As always the case with GrimmSpeed Products, we focus on\u003cstrong data-mce-fragment=\"1\"\u003e form AND function\u003c\/strong\u003e, and these units are no exception. We aimed to create an \u003cstrong data-mce-fragment=\"1\"\u003eextremely durable bypass valve\u003c\/strong\u003e that could hold double the pressure of the stock unit, while still being a stylish part that compliments the other GrimmSpeed Parts under your hood.\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eMaterial and Design\u003c\/h3\u003e\n\u003cp data-mce-fragment=\"1\"\u003e\u003cspan data-mce-fragment=\"1\"\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 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, \u003c\/span\u003e\u003cstrong data-mce-fragment=\"1\"\u003eGrimmSpeed Bypass Valves not only stand out, but are guaranteed to stand the test of time.\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eFor 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,\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003cstrong data-mce-fragment=\"1\"\u003eeliminating boost leaks common in OEM and cheap aftermarket BPVs\u003c\/strong\u003e. 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,\u003cspan data-mce-fragment=\"1\"\u003e \u003c\/span\u003e\u003cstrong data-mce-fragment=\"1\"\u003ewith no engine tuning required to run the unit\u003c\/strong\u003e. Buna-N O-rings were the next logical choice due to their resistance to degrading 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.\u003c\/p\u003e\n\u003cp data-mce-fragment=\"1\"\u003eWhen designing the 15-21 WRX (FA) unit we paid special attention to size. This was important due to a high number of hoses, wires and hard parts needing to pass through this same compact space. We were able to keep the same large 38mm piston, but slim down the footprint of the valve making working in that area easier than with the factory part. With the GrimmSpeed Bypass Valve installed, a definite \u003cstrong data-mce-fragment=\"1\"\u003ecrispness and sound change\u003c\/strong\u003e is noticeable through the intake and due to the leak free nature of our valve, the car builds boost much more quickly over the leak-prone OEM version.\u003c\/p\u003e\n\u003cul data-mce-fragment=\"1\"\u003e\u003c\/ul\u003e\n\n","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":39649402749024,"sku":"grm126032RED","price":259.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1398\/9853\/files\/GrimmSpeed-V2-Bypass-Valve-Subaru-STI-2004-2021-WRX-2002-2007-Red-126032RED.jpg?v=1743699305","url":"https:\/\/www.importimageracing.com\/products\/grimmspeed-v2-bypass-valve-subaru-sti-2004-2021-wrx-2002-2007-red-126032red","provider":"Import Image Racing","version":"1.0","type":"link"}
