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.
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.
Internally APR conducted a multitude of tests both on the street and on the dyno with thermocouples and pressure transducers placed at the inlet and outlet of the intercooler during the design phase. Data from these tests were used to chose the intercooler core available today. With the intercooler in it’s final production form, tests were conducted against the factory to measure the effectiveness of each system.
Testing conducted on the dyno provided a semi controlled environment for back-to-back stress testing the two systems. Utilizing a B8 A4 2.0T 6MT at APR Stage II power levels, six back-to-back twelve second dyno pulls were conducted with only 5 seconds of cool down times between runs. APR’s ECU Explorer high resolution datalogging system was used for raw sensor data collection.
The APR intercooler saw a beginning IAT of 29.25 °C that quickly dropped to 25.50 °C by the end of the first run and settled at only 34.50 °C by the end of the sixth run. The system effectively rejected heat soak and produced consistent dyno results. In stark contrast, the factory intercooler system did far worse. With a cooler beginning IAT of 27 °C, temperature rose to a staggering 42.5 °C after only the first run, already resulting in a poorer IAT than the APR intercooler after six back-to-back runs! As testing continued, it was clear the factory intercooler system was not built with performance in mind. IAT’s continued to rise, ending at 57.75 °C; an additional 23.25 °C higher than the APR system! This translated to a final gain of 17 AWHP over the factory intercooler by the sixth run while the power only varied by under 3 AWHP across all six runs with the APR Intercooler.

Do we ship abroad ?
Yes we do, to almost anywhere in the world though remember the postage is often high when shipping anything bulky. Most bulky items we export will go by UPS so you can track the package online, Delivery times vary due to stock and import checks.
However there are a few countries we do not ship to, some of these include: Thailand, Malaysia, Indonesia, Russia, Nigeria, Macedonia, Syria, Ukraine, Lebanon.
Why is postage on bulky items to some countries expensive compared to some other companies ?
For both yours and our safety we use well known couriers such as DPD Local and UPS for shipping, then we know exactly where it is in the world at any time and we know its going to arrive safely. We can now ship using standard post on some items, however using all methods you may incur import charges when you receive the goods for which we cannot be responsible for.

Yes we offer free fitting on most Milltek Catback systems, Just select the option at the checkout
No, Due to our Public Liability Insurance we do not fit any customer supplied parts.
Yes depending on how long the job will take and if you are happy to wait, We have a waiting area inside our reception
Yes, But please be aware most exhaust systems will not fit in the back of the car it is being fitted to! We will help cut the exhaust into sections to aid you taking the system back with you. We allow 7days for collection of your old exhaust, after this time we will dispose of the system.
