Porsche Macan S / GTS / Turbo Flat 6 Motorsports High Flow Intake System


The Flat 6 Motorsports High Flow Intake System is the most advanced engineered intake system available for the Porsche Macan. Aided by CFD analysis, F6 optimized the intake air flow, providing a maximum power increase. The composite ducts paired with the bell-horn shape and proprietary filter media creates an optimum surface to distribute air inside the factory airbox to maximize air velocity and flow. This system integrates directly to the factory airboxes enabling a simple installation and OEM fit & finish.

PROCESS:  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 air filter boxes. 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. They achieved this by opening up the duct that connects to the hood to allow more air flow into the airbox. They 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.

MATERIALS:  The composite option is a carbon-infused nylon polymer material that is produced in a very high-end 3D printing process called Selective Laser Sintering (SLS). For the filters, Flat 6 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:  All that is required is simply removing 4 screws from the OEM top, removing the OEM filter and replacing it with the Flat 6 Motorsports High Flow Filter, then reusing the gasket on the Composite Intake Ducts and bolting down the ducts to the OEM airbox. This job can be done in 15 minutes with a T-30 or T-25 torx bit. Detailed installation instructions are included with every order.

ABOUT FLAT 6: Flat 6 have designed, developed, and sold performance solutions in the aftermarket industry since 2002. In 2008, they began working with Porsche vehicles starting with the 996 911. That passion for Porsche grew both as tuners and enthusiasts of the brand. They have owned and tracked various Porsche models competing in amateur time attack competitions and local track day events.
