Don't get left behind or have to do cool down laps at the track. The CSF High Performance Heat Exchanger helps solve heat soak issues with the S55 engine in the M3/M4 [F80/F82/F83]. For the track enthusiast this is a must have!

The CSF Heat Exchanger features a 2-row 42mm dual core with CSF's exclusive B-Tube Technology. B-Tube Technology allows for over 15% increase in cooling efficiency over a tradition O-tube design.

Well, now you don't have to worry about that anymore! Also, this is a simple upgrade that does not involve custom installation so reverting back to stock later is easy to do if needed.
