Audi S3 Intercooler Pipe Kit - APR - EZ-Flow - 15-20. This direct-replacement boost hose system for the MQB 2.0T S3 maintains a strong charge path while retaining factory fit.

APR engineers use four-ply silicone with a fluorosilicone inner lining to resist heat, oil, and fuel vapors for long-term durability. The EZ-Flow stepped transitions are port-matched to reduce turbulence versus non-stepped designs, supporting consistent airflow under load. Stainless Clampco T-bolt clamps add connection strength and help prevent slippage at high boost. Each hose is pressure-tested, and the system works with OEM or APR intercoolers, the OEM throttle body, and all OEM turbochargers—offering added insurance against boost leaks on stock or tuned setups.
