Description

The APR Intercooler System dramatically lowers charge air temperature and resists heat soak far better the factory intercooler system. Through a massively increased core volume, superior intercooler core design and smooth, cast end tanks, APR’s engineers were able to create an intercooler capable of supporting power levels well beyond that of the factory unit. Expect increased horsepower and torque and dramatically prolonged performance.

Quick Facts

  • Dramatically lowers intake air temperature
    Increases HP while minimizing power-robbing heat soak! Dynoed 26 AWHP over to the factory system (STG 1 93)! Effective cooling for more than double factory horsepower levels!
  • Massive frontal surface area and core volume
    6.38" x 25.33" x 3.16" - 161.6 in² frnt. & 510.67 in³ volume - OEM
    11.7" x 22.00" x 3.50" - 257.4 in² frnt. & 900.90 in³ volume - APR

  • Highly effective core design
    Bar-and-plate core with staggered and louvered fins. Rigorous testing determined core style, fin density, and size. Low pressure drop + highly effective cooling = high performance!
  • Smooth cast end tanks
    Engineered for low turbulence/restriction and maximum flow. Organically shaped to promote airflow across entire core. Pressure tested to prevent power robbing boost leaks.
  • Easy to install
    Simple plug-and-play design with no trimming or drilling necessary!
  • Designed by engineers with lasers
    With the best equipment and smartest engineers, it just works!

Testing

APR’s engineers tested each intercooler in a multitude of tests to show the impact the APR intercooler has on intake air temperature. The following tests were conducted with a 2018 RS3 using our APR Stage 1 ECU Upgrade, 93 octane fuel and no other modifications. Ambient conditions during the stock intercooler tests were 78.5°F and 98.06 kPa with 60.47% relative humidity. Conditions were far worse later in the day during during the APR Intercooler testing with 87.2°F and 98.03 KPa with 42.18% relative humidity. This gave the APR Intercooler no added advantage over the stock system during the tests.

Intercooler Core Design

The APR Intercooler core is a large bar-and-plate design featuring densely packed staggered and louvered fins. This design offers exceptional cooling while balancing pressure loss across the core, and maintaining critical airflow to the components behind the intercooler system. The core size was appropriately matched to the platform, minimizing pressure drop while leaving adequate space for appropriately designed end tanks. To APR’s mechanical engineering experts, the design represented the ultimate in performance, far exceeding the capabilities of the factory intercooler. To the driver, the result is simple: Repeatable performance, even in the most demanding of situations!

Core Size:

APR’s Engineers also paid close attention to the balancing act between core effectiveness, pressure drop and space for end tanks through core sizing. With the core too small, pressure drop decreases dramatically, but typically results in a core incapable of effectively cooling. Likewise, with core size too great, pressure drop can increase, resulting in the turbocharger working harder. However, more importantly, with no space for appropriate end tanks, utilization of the core and overall effectiveness of the system diminishes rapidly, negating the benefit of the larger core. APR’s engineers were able to balance each of these characteristics to deliver maximum performance.
