{"product_id":"oil-pressure-relief-spring","title":"Oil Pressure Relief Spring","description":"This fitting connects to the cam housing oil inlet and features a precise 2.5mm orifice. It is engineered to replace the earlier, larger 6mm original orifice, effectively limiting the amount of oil fed to the camshaft boxes. By doing so, this restrictor fitting helps to increase oil pressure at critical areas such as the main bearings, rod bearings, and piston cooling nozzles, contributing to improved engine longevity and performance.\n\nUnlike original factory parts that were typically zinc-plated mild steel, this restrictor fitting is CNC machined from durable stainless steel. This manufacturing process ensures a superior fit and finish, with particular attention paid to the threads for a secure and reliable connection. Installation is described as very easy, and two of these fittings are required per car. The product comes with a Limited Lifetime Warranty.","brand":"Porsche Genuine Parts","offers":[{"title":"Default Title","offer_id":52663296393528,"sku":"901-105-361-03-OEM","price":22.5,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687526340.jpg?v=1784325721","url":"https:\/\/store.motormia.co\/products\/oil-pressure-relief-spring","provider":"MOTORMIA","version":"1.0","type":"link"}
