BMW M3 (2008-2013) E92 CSF Race-Spec Transmission / Oil Cooler

A Motorsport-Grade Cooling Solution for High-Performance BMWs

The CSF Race-Spec Transmission/Oil Cooler is the ultimate upgrade for BMWs that demand absolute reliability under heat and load. Engineered for the E9X M3, 335i and E8X 135i platforms, this cooler is designed to eliminate heat-soak, prevent temperature-induced limp modes and deliver sustained performance in both street and competitive environments.

Whether you’re running a naturally aspirated M3 or a high-boost N54/N55 turbo build, this cooler ensures your drivetrain stays protected where factory systems fall short — especially in Australian conditions.

Engineering Excellence

High-Efficiency Core Design

The cooler features a race-spec high-pressure micro-tube core with a 22 mm wide, 11-channel dual-pass layout. This design drastically improves fluid flow and cooling efficiency compared to standard OEM and aftermarket coolers.

Maximum Heat Dissipation

A multi-louvered fin stack increases surface area and airflow engagement, providing up to 30% greater heat rejection than stock. This allows the transmission or engine oil to maintain stable operating temperatures during extended high-RPM, high-load or track sessions.

Lightweight, Durable Construction

Crafted from high-quality aluminium and TIG-welded for longevity, the cooler offers exceptional strength while keeping added weight to a minimum. This makes it suitable for endurance use and repeated heat cycles.

Direct Bolt-On Fitment

The CSF cooler has been built with precise OEM geometry, allowing it to bolt up using factory brackets, ducts and hoses. No cutting, trimming or fabrication is required — an incredibly rare feature for a true race-spec cooling unit.

Performance Benefits

• Dramatic reduction in transmission or engine oil temperatures

• Prevents overheating, limp mode activation and fluid breakdown

• Protects bearings, clutch packs, gears and internal seals

• Enhances long-term drivetrain reliability for tuned and stock vehicles

• Essential for hard street driving, track days and hot-climate environments

The result is a more consistent, confident and durable performance platform — ready for anything from spirited mountain runs to hours of circuit use.
