Description
The CSF by PWR twin intercooler set replaces both factory intercoolers on the 2020 to 2025 Audi RS Q8 with the 4.0L twin-turbo V8. Each core uses PWR’s rolled-tube design with 37 tubes against 19 in the OEM unit, joined to CNC machined billet aluminium end tanks that are 100% TIG welded. The charge pipe is welded into the top end tank, replacing the factory bolt-on plastic part and its O-ring seal. CSF designs the set to fit exactly like the OEM units, using every factory mounting point.
