HHR offers its Cold Air Intake System for the 957 (2007-2010) Cayenne S/GTS and Turbo/Turbo S. The cold air intake was designed specifically for the Porsche Cayenne to increase horsepower and torque through the entire RPM range.
We manufacture our own intakes in Denver, Colorado. The heat shields are precision CADed and waterjet-cut from 6000 series aluminum, and the tube bends are mandrel-bent 3" SS tube. Our objective was two-fold – reduce induction resistance and minimize heat transfer to the intake cavity. We elected to use K&N Filters as the brand of the air filters since the company has a race-proven reputation for providing the needed particulate filtering and increased airflow. The couplers are made from multi-layer, high-temperature silicone and are provided with stainless steel clamps. If your Cayenne is equipped with air suspension, we include a small K&N filter for the suspension air tube.
With the cold air intake system one of our objectives was to create more power without losing the factory appearance under the hood. Fortunately, the end result looks nearly identical to the clean factory setup; all of the factory trim pieces are completely reinstalled and the aftermarket intake is only barely visible. There are several more expensive brands that do not allow the reinstallation of the trim. The installation is straightforward and can be completed in approx. 60 minutes with basic tools. We provide complete step by step instructions. You can expect to see power gains of 15 to 17 HP.
The heat shields for our intake systems are shipped in raw aluminum form. These systems are in-stock, available for immediate shipment within 2 business days of cleared payment.
