For more information, visit www.P65warnings.ca.gov.The APR Intercooler System (IC100023) is the definitive cooling solution for the Audi B9/B9.5 S4 and S5. The factory intercooler is significantly undersized, leading to performance-robbing heat soak even on stock vehicles. APR’s system replaces the OEM unit with a massive front-mounted intercooler that boasts 119% more frontal surface area and a 58% increase in total core volume. This upgrade is essential for maintaining consistent power delivery and preventing the ECU from pulling timing due to high Intake Air Temperatures (IATs).
The system features a high-efficiency bar-and-plate core with staggered and louvered fins, optimized through rigorous testing to provide maximum cooling with minimal pressure drop. The smooth cast-aluminum end tanks are organically shaped to ensure uniform airflow across the entire core while remaining pressure-tested against boost leaks. Designed with laser-precision, this intercooler is a true "plug-and-play" upgrade that requires no trimming or permanent modifications to the vehicle.
Core Specification Comparison:
| Specification | Factory OEM | APR System | Increase |
|---|---|---|---|
| Frontal Surface Area | 162.4 in² | 356.4 in² | +119% |
| Total Core Volume | 507.62 in³ | 801.90 in³ | +58% |
Features:
