The APR Intercooler System is a OEM-location upgrade that dramatically reduces intake air temperature (IAT), minimizes heat soak, and provides increased performance! The system is a direct bolt-on upgrade that requires no trimming and is recommended at every stage of performance.QUICK FACTS:
- Dramatically lowers intake air temp (IAT)
Increases horsepower while minimizing power-robbing heat soak!
Effectiveness tested to over 500 HP!
21 horsepower gain over the factory system!
- Massive core size
Use of the OEM-location allows for a massive intercooler core.

APR pioneered the OEM-location direct-replacement intercooler system in 2006. Unfortunately, to the untrained eye, many intercooler designs appear the same. However, effectiveness of the system and overall performance are greatly determined by several key metrics. Alloy selection, end tank design, construction type, fin style, fin density and overall core dimensions must be analyzed and balanced accordingly to deliver class-leading performance. While the OEM’s goal is to create a lightweight, easy to manufacture and inexpensive to produce, cross-platform design capable of supporting factory power levels, APR’s intercooler must be capable of supporting more than double the factory output. Achieving this goal took a multi-step approach focused around intercooler core selection, end tank design and install location.TESTING:
Back-to-back stress testing on the dyno help to further prove APR’s intercooler upgrade’s effectiveness compared to the factory unit. Tests were first conducted with an APR Stage 2 MK7 GTI using the factory intercooler, then the slightly upgraded Golf R intercooler and finally APR’s Intercooler system. Each dyno pull lasted 12 seconds with 5 seconds of dwell between runs. Raw sensor data was collected using APR’s ECU Explorer high resolution datalogging system.
The tests quickly proved the long sought after OEM “upgraded” cooler (factory Golf R intercooler) showed minimal improvement over the standard GTI unit. However, the APR intercooler saw a dramatic difference that made a positive impact on performance.
The factory GTI and Golf R intercoolers saw a starting IAT of 43 °C and 42 °C which climbed to as high as 71 °C and 66 °C, respectively, by the end of only the first pull. In contrast, the APR intercooler system saw IAT’s drop to 40 °C! The APR system effectively rejected heat soak and by the end of the sixth run saw a final IAT of 49 °C where as both the GTI and Golf R intercoolers struggled to keep up, resulting in a final performance robbing IAT of 84 °C and 82 °C. This translated to a final gain of 21 WHP over the GTI intercooler and 18 WHP over the Golf R Intercooler!FITS:
