Upgrade the charge-air cooling performance of your 2018–2024 Audi S4, S5, or S5 Sportback with the APR Intercooler System, part number aprIC100023. This front-mounted intercooler is engineered to dramatically reduce intake air temperatures, minimize heat soak, and support consistent performance from the factory ECU through higher stages of engine tuning. Its direct bolt-on design provides a straightforward installation without trimming or drilling, making it a practical upgrade for street, performance, and track-focused applications.
The APR system uses a highly effective bar-and-plate core with staggered and louvered fins, organically shaped end tanks, and carefully selected fin density to promote smooth airflow across the entire core. Smooth cast end tanks help reduce turbulence and restriction, while the substantial frontal area and increased core volume provide greater cooling capacity than the original equipment intercooler. Low pressure drop helps preserve boost response, and pressure testing helps prevent power-robbing boost leaks.
