Audi S3 Intercooler Hose Kit – APR EZ-Flow (2015–2024). A direct-replacement boost hose upgrade for the MQB 2.0T platform that improves reliability and airflow.

APR’s four-ply silicone hoses with Fluorosilicone lining resist oil, fuel vapor, and heat better than rubber, helping guard against leaks. EZ-Flow stepped transitions are port-matched for a smoother charge path, while stainless Clampco T-bolt clamps secure connections under high pressure. The kit includes both intercooler hoses and works with OEM/APR intercoolers, the OEM throttle body, and all OEM turbochargers; fits 2015–2024 Audi S3 and other MQB 1.8T/2.0T models.
