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\u003eBoth 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.\u003c\/p\u003e\n\u003ch3\u003eQuick Specs\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eCNC-Machined 6061 Aluminum \u003c\/li\u003e\n\u003cli\u003eCorrosion resistant anodized finish, available in both red and black \u003c\/li\u003e\n\u003cli\u003eOversized 38mm anodized aluminum piston for superior flow \u003c\/li\u003e\n\u003cli\u003eSwivel air fitting to aid in install and for accommodating custom setups\u003c\/li\u003e\n\u003cli\u003eNo tuning or adjustment required \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003e\u003cspan\u003eFitments:\u003c\/span\u003e\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cp\u003e15-21 Subaru WRX\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e14-18 Subaru Forester XT\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GrimmSpeed","offers":[{"title":"Default Title","offer_id":42401446166598,"sku":"GRM126033RED","price":372.99,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0250\/5929\/5280\/files\/1044022f90b576a8fb296b42ed78a9d2_0ef1ab49-7b90-485e-8ef7-1136af810d67.jpg?v=1735478207"}],"url":"https:\/\/subiesupplyco.ca\/collections\/grimmspeed-v2-bypass-valves.oembed","provider":"SUBIE SUPPLY CO.","version":"1.0","type":"link"}
