{"product_id":"n54-n55-oil-thermostat","title":"N54\/N55 Oil Thermostat","description":"The Mosselman Oil Thermostat is engineered to enhance the reliability and performance of BMW N54 and N55 engines by managing oil temperatures more effectively. Constructed from a solid block of high-grade aluminum, this thermostat utilizes a true thermostat mechanism, ensuring optimal oil temperature regulation in both hot and cold climates, unlike \"always open\" solutions. It is specifically recommended for sporty street driving and tuned vehicles where stable oil temperatures are crucial for engine longevity and consistent performance.\n\nThe unit is designed for a plug-and-play installation, typically completed within 30 minutes. The housing is CNC machined for durability. This thermostat opens at a lower temperature (85°C) compared to the stock unit (which reaches around 120°C during normal driving), helping to maintain oil temperatures between 95°C and 105°C. For more demanding applications like track use, Mosselman also offers dedicated oil cooler kits for compatible models.\n\nCompatibility is extensive, covering various BMW 1-Series (E8x), 3-Series (E90\/E91\/E92), and Z4 (E89) models with N54 engines. Notably, for certain BMW 135i and 335i models equipped with the N55 engine, the Mosselman N54 Oil Thermostat is specified as the correct fitment, as indicated in the technical details. An installation kit, including O-rings and a gasket, is strongly recommended for a secure and leak-free installation.","brand":"Mosselman","offers":[{"title":"Default Title","offer_id":52663030120760,"sku":"MSL-E-Series-N54-N55-Oil-Thermostat","price":319.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0970\/4895\/3144\/files\/687076523.jpg?v=1784323013","url":"https:\/\/store.motormia.co\/products\/n54-n55-oil-thermostat","provider":"MOTORMIA","version":"1.0","type":"link"}
