APR Turbo Inlet System - Audi S3/VW Golf R EA888.4 (MQB EVO) 2022-2026

The APR Turbo Inlet System replaces the restrictive factory components between the airbox and turbocharger with one continuous path sized for maximum flow. It starts at 80mm and expands up to 88mm to suit larger airbox setups, increasing flow by over 30 percent at each measured inlet depression on the Golf R. The hose is wire reinforced so it cannot collapse under heat and load, and it is lined with fluorosilicone for oil and fuel resistance. A removable turbo inlet adapter lets the system be modified for larger turbochargers, and a billet diverter valve connector is included. It works with the factory airbox or an APR intake for a stealth OE-style upgrade.
