Product Information

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.

pleased with this one

I was comparing a couple of options before ordering. No surprises when I held it up next to the original component. It did what I needed without any drama.

back together again overall

It took a little time to line everything up, but nothing unusual for this kind of job. For my project, it worked out well. The hardest part was getting access to the old component.

Satisfied after installing on my car

Finally got around to installing this. The dimensions were close to what I expected from the product description. I checked the charge-air connections carefully before tightening everything down. Not much else to say; it fit and the job is done.

Clean finish so far

I had to work around some tight spaces, but that was more about the vehicle than the part. I have only had it installed a short while, but so far so good. I had a shop handle the installation.
