{"product_id":"piston-recirculation-valve","title":"Piston Recirculation Valve","description":"The Forge FMDVK04S-C is a direct replacement piston design recirculation valve, designed to be an upgrade over factory valves. This valve provides greater longevity than OEM diaphragm valves and can be tuned with different springs to accommodate engine modifications or increased boost levels. For ease of installation, the top or vacuum connection is angled.\n\nThis valve serves to release built-up air pressure when the throttle is released on a turbocharged car. Releasing this pressure quickly helps prevent the turbo from slowing down, thus reducing lag and ensuring a faster return to boost. The piston design is noted for its durability.\n\nService kits and spring tuning kits are available separately to allow for product servicing and customization. For Porsche 997 Generation 1 vehicles, two FMDVK04S valves are required.","brand":"Forge","offers":[{"title":"Default Title","offer_id":52688421585208,"sku":"FMDVK04S-C","price":34.39,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/662662200.jpg?v=1784889941","url":"https:\/\/store.motormia.co\/products\/piston-recirculation-valve","provider":"MOTORMIA","version":"1.0","type":"link"}
