Performance Engineering

At the core of this intake system is a precision mandrel-bent aluminum intake tube, designed to eliminate airflow turbulence and restrictions found in the factory intake system. This smooth, uninterrupted airflow path allows the engine to breathe more efficiently, resulting in stronger throttle response and increased power output.

The oversized, high-flow air filter provides increased surface area, allowing more air to enter the engine while maintaining excellent filtration. When you step on the throttle, you’ll immediately hear the difference—a bold, throaty intake tone that brings the GXP’s V8 personality to life.

Easy Installation

Installation is quick and straightforward, requiring only basic hand tools. Simply remove the factory air box and replace it with the included intake components. Most installations can be completed in well under one hour, making this an ideal weekend or DIY upgrade.

Add easy horsepower, aggressive sound, and improved throttle response to your Pontiac Grand Prix GXP—install this performance short ram air intake and feel the difference.
