{"product_id":"recirculating-bypass-valve-2","title":"Recirculating Bypass Valve","description":"The GrimmSpeed V2 Bypass Valve, finished in black, is engineered as a direct replacement for the factory recirculating bypass valve on 2004-2021 Subaru STI and 2002-2007 WRX models. While the stock bypass valve is sufficient for OEM boost levels, it can become a limitation or fail when boost pressure increases due to modifications. This performance unit provides a more robust solution.\n\nDesigned to vent boost pressure back into the intake tract, the GrimmSpeed V2 bypass valve ensures more consistent valve response across a wider range of boost pressures compared to the OEM valve. This recirculating design is crucial for maintaining proper MAF sensor readings and avoiding fuel trim issues that can arise with atmospheric bypass valves on MAF-based fuel injection systems. It effectively prevents compressor surge and protects the turbocharger by managing boost pressure when the throttle is closed.\n\nThe valve comes with necessary installation hardware. GrimmSpeed, based in Portland, Oregon, has been developing performance parts for Subaru vehicles since 2003, focusing on real-world application and rigorous testing to ensure quality and correct fitment.","brand":"Subaru","offers":[{"title":"Default Title","offer_id":52689404920120,"sku":"GRM126032BLK","price":254.15,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687700749.webp?v=1784906299","url":"https:\/\/store.motormia.co\/products\/recirculating-bypass-valve-2","provider":"MOTORMIA","version":"1.0","type":"link"}
