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.
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.

There are a few reason having a catch can is an upgrade for a vehicle, from a separator system that no longer works to one that was never there. Modern day emissions regulations require the use of a closed crankcase ventilation (PCV) system to recirculate combustion blow-by gases from the crankcase back in to the intake to be burned. Unfortunately, these blow by gases contain water vapor (which is a byproduct of combustion) and pick up oil mist from and the windage cloud and cam lubrication system as they travel through the crank case. Due to less than 100% effective air/oil separation in the stock PCV system, some oil mist and water vapor gets carried back to the intake tract and over time cause oil deposits and carbon buildup in the intake manifold, intake ports, and on the back of intake valves. All will eventually lead to poor performance and reduced fuel economy, and the presence oil mist can in the intake charge even increase the risk of engine damaging detonation.
With direct injected engines this problem becomes more prevalent, and the N54 in your 135i or 335i is no exception. We're seeing a lot of N54 powered cars with drivability and performance issues due to significant carbon buildup in the intake ports and backs of intake valves. The “factory fix” is a walnut blasting service that commonly needs performed every 30,000 to 70,000 miles. Don't be part of this statistic! Our shop recommends an oil catch can be installed in-line in the PCV system to help reduce the build-up of performance robbing deposits and greatly reduce the need for costly walnut blasting service and related repairs in the future.
The catch can utilizes a strategically designed 4 chamber baffle plate system engineered to create multiple changes in the direction of airflow to cause oil droplets to fall out of suspension, maximizing the efficiency of the PCV air/oil separation. A dipstick is integrated into the cap so you can monitor the oil level, and the can is easily serviced. At each oil change simply unscrew the canister and empty the trapped oil with your regular used oil. The Turner Motorsport Oil Catch Can is CNC machined from billet 6061-T6 aluminum and with a stealthy black anodized finish for lasting durability and appearance, and includes everything needed for an OEM-like fully reversible installation. Another feature the Turner catch can has is the ability to add on a drain kit so you no longer have to fumble around getting the fill can out of a tight space. The drain can be run down to the belly pan of your car so draining can be done at the same time you change your oil or anytime in between.

Features:
The Turner N55 oil catch can was designed with a strategically positioned 4 chamber baffle system with an added easy drain feature. The intent behind this design was to offer the most effective oil/air separation while being incredibly easy to maintain. The included drain kit allows you to route the drain hose to a mounted location near the belly pan of the vehicle making it convenient to empty at oil change intervals.

With forced induction, track use, and/or extended high RPM usage, these symptoms increase as the factory PCV system is overwhelmed, and a catch can becomes a must for your F3x N55.

Features:
Through experimentation and data acquired from our E36 World Challenge Touring Cars, it was discovered that in long corners and under heavy braking that there was an oil starvation problem in the M50 and M52 engines. This system was developed to keep oil in the sump and eliminate the starvation problem. After several iterations, further testing and data acquisition in the Touring Cars showed that this system eliminates the problem of oil starvation. This is a less expensive alternative to replacing the stock oil pan with the factory BMW M3 Lightweight oil pan, while still achieving the similar results.

Features:
When we designed this catch we wanted to have the most function options available, the best separation method, and the easiest to service. The Turner engineered catch cans offer a pre-setup design based ion desired flow direction, however this does not limit you to this flow. The inner baffle orientation can be easily adjusted to flow in both directions in case you decide to move this catch can to a different vehicle. A 4 chamber system baffle system inside the catch can was engineered to create multiple changes in the direction of airflow within the separator to cause oil droplets to fall out of suspension before exiting the catch can. Having a closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation.
Our catch can was also designed with the idea that the cans fill level can easily be checked with a top mounted dipstick and an optional use bottom drain hole. The drain system comes complete with a valve and hose to be mounted at a lower area of the vehicle so when you're doing an oil change you can drain the catch can.

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.
