Description CSF 8372 Engine Oil Cooler for BMW M240i (G42) / M340i (G20 / G21) / M440i (G22 / G23 / G26)

When designing this new cooler, CSF wanted to ensure the best possible performance with factory like fitment. This oil cooler is a truly unique design using CSF’s AC Condenser Technology. The 1-Row Super-High Pressure 32mm 10-Channel Microtube provides optimal oil flow and maximum surface area contact.

The CSF Oil Cooler utilizes a Super-High Pressure Microtube core which offers superior cooling performance over the traditional tube and fin design of the OE unit. The core volume was increased by 14% by increasing the core thickness from 28mm to 32mm.
