Performance Air Intake for Pontiac Grand Prix GXP (2006-2009) 5.3L

Maximize Inductive Airflow for the LS4 V8 in the Pontiac Grand Prix GXP

Who It’s For: This system is built specifically for the 2006-2009 Pontiac Grand Prix GXP enthusiast looking to extract the full potential of the LS4 engine family.

The Problem: The factory induction system on the LS4 V8 is a significant bottleneck. Because this engine is shoehorned into a transverse front-wheel-drive layout, the stock air box is cramped and uses restrictive plastic ribbing that creates air turbulence. This causes the engine to feel sluggish during rapid throttle transitions and hides the aggressive acoustic signature of the small-block V8.

The Solution: We engineered this short ram intake to streamline the path from the filter to the throttle body. By utilizing mandrel-bent aluminum, we eliminate the factory turbulence, allowing the LS4 to breathe more efficiently. This setup reduces pumping losses and improves the engine’s volumetric efficiency, delivering a sharper response that the factory setup simply cannot match.

Why This is the Ultimate Upgrade

• Enhanced Throttle Response: By replacing the corrugated factory hose with smooth-bore aluminum, you eliminate the "dead spot" often felt in the LS4 when accelerating from a standstill.
• Thermal Efficiency & Durability: The lightweight aluminum construction dissipates heat faster than stock plastic components, while the high-flow synthetic filter provides superior filtration without the maintenance headaches of oiled filters.
• Straightforward Bolt-On Fit: This kit is designed to utilize existing mounting points, meaning no cutting or drilling is required to give your GXP the airflow it deserves.
