Don’t get left behind or have to do cool down laps at the track. The CSF Dual-Pass Charge-Air-Cooler solves heat soak issues with the S55 engine in the M3/M4 [F80/F82/F83] (especially when combined with the CSF High Performance Heat Exchanger). For the track enthusiast this is a must have!

Designed using 3D Scanning and Computational Fluid Dynamics (CFD), the CSF Charge-Air-Cooler maximizes efficiency for intake temperature reduction. While this does help with power gains, it makes a huge difference in power consistency. No one wants to be down on power after driving hard for 3 minutes right? 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.
