CSF 8041 BMW E8x E9x Steering Oil Cooler Upgrade

Give your hydraulic steering system the cooling it deserves. The CSF 8041 all aluminium steering fluid cooler is a proven motorsport-grade heat exchanger for BMW E82 E88 128i and E90 E91 E92 E93 platforms including the M3. Ideal for track days, fast road builds and endurance use, this heavy duty cooler helps keep steering oil temperatures stable, curbs heat soak and protects pumps, lines and the rack from thermal stress.

We run this cooler on our own cars and have supplied it to many enthusiastic owners. Feedback is consistently positive. Sharper, repeatable steering feel lap after lap, dependable temperature control in summer traffic and long-term reliability are exactly what you can expect from CSF’s all aluminium construction and race-bred design.
