A must-have replacement for the leaky, slow responding, and plastic OEM blow off valve.\u003c\/p\u003e\u003cp\u003eThe PERRIN BPV cap features adjustable spring tension, which allows for an adjustment when the blow-off valve vents. A looser setting will make it act smooth and more like stock. Setting it harder will cause it to vent later and with significantly increased boost levels. This adjustment is important in maintaining the air within the boost system without reducing turbo response.\u003c\/p\u003e\u003cp\u003eThe unique design allows you to control the volume of air released when the blow-off valve vents. Adjusting the volume of air helps maintain the perfect amount of boost in your system during shifts without causing compressor surges. Venting too little can damage the turbo, venting too much air can make the throttle less responsive. This adjustment is independent of the relief pressure allowing for a totally customizable bypass valve.\u003c\/p\u003e\u003cp\u003eIncrease horsepower and torque without ECU recalibration or tune! This part is designed and tested to work safely on your vehicle without any tuning required! However, more power can be gained with proper ECU tuning! Confirm any tune or recalibration you add is specific for ALL modifications added to the vehicle.\u003c\/p\u003e\u003ch3\u003eIn the box\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e(1) PERRIN BPV\u003c\/li\u003e\n\u003cli\u003e(1) Plastic Connector\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Perrin Performance\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart number:\u003c\/strong\u003e PSP-TAC-615RD\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBoost Side Tube OD:\u003c\/strong\u003e 1.325\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eIntake Side Tube OD:\u003c\/strong\u003e 1.00\"\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Material:\u003c\/strong\u003e 6061 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBody Finish:\u003c\/strong\u003e Anodize Red\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Material:\u003c\/strong\u003e 6061 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePiston Finish:\u003c\/strong\u003e Anodize Clear\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSpring:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFlange:\u003c\/strong\u003e 6061 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap Material:\u003c\/strong\u003e 6061 Aluminum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCap Finish:\u003c\/strong\u003e Anodize Black\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Blow Off Valves\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Perrin Performance","offers":[{"title":"Default Title","offer_id":50333104996544,"sku":"PERPSP-TAC-615RD","price":330.82,"currency_code":"CAD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0762\/4772\/8320\/files\/psp-tac-615_06_whitex800.jpg?v=1790511143","url":"https:\/\/mapletorque.ca\/products\/perrin-15-21-subaru-wrx-14-18-forester-xt-bypass-blow-off-valve-red","provider":"MapleTorque","version":"1.0","type":"link"}
