CTS B8/B8.5 Audi S4/S5/Q5/SQ5 3.0T Supercharged Heat Exchanger Upgrade

The CTS Turbo heat exchanger upgrade addresses the thermal limitations of the factory intercooling system on B8 and B8.5 platform Audi 3.0T supercharged engines. Designed to suit S4, S5, Q5 and SQ5 variants from 2008 through 2017, this uprated unit features increased core volume and improved coolant flow paths to maintain lower intake charge temperatures during sustained performance driving. Direct bolt-in fitment ensures straightforward installation without cutting or fabrication, making it an essential foundation for tuned and modified supercharged applications where heat management becomes critical.
