CSF Aluminium Heat Exchanger Upgrade for BMW G20 G21 320i 330i M340i, BMW G29 Z4 20i 30i M40i, Toyota GR Supra A90 A91
Unlock consistent, repeatable power with the CSF aluminium heat exchanger upgrade for BMW G20 G21 3 Series, BMW G29 Z4, and Toyota GR Supra A90 A91. This front mount heat exchanger is the essential cooling upgrade for tuned cars running Stage 1, Stage 2, or big-turbo Stage 3 software. By keeping intake air temperatures low and stable, it helps prevent heat soak, protects performance, and sustains power on the road, track, and drag strip.
When boost increases, so does heat. The factory heat exchanger and charge cooler can struggle, causing the ECU to pull timing and reduce boost. CSF’s larger, more efficient core significantly improves coolant cooling before it reaches the charge cooler, delivering a typical 5 to 15°C reduction in charge temps depending on tune and use. The result is stronger, more reliable performance with faster heat soak recovery and improved airflow through the rest of the cooling stack.
We’ve installed this CSF heat exchanger on customer cars and our own builds at Nforcd and the results speak for themselves: lower IATs, better consistency, and happier drivers. It’s a true drop-in, OEM-style upgrade built to take hard road miles and track abuse.
