APR Air-To-Water Intercooler System Audi RS4 (B9/8W) / RS5 (B9/F5) 2.9T

APR Air-To-Water Intercooler System - Audi RS4 (B9/8W) / RS5 (B9/F5) - 2.9T

APR built this air-to-water intercooler system to solve the heat soak problem that plagues the factory cooler on the Audi RS4 and RS5 2.9T. Where the stock unit is too small to keep charge air temperatures in check, this system keeps things cool and consistent, letting the ECU hold power instead of pulling it back to protect the engine.

This listing covers the Audi RS4 Avant (B9/8W) and Audi RS5 Coupe (B9/F5) and Audi RS5 Sportback (B9/F5), all fitted with the 2.9T EA839 engine. SKU IC100028.

Key Features

• Air-to-water intercooler design engineered to resist heat soak under repeated hard use
• Purpose built for the EA839 2.9T platform, replacing the undersized factory cooler
• Supports consistent intake air temperatures across track laps, quarter mile passes, and spirited driving
• Bolt on design intended to work with the factory charge piping layout

Vehicle compatibility, OEM part numbers, and fitment notes are provided in the tabs above. Please ensure your vehicle's year, trim level, and configuration are confirmed before ordering.
