Performance Air Intake For Pontiac Grand Prix (2004-2008) With 3.8L V6/5.3L V8 Engines Black

Maximize Airflow and Throttle Response for Your Pontiac Grand Prix 3800 & LS4 Engines

Who It’s For: Designed specifically for 2004-2008 Pontiac Grand Prix owners running the legendary 3800 Series III V6 or the high-output LS4 Small Block V8.

The Problem: The factory intake system on the 3800 Series III and LS4 is a major bottleneck. GM designed these stock air boxes with heavy baffles and corrugated plastic tubing to prioritize silence over performance. This creates significant air turbulence and heat soak, especially on the LS4 V8 where engine bay temperatures can spike, causing the ECU to pull timing and kill your low-end torque.

The Solution: We engineered this intake to eliminate those factory restrictions. By replacing the baffled plastic with mandrel-bent T304 aluminum and a high-velocity cone filter, we provide a direct, smooth path for air to reach the throttle body. This setup reduces pumping losses and allows your engine to breathe properly, delivering the aggressive induction sound and immediate throttle response these chassis deserve.

Why This is the Ultimate Upgrade

• Enhanced Power Delivery: By smoothing out the intake tract, you’ll see gains of up to 10% in horsepower and torque, particularly noticeable in the mid-range of the powerband.
• T304 Aluminum Construction: Unlike cheap plastic intakes that can crack or warp under high heat, our lightweight aluminum piping dissipates heat faster and provides a permanent performance solution.
• True Bolt-On Installation: This kit is a direct replacement for the factory air box. Most enthusiasts can have this installed in under 60 minutes using standard hand tools—no drilling or custom fabrication required.
