Mosselman TWIN OIL COOLER EXTENSION KIT

The Mosselman TWIN OIL COOLER EXTENSION KIT is a game-changer for BMW 1-Series E8x and BMW 3-Series E9x owners looking to enhance their vehicle's cooling performance. Designed specifically for the E-series N54 and N55 engines, which are notorious for oil cooling issues, this kit ensures your engine stays cool, even under intense driving conditions. The twin cooler setup replaces the OEM cooler on the right side and adds an additional cooler on the left, providing comprehensive coverage and optimal cooling efficiency.

Advanced Cooling Solutions

This kit comes with premium components, including 2x Setrab 19-row oil coolers, pre-assembled stainless steel brackets, a complete mounting bracket for the left cooler, an oil adapter AN8, and a comprehensive hose kit (3 hoses). The twin cooler design not only increases the surface area for heat dissipation but also ensures that your engine oil maintains a stable temperature, prolonging its lifespan and enhancing overall performance. For the ultimate cooling experience, we strongly recommend combining this kit with the optional MSL Oil Thermostat, which is available for separate purchase.

Optimized for Performance and Daily Use

The Mosselman TWIN OIL COOLER EXTENSION KIT is ideal for both track and street use, offering superior cooling for tuners and enthusiasts who demand the best from their vehicles. The kit is not a simple "plug-and-play" solution, as it requires some adjustments to fit the larger oil cooler and bracket. However, the installation process, which takes approximately 4 hours, is well worth the effort for the significant performance gains it provides. Whether you're a 1M owner looking to optimize your vehicle's cooling system or a general BMW enthusiast, this kit is a must-have for anyone seeking to keep their engine running smoothly and efficiently.
