Engine Oil Cooler Adapter Aluminum for BMW E46-E61 M52/M54

Engine Oil Cooler Adapter Aluminum for BMW E46-E61 M52/M54

This lightweight, CNC‑machined aluminum oil cooler adapter is designed to let you add an external oil cooler to BMW M52, M54 and M56 engines without replacing the entire oil filter housing. Made in Mainland China, this adapter streamlines oil routing with a precision sealing mechanism that directs flow to cooler lines and through the filter, helping manage engine oil temperatures more effectively.

Key benefits include a reduction in engine oil temperature, improved oil circulation, and added flexibility for sensor integration. The adapter features two 1/8" NPT ports and two AN10 fittings, enabling easy installation of external sensors for oil temperature or pressure measurements. Its anodized aluminum surface combines durability with a clean, corrosion‑resistant finish.

Designed for broad BMW compatibility, it supports M52/M54/M56 engines across a wide range of models, including E46, E39, E60, E61, X3, X5, Z3 and Z4 variants such as 328i, 325i, 525i, and 530i. The product is optimized to lower oil temperatures and streamline installation, avoiding the need to modify or replace the entire oil filter housing.

Note: Only a small modification is required—sand the intake manifold a little bit for installation.
