Porsche provided an excellent cold-air delivery solution by leveraging ducts from the front grill that feeds air up through the hood and down into the airbox. One area they left room for improvement on is the design in which air velocity can be manipulated to increase power. They split the air channels into two runners and placed a duct with a large area in the middle to drive the air flow into two chambers in the airbox. Because of this, they only put two filter surface areas to bring air in. This keeps air pressure high on the outside of the filter but slows the velocity at which air can pass through the filter and into the charge pipe leading to the turbocharger.
After studying and analyzing this design, Flat 6 Motorsports developed a solution that was cost-effective and simple to install and service. The first principle was to increase the air flow in volume and in velocity. We achieved this by opening up the duct that connects to the hood to allow more air flow into the airbox. We then used CFD analysis to optimize the design of the air filter media. Advanced simulation software showed that a bell-horn like design would both maximize filter surface area and most efficiently distribute air flow around the filter which provides 360 degrees of material compared to just 180 degrees on the OEM filter. This design creates high-pressure on the outside of the filter while minimizing pressure drop inside the filter, causing an increase in stable high velocity air that leads to the turbocharger.
We chose to use the same OEM poly-blend for the replacement ducts to achieve a factory finished look. For the filters, we leveraged a world-class supplier who’s industry leading proprietary filter utilizes a dry synthetic multi-layer material. The dry fiber technology enables maximum airflow with minimal pressure drop and efficient filtration.
Installation is simple for this system which makes any able body the right fit for this DIY job. All that is required is simply removing 4 screws from the OEM duct, removing the OEM filter and replacing it with the Flat 6 Motorsports High Flow Filter & Airbox Panel Plate. Then simply reuse the gasket on the High Flow Intake Duct and bolt down the ducts to the OEM airbox. This job can be done in 5-10 minutes with a T-25 torx bit and flat-head screwdriver. Detailed installation instructions are included with every order.
