The APR Air-to-Water Intercooler System for the B9 RS4 / RS5 2.9T EA839 offers a substantial leap in performance that directly translates to more horsepower and torque, and consistent performance that's unmatched by the factory cooler. The factory cooler struggles to cool the charged air resulting in excessive intake air temperature due to its small size. This struggle results in ECU protecting the engine by pulling power during a single quarter mile pass, lap around a track, or even during a spirited drive. Simply bolting on the APR System relieves this issue, resulting in an instant boost in power and consistency. The APR system has no trouble remaining consistent thanks to its ability to resist power-robbing heatsoak!

Features:

  • 194% larger than the factory intercooler
  • 5,500cm³ vs the undersized 1,870cm³ factory unit
  • Dramatically lowers intake air temperature
  • Consistently more horsepower and torque
  • Flows more than stock at every measured pressure differential
  • CFD optimized cast aluminum end tanks
  • Proprietary aluminum cooling core
  • CNC machined and tig welded construction
  • Application specific coolant hoses
  • Application specific ez-flow charge air hoses
  • CNC bent and laser cut brackets
  • Does not negatively impact emissions
  • Does not require tuning
  • Instructions and support included

This part is legal under the provisions of EPA’s Tampering Policy dated November 23rd, 2020. The company has reasonable basis (test results) to verify that this product allows the vehicle to operate within legal emissions standards and is therefore legal to be sold for on-street use in all states that accept the legal provisions of the Clean Air Act and the EPA Tampering Policy. This product is NOT LEGAL FOR SALE OR USE IN THE STATE OF CALIFORNIA. Testing with the California Air Resources Board, in order to achieve 50-state compliance, is pending with CARB. Once testing is complete with California, and an E.O. number is issued, this product will be updated to 50-state legal status.

It is easy to see why the APR Air-to-Water Intercooler System outperforms the factory system. The upgraded cooler is 194% larger than stock, coming in at 5,500cm³ vs the undersized 1,870cm³ factory unit. The system features cast end tanks that were computationally flow optimized for a smooth airflow path and connect to all new silicone hoses with ez-flow stepped lips for a perfect connection without disruption. Likewise, all coolant hoses were upgraded with application specific routing for a clean install. With optimized flow through the intake air path with minimal pressure drop, post-cooler boost figures are higher, resulting increased horsepower on top of the lower intake air temperature.
