APR Front Mount Intercooler System (B9 S4/S5 3.0T)
The APR Intercooler System for the Audi B9 S4 and S5 3.0T 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.
- Dramatically lowers intake air temp (IAT)
The factory intercooler reaches dangerously high IAT levels, even on the stock ECU!
- Massive frontal surface area and core volume
3.125" x 5.75" x 28.25" - 162.4 in² frnt. & 507.62 in³ volume - OEM
2.250" x 16.2" x 22.00" - 356.4 in² frnt. & 801.90 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!
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 factory output. Achieving this goal took a multi-step approach focused around intercooler core selection, end tank design and install location.
