Product Details

The Flat 6 Motorsports has paired their High Flow Intake System with an optimized calibration for Cobb Accessport owners. As tested on a Macan Turbo, this set-up will add 16whp and 31 ft/lbs of torque over the Cobb OTS Stage 1 Map!

Package Includes:

  • Optimized Stage 1+ Map (Cobb Accessport is required)
  • 2x Flat 6 Motorsports High Flow Air Filters
  • 2x Flat 6 Motorsports High Flow Composite Ducts


  • Significant Flow Rate Enhancement
  • Adds 16 whp & 31 ft/lb of torque over the Cobb Stage 1 OTS map. 
  • Improved Turbo and Throttle Response
  • Tested below 1 micron to ANSI/ASHRAE Standard
  • Nano-Fiber Dry Media Filtration 
  • Simple Drop-In Design
  • Easy to Service
  • Made in the USA


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. 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 OEM materials for a clean and stylish look on the High Flow Ducts. 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 top, removing the OEM filter and replacing it with the Flat 6 Motorsports High Flow Filter, then reusing the gasket on the 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.
