APR Throttle Body Inlet System for the Audi RS3 2.5T EA855 EVO (2017–2020) replaces the factory charge path from the intercooler outlet to the throttle body. It boosts airflow and reduces common leaks for dependable performance.
A cast aluminum inlet pairs with an oversized, multi-ply wire-reinforced fluorosilicone hose and high-strength T-bolt clamps. The billet throttle body–to–manifold adapter adds a boost/vac port, and the kit includes new gaskets and one-time-use bolts. The path grows to about 72 mm (vs 64 mm), adds only ~2.4 lb over stock, and flows roughly 34% more than stock.
Features
- Complete system: intercooler outlet to throttle body
- Single cast inlet removes two potential boost leak points
