APR 17-20 Audi RS3 2.5T Throttle Body Inlet System

This comprehensive system is much larger than stock thanks to the sweeping design of the cast inlet pipe, and oversized silicone hose. However, despite being dramatically larger than stock, the complete system is a negligible 2.4 lbs over stock! Simply put, the APR system is a complete upgrade from start to finish, flows better than stock and our competition, and is the only throttle body inlet system you'll ever need!

Vehicle Fitment: Fits Audi RS3 17-20, TT RS Quattro 18-22​

Please Note: 2019+ model year vehicles require the MS100198-A adapter unless the vehicle already has our full intake system with CI100038-G diverter valve adapter. On some European models, the MAP sensor in the manifold has the bolt hole opposite of the connector, rather than off to the side of the sensor, and as such, is not compatible with this part.
