Oil Cooler

BMWs use an external oil cooler to regulate the temperature of engine oil and prevent a breakdown in viscosity and lubrication characteristics. If yours has suffered damage or developed a slight leak, make sure to replace it and keep the engine oil where it is supposed to be. Keeping this system properly serviced will significantly improve performance and increase engine life.

Whether your S55-equipped BMW serves as a daily driver or track car, keeping temperatures cool is critical. While most enthusiasts focus on upgrading the radiator and water-to-air intercooler systems, the engine oil cooler is an overlooked yet critical component.

New for the F8X-generation M2, M3, and M4 is a low-slung, horizontally mounted oil cooler designed to harness underbody aerodynamics. By placing the cooler in a low-pressure zone, this design enhances airflow efficiency and achieves sustainable oil temperatures for stock and street-driven cars. However, the compact core is quickly overwhelmed on modified or track-driven vehicles. Its exposed mounting position also leaves it highly susceptible to impact damage, so a minor scrape or piece of road debris can mean a costly full replacement. If you’re already replacing your oil cooler, it’s the perfect time to upgrade!

Our engineering team set out to solve the shortcomings of the factory design by developing a larger, higher-capacity core that delivers measurable gains in thermal stability. With a 7% increase in core thickness over OEM, this upgraded unit enhances airflow through the cooler and helps maintain lower, more consistent oil temperatures under sustained load. Thanks to its robust bar-and-plate core, precision-formed sheet metal end tanks, and durable 5052 aluminum construction, it’s built to withstand the harsh realities of real-world performance driving.

Replaces OEM part numbers 17212284540 and 17214802333.

Features:

High-efficiency bar-and-plate core for superior heat dissipation Fully TIG-welded 5052 aluminum end tanks Retains OEM rubber mounting for vibration-isolated, factory-style fitment Black painted finish with laser-etched Turner logo Designed as a direct-fit replacement and upgrade for S55-equipped F8X vehicles Design:

7% thicker core (30mm vs 28mm) for increased thermal capacity 6.5% increase in finned area (104,000 mm² vs 97,650 mm²) for better cooling Compatible with the Turner Motorsport skid plate kit (ES#3448772, ES#3247792) for complete protection Product Development:

Our High Performance Aluminum Heat Exchanger was designed, engineered, tested, and quality inspected by our Research and Development team in our Wadsworth, Ohio, facility. We strive for 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.

Made in the USA 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.

NEW REVISED Kit fits E36 Euro oil filter housing, E36 Euro oil cooler, E46 M3 stock oil filter housing, E46 M3 stock oil cooler , and works great with aftermarket oil coolers.

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.

Features & Benefits:

Forward-angled leading edge: Deflects road debris before it can reach critical components Rear-facing flared air channel: Ensures efficient ventilation and heat dissipation Heavy-duty 5052 aluminum construction: Tougher than stock, lightweight design Premium Wrinkle Black Powdercoat: Provides a resilient, yet brilliant-looking finish Optimized airflow channels: Keeps your oil cooler running at peak efficiency Reinforced protection: Shields vital engine components from road debris Factory mounting points: 100% bolt-on or off, no modifications needed Made in the USA: Engineered for quality and durability Kit Includes:

Turner Motorsport Aluminum Skid Plate – Wrinkle Black Hex Bolts (2) – SN5x35mm C-Clip Inserts (2) 6mm Skid Plate Spacers (2) Installation & Support:

For your convenience, we've provided a step-by-step installation guide, including detailed removal instructions, bolt locations, and torque values.

Made in the USA The TMS E36 Stage 2 Oil Cooler Line Upgrade Kit is an ideal alternative to the factory oil cooler lines, with multiple added benefits. In combination with our TMS AN-10 Oil Line Adaptor Kit (Part # TEN9910200), installing the TMS E36 Stage 2 Oil Cooler Line Upgrade saves you time and money. Unlike factory lines, the TMS E36 Stage 2 Oil Cooler Line Upgrade can work with vehicles equipped with superchargers or racing alternator pulleys. The TMS oil cooler lines now sit safely away from any moving parts like pulleys and serpentine belts. Our lines are made from HTP (High Temperature Polymer Braided), a synthetic line with multiple advantages over rubber or stainless lines.

We picked HTP lines for four reasons:
1) it insulates the oil from heat better than rubber or stainless lines,
2) the hose can hold a tighter bend radius without crimping or restricting oil flow, which makes routing the oil lines easier and more versatile,
3) the HTP line are less abrasive than stainless steel braided lines so they won�t rub through your factory power steering lines or any other rubber hose on the car,
4) weight savings � even if it is not much remember it all adds up.

Please Note, the following parts are required to install these lines:
� Euro oil filter housing
� Euro oil cooler and mounts
� (2) TMS AN-10 Oil Line Adaptor Kits (Part# TEN9910200)

BMW's N54 & N55 engines are very capable motors, but one drawback can be high oil temps. Even on vehicles with a factory oil cooler, oil temps can start to run away during extended track sessions or in very hot climates. This can lead to reduced horsepower, unintended engine and bearing wear, and even complete engine failure if not properly handled. ECS Tuning has an answer for just this problem, a Performance Oil Cooler Kit. This kit is easily installed behind the kidney grilles in addition to the stock cooler (located in the lower front bumper), receiving significantly higher amounts of fresh air and doubling the cooling capacity! Kit Includes: Oil Cooler Radiator Two Braided Oil Lines w/ AN Fittings Oil Distribution Block w/ AN Ports Distribution Block Mounting Bolt NOTE: Installation of the oil cooler radiator may require drilling out mounting holes depending on the selected location. Mounting hardware for the oil cooler is not included. Professional installation is recommended!
