If you need a great intake system that’s easy to install, look no further.  APR brings you a product you should not be overlooked.  An all carbon, flow bench tested aftermarket masterpiece could be delivered right to your door.  The APR Carbon Fiber Intake System increases performance primarily by improving mass airflow through the system while still proving adequate filtration. You’re going to get greater power and torque throughout the power band.  Sounds from the engine and turbocharger are enhanced and some may even experience better fuel economy depending on driving style.  The APR Carbon Fiber Intake System is an attractive high performance upgrade for the latest 1.8T and 2.0T engines as found.  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.  You’re looking at nearly 20 horses of improvement.

APR Intake VS Stock:

Improving the Pressure Ratio:

Unlike traditional open element filters, the APR intake design only pulls air from 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.

High Pressure Inlet Snorkel and Sealed Design:

Reducing Turbulence:

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 event 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.

Directional Turning Vanes:

Intake Air Temperature Management:

Intake air temperature (IAT) plays a critical role in engine performance, especially on turbocharged engines where the ambient air temperature is raised twice through both compression via the turbocharger, and then again during the engine’s compression stroke.

In an effort to maintain the lowest possible starting IAT, the APR Intake system begins by drawing air from the coldest possible location, which is the front end of the vehicle before the radiator. Air travels a short path through the intake system, past the filter and on its way to the turbocharger through a sealed intake design that prevents ingestion of hot, under-hood. Finally, the intake’s carbon composite design features a thin fiberglass backing, which improves thermal insulative properties

Filtration

APR’s design requirements called for an intake filter medium that exhibited high flow capabilities, long service life and adequate filtration properties. While traditional paper filters and even some foam filters can achieve one or more of these requirements, only a pleated cotton filter was able to achieve all three. This is due in part to the intake housing’s volute design and turning vanes. With even pressure flow distribution across the entire filter element, the filter is loaded more evenly, retaining performance over time, increasing the length of the maintenance intervals, and increasing the filter's effectiveness.
