BMW F82 M4 S55 3.0L

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.

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.

We've designed a permanent, high-performance replacement for the flawed OEM pan: a cast-aluminum, increased-capacity upgrade that enhances cooling and durability. Its all-aluminum construction provides a significant upgrade over the OE plastic pan, which is prone to cracking when impacted by road debris. Engineered for those who demand more from their vehicle, our design increases fluid capacity to promote superior cooling and help maintain optimal transmission temperatures, even in the most demanding conditions.

To ensure a leak-free seal, we engineered a heavy-duty Viton gasket specific to their transmission pan design. The Viton material provides exceptional reliability under high temperatures and resists deformation—a common failure point of the factory rubber gasket. For further protection, integrated magnets actively attract and hold metal debris that could otherwise compromise the transmission's longevity. This innovative design keeps your fluid clean and extends the overall life of your drivetrain.

Whether your DCT-equipped BMW serves as a track car or a highway cruiser, this pan ensures your transmission remains cool and efficient, minimizing the risk of overheating and wear.

BMWs turbocharged S55 engine uses a water-to-air charge air cooling system, with a front-mounted heat exchanger responsible for heat dissipation. Unfortunately, the factory single-row, 27mm core design is quick to heat soak under high load, leading to excessive intake air temperatures and potential limp mode conditions especially on modified or track-driven cars.

To solve this issue, we've developed a drop-in upgrade over the factory unit. Engineered for durability and maximum cooling efficiency, this heat exchanger is a must-have for high-horsepower street builds, spirited canyon driving, and extended track sessions. Built from TIG-welded 5052 aluminum, our design eliminates the factory plastic end tanks one of the systems most common failure points. Each heat exchanger features CNC-machined billet aluminum hose connections, mounting flanges, and brackets for perfect OE fitment and trouble-free installation.

By replacing the OEM 27mm single-row core with a robust 35mm dual-row design, this heat exchanger dramatically increases both cooling capacity and surface area. Frontal area jumps from 307mm to 475mm, resulting in a 100% increase in coolant volume and significantly improved heat-soak resistance. The outcome? Lower, more stable charge air temperatures that help your S55 deliver consistent, reliable power on the street or at the track.
