The APR Intercooler System is a massive front mounted upgrade that dramatically reduces intake air temperature (IAT), minimizes heat soak, and provides increased performance! The system is an easy to install, direct bolt-on design, that is recommended at every stage of performance.
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.
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.
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!
|Type||Fin Type||Fin Density||Pressure Drop||Cooling Effectiveness||Manufacturing Cost||Comments||Recommended|
|Tube and Fin||Straight Channel||Low||Low||Low||$||Poor Cooling||Not Recommended|
|Bar-and-Plate||Straight Channel||Low||Low||Low||$$||Poor Cooling||Not Recommended|
|Quality Bar-and-Plate||Staggered/Offset||High||Low||High||$$$||Excellent Cooling||Recommended!|
|Overly Dense Bar-and-Plate||Staggered/Offset||High||High||High||$$$||High pressure drop||Not Recommended|
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.
|System||Core Type||Thickness||Width||Height||Volume||Frontal Area|
|OEM||Tube and Fin||3.16"||25.33"||6.38"||510.6 in³||161.6 in²|
|APR||Bar and Plate||3.5"||22"||11.7"||900.9 in³||257.4 in²|
The APR system increases frontal surface area by 59% and has a 76% larger core!
