto an internal O-ring to create a perfect seal, eliminating boost leaks common in OEM and cheap aftermarket BPVs . In order to make sure this could keep up with high power levels, we chose to use a massive 38mm diameter piston\/sealing ring for the ability to dump pressure quickly. This is especially important on high boost applications to keep the turbo from sustaining damage and the BPV maintaining leak-free operation. A precisely-tuned steel spring alleviates the need for any tuning or adjusting of the valve, with no engine tuning required to run the unit . Buna-N O-rings were the next logical choice due to their resistance to degradation from fuel and oil exposure. In addition, all of our O-ring grooves utilize a single dovetail design for superior retention. This guarantees the O-ring will not fall out and has the perfect crush for sealing the body together. To top things off, we employ a swivel fitting on the valve to make for easy installation and accommodate best-routing on custom setups. A GrimmSpeed signature branding badge graces the top of each unit so that everyone will know you chose the best valve in the biz. Both the 08-14 WRX\/05-09 LGT and 04-21 STI (EJ) fitments utilize the same valve but with different footprints for use across a broad range of vehicles including Legacys, Foresters and Bajas with the proper intercooler setup. The STI unit reuses the recirculating elbow from the factory BPV, ensuring precise alignment and a perfect fit. All this makes for a total plug-and-play package.
