CTS Turbo has developed an upgraded aluminium heat exchanger specifically for the Audi RS5 B9. The factory heat exchanger often does not provide sufficient cooling on tuned engines, so this solution offers a considerably larger volume than the original part.
The dual-pass core effectively complements the factory intercooler, with only minor modifications required for installation. The heat exchanger is designed for the 2.9T V6 engine with twin turbochargers and provides reliable cooling under higher loads.
Features
- High-performance aluminium heat exchanger
- Efficient dual-pass core
- Hand-welded and pressure-tested construction for reliable operation
- Works together with the original heat exchanger and intercooler
- The kit includes mounting brackets, hoses and fastening hardware
During installation, the plastic trim or heat exchanger bracket must be modified or trimmed.
Weight: 10.43 kg
Suitable for: Audi RS5 II (F5).
