CSF's by-PWR intercooler system for the C8 Audi RS6 and RS7 swaps the OEM crimped cast-aluminum end tanks for 100% TIG-welded CNC machined billet aluminum tanks and an F1-grade two-row PWR core (rolled tubes with inner fins) that cuts heat soak and lowers intake air temperatures more efficiently than bar-and-plate or tube-and-fin designs. It is a true plug-and-play drop-in using OEM-style inlet/outlet connections, replacing OEM 4K0 145 805 P (left) and 4K0 145 806 B (right). Gains run +20 WHP / +18 WTQ on a stock tune and +10 WHP / +20 WTQ with a performance tune. Finished in Thermal Black heat-dispersion coating and made in the USA at PWR North America.
