{"product_id":"direct-fit-piston-recirculation-valve","title":"Direct Fit Piston Recirculation Valve","description":"The Forge Motorsport Direct Fit Piston Recirculation Valve is engineered as a direct replacement for your vehicle's original unit. This piston-based design offers enhanced longevity compared to OEM diaphragm valves, ensuring a more durable solution for your air and fuel system.\n\nConstructed with a full billet aluminum body and utilizing Viton high-temperature silicone o-rings for sealing, this valve is built for performance and reliability. It is lubricated with Mobil1 fully synthetic bearing grease and features a proprietary spring rate that can be tuned with optional spring kits to match increased boost pressures or engine modifications. The low-profile cap includes a 360-degree swiveling vacuum nipple for easier installation and allows for quick servicing without removing the valve from the vehicle.\n\nThis valve is supplied with an uprated yellow spring, and a tuning spring kit is available separately if further customization is desired. Please note that for Porsche 997 Generation 1 models, two FMDVK04S valves are required.","brand":"Forge Motorsport","offers":[{"title":"Default Title","offer_id":52688427548984,"sku":"FMDVK04S-C","price":188.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687900358.jpg?v=1784889995","url":"https:\/\/store.motormia.co\/products\/direct-fit-piston-recirculation-valve","provider":"MOTORMIA","version":"1.0","type":"link"}
