CSF All Aluminium Heat Exchanger Upgrade for Toyota GR Supra A90 A91, BMW Z4 G29 and BMW 3 Series G20 G21
Upgrade the cooling system on your Toyota GR Supra A90 A91 or BMW B58/B48 powered G29 Z4 and G20/G21 3 Series with the CSF All Aluminium Heat Exchanger. This front mount heat exchanger is a direct, drop-in, plug and play solution that keeps intake air temperatures low and consistent on Stage 1, Stage 2 and big turbo Stage 3 builds. Perfect for fast road, track days and drag use where heat soak kills performance.
Heat is the enemy of power. Once you tune these cars and raise boost, the factory heat exchanger and charge cooler can struggle. The ECU pulls boost and ignition to protect the engine, which makes the car feel flat. The CSF Heat Exchanger upgrade improves charge cooler efficiency by reducing coolant temperatures feeding the manifold-mounted charge cooler, delivering consistently cooler charge temps and faster recovery between pulls.
Why choose the CSF Heat Exchanger
- Significant intake air temperature (IAT) reduction with faster heat soak recovery
- Helps improve airflow to the rest of the cooling system for lower engine water and engine oil temperatures
- 2-row, 42 mm ultra high performance core
- 6.5 mm tall multi-louvered fin with CSF’s exclusive B-Tube technology
- 100% all aluminium, TIG-welded construction with CNC machined mounting brackets
- OEM style quick connect inlet and outlet for true drop-in fitment
- Includes rock guard and transmission oil cooler mounting kit
- Mirror finish hand polish completed in approximately one hour
- Backed by a 2-year limited warranty
- Tested and proven by CSF’s global R&D partners including leading time attack teams, tuners and turbo kit manufacturers
Real world results show around 5 to 15°C lower charge temps depending on tune level and use case. The harder you drive, the more this upgrade pays off.
