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.

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 hole can be used 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.

Features:

• 6061-T6 billet machined body, anodized black for lasting protection and appearance
• Strategically positioned 4 chamber baffle system maximizes oil / air separation 
• Knurled and black anodized oil dipstick makes inspecting oil volume of reservoir clean and simple
• Sealed with a pre-installed viton O-Ring
• Includes 2.5mm allen key to remove baffle plates for cleaning
• 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
• Closed / recirculated design reduces oil ingestion and promotes cleaner emissions and odor-less operation
• Optional use drain hole (valve and hose sold separately, watch for our model specific drain kits!)

Elevate your custom installation with the ECS -10AN O-Ring Boss fitting, a crucial component that connects your ECS Tuning Catch Can to a 3/4" ID hose. This fitting simplifies your plumbing setup, ensuring a seamless solution.

Featuring a pre-installed Viton O-ring, this fitting is engineered for excellence, providing a leak-proof seal that resists the effects of oil and fuel exposure, guaranteeing long-term durability.

The 3/4" nipple is thoughtfully designed with barbs to secure hose position effectively, minimizing the risk of hose disconnection. Keep in mind that clamps and hoses are available for separate purchase. These fittings are sold individually, with most installations requiring a pair of them.

Meet modern emission regulations while preserving engine performance with the ECS Baffled Oil Catch Can. Designed for BMW and MINI vehicles, this system efficiently captures blow-by gases, preventing excessive oil vapor ingestion into the intake tract. The innovative 4-chamber baffle system maximizes oil/air separation, reducing carbon build-up and pollutants. Featuring a 1/4" drain fitting for easy maintenance, this catch can minimizes oil deposits, ensuring cleaner emissions and enhanced engine performance.

Key Benefits:

• Efficient 4-chamber baffle system for maximum oil/air separation
• Recirculated design reduces oil ingestion, promoting cleaner emissions
• Durable 6061-T6 billet machined body with anodized black finish for longevity
• Integrated dipstick and sealed reservoir for easy oil inspection and maintenance
• Serviceable design with removable baffle plates for cleaning
• Easy installation with customizable mounting options and leak-free fittings
• Engineered and manufactured in the USA for superior performance and durability
