The aFe cold air intake system upgrade for the Porsche 911 Carrera – 991 delivers a 14% increase in air flow to the 3.4L or 3.8L flat 6 engine. This results in a power gain of approx. 15HP and an additional 13 FT Lbs of torque on tap. The intake system features a plastic housing and cover that box and hide the twin Pro 5r air filters. The cover can be left out of the installation for a further improvement in air flow, however, this will likely increase the temperature of the intake air.
The smoothly designed tube bringing the air through to the throttle body optimizes flow without compromising the fitment. The housing re-uses all of the factory mounting points making installation straight forward.
+ Performance Specifications
+ Our Opinion
Good quality upgrade for the 991 that adds power and a little sound under throttle. Power gains will likely dial back a little as the engine management system adapts to increased air flow. However, combine this with a ECU tune, plenum and exhaust and you can definitely make significant power gains and keep them.
+ Installation
Installation requires the removal of the rear bumper which is best to have two people control. With the bumper out of the way, the air intake box with it’s filters is simple to install. Full instructions are available, however, if your not comfortable tackling it yourself we recommend that you find a local independent shop can help.
