Low Temperature Thermostat Kit For BMW N54 N55 With Sport Oil Cooler Valve, Aviation-Grade Aluminum
Upgrade your BMW’s cooling efficiency with the BMW N54/N55 Low Temperature Thermostat Parts featuring a Sport Oil Cooler Valve. Crafted from aviation-grade aluminum and finished with a corrosion-resistant anodized coating, this part is designed to lower engine oil temperatures under demanding driving conditions—delivering consistent high-performance results on track days or hot-weather sessions. By maintaining cooler oil, it helps preserve oil viscosity, reduce wear, and sustain power output when the engine is under heavy load.
Designed specifically for performance-oriented BMW builds, this low temperature thermostat works with a broad range of N54 and N55 engines and is compatible with the following models and years: 2008–2013 E82 135i / 1M N54 / N52; 2008–2013 E88 135i N54 / N55; 2008–2011 E90 335i / 335xi N54 / N55; 2008–2011 E91 335i / 335xi; 2008–2013 E92 335i / 335xi; 2008–2013 E93 335i / 335xi; 2008–2009 E60 535i / 535xi; 2008–2009 E61 535i / 535xi; 2012+ F2X F3X M135i / M235i / 335i / 435i; 2012+ F1X N55 535i / 640i (lt must be equipped with oil cooler).
What makes this thermostat part stand out is its precise low-temperature control combined with a dedicated sport oil cooler valve. This means more stable oil temperatures during spirited driving, less heat soak, and better protection for your engine’s bearings and turbochargers. It’s a smart upgrade for enthusiasts who push their BMWs beyond daily driving and who demand repeatable performance on the track without compromising reliability.
