CTS Turbo Heat Exchanger, Audi RS5 (B9) 2.9T

Audi RS5 B9 Heat Exchanger – CTS Turbo

More power, lower temperatures – the ultimate heat thief is here!

Your RS5 B9’s 2.9T V6 EA839 engine deserves better cooling, especially when tuned. The factory heat exchanger in this water-to-air intercooling system is insufficient for high-performance applications, and rising coolant temperatures mean reduced power. CTS Turbo heat exchanger is larger, more efficient, and a direct replacement for the stock unit. A thick aluminum core maximizes heat dissipation and keeps intake temperatures in check.

Installation is as simple as bolting it in place – no rocket science required.

Features – Why Upgrade?

• Increased cooling capacity – Thick aluminum core ensures maximum heat dissipation.
• Easy installation – CNC-machined mounting points and direct-fit hose connections.
• Perfect fit – Direct replacement with no modifications required.
• Built to withstand hard driving – Designed for high-performance applications.

Compatibility – Which models does it fit?

• Audi RS5 B9 (2017-2023) – 2.9T V6 EA839

Note! Not compatible with older B8/B8.5 generation Supercharged RS5/S5/S4 models.

Why upgrade?

The stock heat exchanger may be fine for daily driving, but if you increase boost pressure or push your car harder, better cooling is essential. CTS Turbo heat exchanger ensures that your engine temperatures stay under control and that performance remains consistent pull after pull.
