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:

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.

Increase drivetrain rigidity and put that power to the ground! This industry-leading encapsulated design reduces NVH and prevents heat transfer.
From the factory, all BMW models are equipped with soft rubber or fluid-filled engine mounts. While these mounts perform well at isolating drivetrain vibrations, they are prone to degradation and allow for significant drivetrain movement. This often results in a loose-feeling driveline, missed shifts, and a generally disconnected driving feel.
To address these issues, We have developed a performance alternative. Constructed from 6061 Billet Aluminum, these mounts are built to last. While most performance drivetrain mounts feature solid or polyurethane-bonded aluminum construction, the engineers at Turner designed a unique four-piece design that disburses NVH (noise, vibration, and harshness). This multi-piece design offers the added benefit of serviceability. Additionally, encapsulating the polyurethane and adding a TecaPeek isolator prevents heat transfer to the insert, increasing the lifespan and durability of the mount.
Features & Benefits:
High-strength 6061 billet aluminum construction 80A Polyurethane provides a considerable increase over stock rubber durometer, eliminating excess deflection and ensuring drivetrain stiffness. Instead of the typical polyurethane-bonded aluminum construction, this mount is encapsulated to reduce NVH (noise, vibration, and harshness). Finished in black hard-coat anodized for a clean, durable, and corrosion-resistant finish. TecaPeek isolator reduces heat transfer from the engine to the mount insert, increasing the lifespan of the mount. A simple bolt-on design makes for an easy install Replace your worn-out factory engine mounts and experience increased drivetrain rigidity, reduced deflection, and more precise shifting. Our Turner Performance Polyurethane Engine Mount Set is designed for maximum durability and strength while maintaining the perfect balance between stiffness and comfort—the perfect choice for your high-horsepower BMW!
