The N54/N55 are the powerhouses of BMW, one of the most common tuning platforms, and a fan favorite for spirited driving. Being an N54/N55 owner you know that oil temps can get out of hand leaving you with an anxious feeling and the needle a little too close to the red on your gauge cluster. What if you could get the oil flowing faster, maintain lower temperatures, and still have proper engine warm-up?
Upgrade your N54/N55 engine with our Billet oil cooler housing, replacing the underperforming factory-cast aluminum unit. Engineered for enhanced performance and a blended aesthetic, our Turner oil cooler housing features an OEM+ black anodized finish and our own engineered lower-temperature thermostat. Unlike makeshift solutions like thermostat bypass kits, our housing integrates an OE thermostat, ensuring a gradual yet expedited engine warm-up process, similar to factory settings but faster.
Out goes the factory 110-degree Celsius (230F) thermostat, replaced by our 70-degree Celsius (158F) counterpart. This new thermostat triggers oil flow a significant 72 degrees Fahrenheit earlier than the factory version. This early flow translates into prolonged lower oil temperatures for both the oil cooler and engine, maintaining a happier, healthier engine with consistently lower operating temperatures.
For N54 owners seeking to use the full potential of their tuned or modified engines, our upgraded housing and thermostat are must-have additions, especially for those who frequent the track or enjoy spirited drives on winding roads. Even if you're not pushing your motor to its limits, this upgrade significantly enhances reliability. With rising oil temperatures, the risk of oil breakdown rises, resulting in compromised lubrication, more engine deposits, and increased wear over time. Our solution addresses these concerns, protecting your engine's longevity and performance, regardless of your driving style.
For vehicles equipped with the factory oil cooler, our housing offers a multitude of advantages and is a direct replacement for the OEM unit. If your vehicle lacks a factory oil cooler, this presents an ideal chance to upgrade your setup with our housing, enabling the addition of a factory cooler for enhanced performance and increased reliability. Our primary objective is to maintain optimal oil temperatures, ensuring proper lubrication for the engine's internal components, in turn prolonging their lifespan.
Features:
Thermostat - 40 degrees Celsius/ 72 degrees Fahrenheit lower than the factory unit Billet aluminum to replace the raw cast aluminum factory housing Optional cooler capability for cars without an OEM oil cooler Utilizes the lower temp thermostat to circulate oil sooner rather than an always open solution which inhibits warm-up Combine with OEM oil cooler to add cooling capacity to your FBO N54/N55 or replace the stock housing for a cooling upgrade using your existing cooler Replaceable thermostat and gaskets for easy maintenance Quick easy installation Kit Contents:

Upgrade your stock oil cooler thermostat for improved performance. Swap your factory 110-degree Celsius thermostat for a new 70-degree Celsius version for faster oil flow and extended temperature control. With oil temperatures reaching 230 degrees Fahrenheit by the time your factory thermostat opens, initiating oil flow at lower temperatures proves more effective than attempting to cool down already elevated temperatures.
Utilizing a factory-style thermostat, this upgrade can be used in all weather conditions and allows your engine to warm up properly, unlike thermostat bypass kits.
Kit contents:
Lower temperature thermostat - 70c (158F) vs Factory 110c (230F)
Low temp thermostat spring
