VW/AUDI PERFORMANCE PARTS: APR Carbon Fiber Intake System for VW / Audi 1.8 / 2.0 TSI / TFSI EA888 Gen 3 MQB (CI100033)



  • +10 HP Gain
  • +9 TQ Gain

The APR Carbon Fiber Intake System is an attractive high performance upgrade for the latest 1.8T and 2.0T engines as found in various MQB platform vehicles.

The factory intake design has the foundation for excellent performance, but much of this is sacrificed in an effort to meet other design requirements. With requirements set forth for only supporting factory power output levels, low engine sound levels and long service intervals, there is plenty of room for improvement.

The APR Carbon Fiber Intake System increases performance primarily by improving mass airflow through the system while still proving adequate filtration. Expect greater horsepower and torque through the power band with a more direct and responsive feel upon pressing the throttle. Sounds from the engine and turbocharger are enhanced and some may even experience better fuel economy depending on driving style.

Research and Development

Uncommon to most in the market today, APR spared no expenses during the research and development period. For the better part of a year, APR’s Mechanical Engineers created several prototype intake designs utilizing our in house Sterolithography 3D printer and other rapid prototyping techniques. Various filter mediums were tested in conjunction with the new intake designs through simulated models, flow bench analysis, dyno data collection and in real world applications all in an effort to derive the best possible solution.

Engineering and Design Information

To increase performance over the factory intake system, the intake system’s ability to flow a higher mass of air is critical. In order to achieve this, APR’s Mechanical Engineers focused on improving the pressure ratio between the inlet and outlet of the intake system, reducing turbulence, maximizing filter efficiency and keeping IAT as low as possible.

Improving the Pressure Ratio

In an effort to strive for an ideal pressure ratio (1:1) between the intake’s inlet and outlet, the intake features several key characteristics:

Through CFD optimization and flow-bench validation, the intake’s filter housing was shaped into a reducing spiral, or volute, which uses the inertia of the air entering the system to increase pressure on the outside of the filter. This creates an even pressure distribution across the entire face of the filter, rather than only a few key spots, and as such, maximizes utilization of the filtration element.

Compared to many other popular intake styles, the APR intake system allows for the use of a small, compact filter with better filter utilization as systems often twice its size. 

Unlike traditional open element filters, the APR intake design only pulls air from the grille area near the leading edge of the vehicle’s hood. In doing so, it draws air from an area of relatively high pressure. As the vehicle increases in speed, pressure continues to build and ultimately aids in the intake’s effectiveness.

By sealing the intake system, pressure created during the ram air effect and volute design is not simply lost within the engine bay. This is contrary to open element filters that pull air from a relatively low pressure region formed within the engine bay.

Reducing Turbulence

Flow disruptions and turbulence ultimately impede airflow to and from the intake filter, resulting in a performance loss. The APR Intake system takes a two-step approach to improving mass airflow in this region.

As air enters the intake entrance, directional vanes ensure airflow is properly directed towards the entire length of the intake filter rather than only a small portion. This results in a reduction of air turbulence and creates an even pressure distribution over the entire filter surface for maximum filter efficiency. As the filter becomes dirty with age, performance drop happens less dramatically as particles form evenly over a larger portion of the intake rather than localizing to one location or another.

When air flows through a smooth pipe, the speed at which the air flows is slower along the pipe’s smooth walls than is in the center of the pipe. Ultimately this results in a boundary layer that effectively reduces the cross-sectional area of the free flowing portion of the pipe, and creates drag. To minimize this effect as much as possible, the intake’s inner surface is kept mildly rough during the manufacturing process. As such, a thinner turbulent boundary layer forms, which ultimately prevents the boundary layer from growing larger as flow increases.
