APR 19-26 Audi/Volkswagen EA888.3/3B/4/4B (MQB/MQB EVO/MQB AX) 1.8T/2.0T Open Air Intake System

The APR Open Intake System is here for the 2.0T EA888.3/3B engine found in the Volkswagen MK6 Polo GTI (Typ AW) and Audi MK2 A1 (Typ GB)! The system also fits other 1.8T / 2.0T EA888.3 / 3B / 4 / 4B engines found in MQB, MQB EVO, and MQB Ax platform vehicles making it a perfect low cost option for nearly any setup!The APR Open Intake System features a straight through filter design with minimal twists and bends for maximum flow and minimal pressure drop. Our proprietary washable and reusable cotton gauze high flow filter flows 22% more than stock at various depressions, registers less pressure drop at each depression, has 20% more surface area compared to stock, and uses a filter substrate material proven on other APR intake systems proven to provide the necessary filtration to last a lifetime.The filter's unique design allows for air to be fed from the front and sides of the filter with minimal restriction due to its shape and size. The outlet of the filter is massive, registering in at 127mm (5"), which has a cross sectional area 260% larger than the stock tube! Air velocity is accelerated through the system as it smoothly transitions to the factory back tube where the system either connects directly to the factory MAF housing, or to our back tube adapter, depending on engine. In either scenario, the transition is simple and clean for a perfect fit while promoting maximum flow.The heatshield and inlet pipe is made from a glass filled polypropylene material that acts as an excellent heat deflection barrier to minimize inlet temps compared to no shield at all. The airbox is fed with fresh air from the frontal inlet ducting, rather than the surrounding engine bay, or radiator, keeping the system constantly fed with cool incoming air to satisfy the turbochargers needs under even the most demanding situations. The system literally installs in minutes too as it simply pops into place on the factory mounting pegs! Fits 2020-2024 Audi A1/Q3 - 2019-2024 VW Polo/GTI/Tiguan Please Note: Vehicles with secondary air injection require CI100020-A.

Upgrade airflow and turbocharger response with the APR CI100054 Open Air Intake System, designed for Audi and Volkswagen vehicles equipped with 1.8T and 2.0T EA888.3, EA888.3B, EA888.4, and EA888.4B engines. This system is specifically engineered for the Volkswagen Polo GTI and Audi A1, while also fitting many MQB, MQB EVO, and MQB AX platform applications. It fits select 2019–2024 Volkswagen Tiguan models and 2020–2024 Audi A1 and Q3 models. Vehicles equipped with secondary air injection require APR CI100020-A.
The straight-through intake design minimizes twists, sharp bends, and restrictions to support high-volume airflow with reduced pressure drop. APR’s washable and reusable pleated cotton gauze filter provides 22% more airflow than the factory filter at various pressure levels and offers 20% more surface area. A large 5-inch filter outlet provides a cross-sectional area 260% greater than the stock tube, while the outlet stack smoothly accelerates air into the factory intake plumbing. The system supports both MAF and non-MAF engine configurations, depending on the application.
The open airbox and inlet pipe use glass-filled polypropylene to help deflect engine-bay heat. Frontal inlet ducting supplies the filter with cooler outside air instead of relying primarily on air from the engine bay or radiator area. This design helps maintain consistent airflow under demanding driving conditions while producing enhanced engine and turbocharger sound. APR’s fitment-focused design installs quickly by securing directly to the factory mounting points, providing a clean appearance and straightforward installation.
The APR CI100054 is TUV approved for the target platform through APR Germany and is emissions compliant. It is intended to reduce intake restriction, support improved throttle and turbocharger response, and place less strain on factory intake components compared with the original system. Verify engine configuration and vehicle compatibility before installation.
