NEW, updated design allows for more applications! The TMS Oil Cooler Fitting kit allows much more flexibility in the routing of oil cooler lines. Standard oil coolers utilize �hard lines� which can cause fitment issues for cars with superchargers, Accusumps, or other aftermarket performance parts. Our kit replaces the oil cooler hard lines with two TMS engineered -10 AN fittings, mounting bracket, and O-rings. Flexible braided hoses can then be run to the oil cooler which eliminates routing issues from supercharges, intakes, and other components. The brackets are CNC machined stainless steel and the -10 AN fittings are lightweight aluminum.

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

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:

BMW's newest high-performance powertrain—the S58B30—has proven to be an extremely durable platform built to last! Unfortunately, its factory oil cooler location is an egregious weak link in an otherwise bulletproof oiling system. Positioned just inches above the ground, the engine oil cooler is vulnerable to damage from debris, potholes, parking blocks, and other unavoidable road hazards. A single impact has the potential to rupture the cooler’s delicate aluminum fins and tubes, resulting in rapid oil loss and catastrophic low oil pressure. The only factory protection for this part is a flimsy undertray.
To safeguard the oil cooler, we've engineered a high-strength Aluminum Skid Plate for the F97 X3M and F98 X4M. Designed for peak performance and protection, our skid plate acts as a shield, preventing damage to the oil cooler while maintaining proper cooling efficiency.
Crafted from 4GA (4.83mm) 5052 aluminum, our skid plate delivers a perfect balance of strength and weight savings. Unlike the fragile factory plastic belly pan, our design forms a protective barrier from the front bumper to the front subframe, shielding your oil cooler and other fragile componentry from unexpected impacts. Its sturdy one-piece design enhances underbody rigidity without adding unnecessary weight over the front axle.
At Turner Motorsport, we believe protection shouldn't come at the cost of performance. Our engineers aimed to outperform the factory undertray design with laser-cut air channels that optimize airflow through the oil cooler. While located under the engine, the oil cooler receives its fresh airflow from the front air dam. Air flows through the lower front grille, into the oil cooler core, and out of the skid plate. The factory belly pan allows air to bypass the core, leading to inefficient cooling and mediocre airflow at speed. Our design allows for efficient heat dissipation by incorporating flared air channels, which guide cool air through the oil cooler and deflect road debris before it can reach the fragile core.
Upgrade your F97 X3M or F98 X4M with the Turner Motorsport Aluminum Skid Plate for added protection, durability, and performance.

Keep your S55 running cooler, longer. The factory oil cooler thermostat on the S55 waits until the oil reaches roughly 110°C (230°F) before sending it to the cooler. By then, the cooling system is already playing catch-up, especially on track days, spirited canyon runs, hot summer traffic, or tuned cars making well beyond stock power.
Our S55 Billet Oil Cooler Thermostat design addresses this issue at the source. Our proprietary low-temperature 70°C (158°F) thermostat routes oil through the cooler much earlier, so temperatures stay controlled before they climb instead of being pulled back down after the fact. The result is more consistent oil temperatures, more stable performance lap after lap, and less heat stress on bearings, turbochargers, and other critical components.
Unlike thermostat delete or “always open” bypass solutions, our kit uses a real working thermostat. Your engine still warms up properly on cold starts, which protects internal friction surfaces and keeps the oil at the right temperature for daily driving in any climate. Housing the thermostat is a CNC-machined billet aluminum cover, which is much stronger than the factory piece and looks great under the hood. Our thermostat solution is compatible with both factory and -10 AN oil cooler lines when used in conjunction with an AN Line Adapter (see T#59331100).
Heat is the enemy of lap times and engine longevity. BMW calibrated the factory oil thermostat on the N54, N55, and S55 platforms for rapid warm-up and emissions targets, running oil temperatures uncomfortably hot under prolonged load. When you’re pushing full throttle down the straight or stacking laps in midsummer, you need thermal headroom long before factory thresholds are reached.
The Turner Motorsport Oil Cooler Thermostat Housing drops your thermostat threshold to 70°C, circulating oil through the cooler early to build a buffer against heat saturation. Engineered for hard-driven road course and track day cars, the housing is protected with a Type III black hardcoat anodized finish for maximum resilience against thermal cycling and harsh track environments. Build flexibility is built right in: retain your OEM hard lines for a simple, direct-fit cooling upgrade, or adapt to full braided lines using our Turner AN Adapter for dedicated competition oiling systems.
