{"product_id":"thermostat-85-c-185-f-for-bmw-n54-n55-s55-engines","title":"Thermostat 85°C \/ 185°F for BMW N54\/N55\/S55 Engines","description":"The Mosselman Oil Thermostat is engineered to address common oil cooling issues found in BMW N54, N55, and S55 engines. Unlike a simple 'always open' solution, this thermostat features a real thermostat mechanism that opens at 85°C (185°F), significantly lower than the stock 105°C (220°F). This results in an operational oil temperature up to 20°C (68°F) cooler than OEM specifications, leading to more stable performance and enhanced engine reliability, especially for tuned vehicles and sporty street driving.\n\nConstructed from a solid block of high-grade aluminum and CNC machined at Mosselman's facility, this thermostat is designed for a plug-and-play installation that takes approximately 30 minutes. It uses a real thermostat, ensuring proper operation in both hot and cold climates and allowing the oil to reach its operating temperature efficiently. The kit includes the necessary gasket, O-rings, and titanium bolts for a complete installation.\n\nWhile recommended for sporty street driving, more demanding applications like track use may benefit from dedicated oil cooler kits, which Mosselman also offers for specific BMW models. This oil thermostat is a direct replacement and an excellent upgrade for drivers seeking to maintain optimal oil temperatures under performance driving conditions.","brand":"Mosselman","offers":[{"title":"Default Title","offer_id":52663031923000,"sku":"030210055","price":450.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687076511.png?v=1784323028","url":"https:\/\/store.motormia.co\/products\/thermostat-85-c-185-f-for-bmw-n54-n55-s55-engines","provider":"MOTORMIA","version":"1.0","type":"link"}
