Aluminum AN10 Oil Cooler Adapter Kit for BMW E36 E46 E90 E92 335i M3

Keep your engine temperature stable under heavy load with the Aluminum AN10 Oil Cooler Adapter Kit, designed for select BMW models. You can easily route oil to an external cooler setup, adding vital cooling capacity for track sessions, aggressive street driving, or modified platforms requiring extra headroom.

This kit attaches directly to the Euro-spec oil filter housing found on compatible BMWs, allowing a clean upgrade without altering factory mounting structures. You gain access to precise -10AN ports and sturdy CNC-machined fittings that handle oil pressure fluctuations reliably. The built-in tie-down plate anchors your lines securely, minimizing vibration and protecting hoses over time.

Crafted from high-strength 6061 aluminum and finished with a protective black coating, this adapter resists corrosion while looking sharp in the engine bay. The package comes with two OEM BMW O-rings, enabling a leak-free seal using manufacturer-proven hardware.
