APR 19-26 Porsche Cayenne 4.0T EA825 Intake System

The intake filter underwent optimization on the flow bench to maximize airflow while utilizing a filter media that provided adequate filtration and extended filter life. Through several design revisions verified on the flow bench, we increased CFM by up to 12% over the stock unit! The overall shape and design of the filter resemble the factory unit due to its location, but it internally features several enhancements to enhance airflow beyond simply changing filter media. Next, the turbocharger plenum was upgraded. The factory plenum is small and features a flow-restricting split-body design. We eliminated this and replaced it with a large, organically shaped single-body design to promote airflow. Forged Carbon fiber was used not only for its aesthetic appeal but also because it allows for thin walls and complex geometry to maximize cross-sectional area. This aids in airflow and reduces pressure drop. The APR plenum is significantly larger than the factory unit in various areas and is a single-piece design that extends past the integrated PCV and EVAP bungs and runs all the way down to the new billet aluminum high-flow turbocharger inlets - less restriction, more airflow to the engine.
