Oil Cooler

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:

Our upgraded oil cooler housing was designed, engineered, tested, and quality inspected by our Research and Development team at Turner. Nothing but the highest level of precision and quality through leading-edge product development technology including FARO laser scanning for reverse engineering and quality inspection, SolidWorks 3D CAD modeling, rapid prototyping utilizing our in-house 3D printer, and rigorous long-term product testing.

Rally Road Productions, Inc. is a team supported by a group of people with great abilities in their area of expertise. From the "web guy" and driving instructor friends, to owners of various machine shops, they have surrounded ourselves with people that can be trusted to create and manufacture quality products. This is the key to ensuring everything that they sell will perform as it was intended. The goal is to increase customer satisfaction and make the customization or performance enhancement of your vehicle a more enjoyable venture.

This oil cooler system is race tested and proven to outflow the euro M3 oil filter housing. Additionally, this particular system uses a sealing mechanism to direct the oil flow through the cooler lines and then through the oil filter.  Other cooler caps do not provide this seal and therefore the external oil coolers and lines act as a "balloon".  The lines and cooler are pressurized, but oil does not flow through them.  Flowing oil means it is being cooled and not just acting as an external reservoir.

Flow testing reveals that the oil cooler cap will outflow the Euro M3 Oil Filter Housing by more than 80% at the same, pressure, RPM, and oil temperature. In the upper RPM range, there is nearly a 100% improvement in flow from the RallyRoad oil cooler cap when compared to the Euro M3 oil filter housing.  This is a massive improvement over OE and is a worthwhile upgrade, especially in engines that see severe duty.

Features:

• -8AN o-ring ports to provide a leak free fitting without the use of Teflon tape or sealant used by other oil cooler caps.
• Viton o-rings are used throughout to maintain function and sealing in a high-temperature oil environment.
• Use of the stock filter cap bolt to reduce cost and simplify installation.
• An internal sealing mechanism to direct oil flow through the oil cooler and through the filter.
• 1/8" NPT side port for external oil pressure gauge.

Kit Includes:

• Oil filter cap with fittings
• Oil filter sealing ring
• BMW MANN Oil Filter and gasket

This part fits the following BMWs
1992-1999 E36 323i 325i 325is 328i 328is

This is the engine oil heat exchanger which is located behind the oil filter housing of the M57 engine. When this part fails it can cause oil contamination in the cooling system or worse. Generally, the seals will fail before the unit itself but if yours is bad, change it as soon as possible to avoid any further complications. This Genuine BMW replacement part comes with new mounting hardware and gasket to make the job stress free. 

When doing any sort of repair or maintenance there is no replacement for genuine factory parts. Turner Motorsport carries the Genuine BMW brand with pride and has the parts you need to complete your next project with confidence.
