Aluminum Engine Oil Cooler Adapter, Oil Filter Cover Cap for BMW E46 E36 E39 E60 E61 323i-530i M52 M54
Upgrade your BMW’s oil cooling capabilities with the Aluminum Engine Oil Cooler Adapter, a precision CNC‑machined solution that threads into the oil filter housing to route oil through an external cooler. Designed for M52/M54/M56 engines and compatible with a wide range of E36, E46, E39, E60, E61, X3, X5, Z3, and Z4 models, this adapter helps maintain optimal oil temperatures under demanding driving conditions—reducing heat soak during spirited driving, heavy city traffic, or hot weather. No need to replace the entire oil filter housing; simply install the adapter and connect external cooler lines for better lubrication and engine reliability. A built‑in sealing mechanism directs oil through the cooler lines and back through the oil filter, promoting consistent oil flow and protection for your engine components.
Lightweight yet durable, the adapter is made from high‑quality aluminum alloy with a corrosion‑resistant anodized finish. It features a versatile multi‑connector setup (AN10 fittings and two 1/8" NPT ports) to accommodate additional sensors such as oil temperature and pressure, giving you actionable insights into your engine’s health. Installation is straightforward, with the goal of lowering engine bay oil temperatures while preserving the original oil filtration system. Note that a small modification is required on some installations—sand the intake manifold slightly to ensure a clean fit. All electronic and mechanical equipment, devices and machines sold by InterCyprus to EU countries are CE certified and carry a two year warranty.
