CSF Intercooler Set for Audi C8 RS6 and RS7 – High Performance Intercooler Upgrade

Upgrade your Audi RS6 C8 or Audi RS7 C8 with the CSF Intercooler Set, developed with PWR’s Formula 1 grade cooling technology. This is the ultimate Audi RS6 intercooler upgrade for fast road, track and tuned cars seeking lower intake air temperatures, consistent performance and reliability. If you are running a Stage 1 or Stage 2 tune on your RS6 or RS7, the stock intercoolers will heat soak and hold you back. CSF’s advanced rolled tube core and billet end tanks deliver real-world gains with a true plug-and-play fit.

Why upgrade your Audi C8 RS6 and RS7 intercoolers

  • Factory plastic end tanks can leak under elevated boost, wasting power and risking engine health.
  • OEM cores are designed for stock power and degrade over time, causing heat soak and higher IATs.
  • CSF x PWR cores keep charge temps consistently lower for stronger, repeatable performance.

Proven gains on tuned cars

  • VF Engineering saw approx +20 whp and +18 wtq on a Stage 1 tune.
  • VF Engineering saw approx +10 whp and +20 tq on a Stage 2 tune.

Key features – CSF x PWR F1-grade technology

  • Formula 1 performance grade core by PWR – 2-row core featuring rolled tubes with inner fins.
  • 45 tubes vs OEM 22 for massively increased heat rejection.
  • 3 mm rolled tube vs OEM 7 mm for improved efficiency and airflow.
  • 4.85 mm fin height vs OEM 7 mm for optimised cooling and pressure drop.
  • CNC machined billet end tanks for strength and durability at high boost.
  • 100% TIG-welded construction – no crimped plastic end tanks.
  • OEM style CNC machined inlet and outlet connections for precise fit with factory components.
  • True plug-and-play, drop-in fit – no cutting, no modification.
  • Highly engineered, lightweight design.
  • Made in the USA at PWR North America.
