Oil Cooler Adapter Kit for BMW E36 E46 E82 E9X 135/335 E46 M3 E90 E92

Upgrade your BMW’s cooling performance with the AN10 Oil Cooler Adapter Fitting Kit designed for BMW E36, E46, E82, and E9X platforms, including 135/335 variants and M3/335i lineups. Crafted from premium aluminum with a black finish, this CNC-machined kit makes it straightforward to route oil to a custom external cooler, helping you maintain optimal oil temperatures during street driving and track sessions alike.

Main Description

Designed for compatibility with a broad range of BMWs that use Euro oil housing configurations, this adapter kit enables -10AN oil lines to feed a dedicated oil cooler. The 6061 aluminum fittings and tie-down plate are precision-machined for a secure, leak-free connection, reducing downtime and maintenance headaches. By expanding oil-cooling capacity, the kit supports more demanding driving scenarios—whether you’re pushing a street setup, tracking laps, or running a forced-induction configuration that generates extra heat in the engine bay.

The kit is tailor-made for models that include the E36 with Euro oil filter housing, E46, E82, E9X 135/335, E46 M3, E90, and E92 ranges, including E93 convertibles and the later E82 135i 1M Coupe. It’s an ideal upgrade when you’re chasing better oil stability, more space in the engine bay for an oil accumulator, or room to add a supercharger setup while keeping oil temps in check. The included OEM BMW O-rings ensure a reliable seal, so you can focus on the road or the track rather than worrying about leaks.

All items are Brand New unless stated otherwise. We sell DIY (Do It Yourself) items with a few exceptions and take no responsibility for teaching installation. Professional installation is strongly recommended to ensure proper fitment and optimal performance. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty. For added peace of mind, this kit pairs well with stainless steel oil lines and one of our stacked-plate oil coolers for a complete, capable cooling system.

Benefits & Tips

• Maximize oil cooling under demanding conditions. This adapter kit makes it easier to route oil to a dedicated cooler, helping maintain consistent oil pressure and protection for high-load driving.
• Space optimization in the engine bay. By providing a compact, reliable route for oil lines, you’ll have more room for additional components like an oil accumulator or a supercharger setup.
• Easy upgrade path. Start with the adapter kit and compatible stainless lines, then add a high-capacity cooler to customize your cooling solution for your driving needs. Tighten O-rings and check for leaks after first startup.
