Cold Air Intake for Ford Mustang GT (2005-2009) 4.6L Engine - Black

High-Flow Cold Air Intake for 2005-2009 Ford Mustang (Modular 3V / S197)

What It Does: Replaces the restrictive factory air box and pleated paper filter with a high-velocity aluminum intake tube and low-restriction cone filter to increase oxygen density and improve throttle response.

The Stock Mustang Airflow Shortcoming

The OEM induction system on the S197 GT is designed primarily for noise suppression and cost-efficiency rather than peak performance. The factory corrugated rubber tubing creates significant internal turbulence, disrupting laminar airflow into the throttle body and reducing volumetric efficiency. Furthermore, the enclosed plastic air box is highly susceptible to heat soak from the 4.6L engine's cooling system, resulting in elevated Intake Air Temperatures (IATs). As IATs rise, the PCM retards ignition timing to prevent detonation, which significantly diminishes low-end torque and mid-range acceleration during spirited driving.

The Engineering Solution

This kit utilizes mandrel-bent T-304 polished aluminum piping, providing a smooth internal bore that maintains air velocity and reduces aerodynamic drag. The thermal properties of the lightweight aluminum, combined with the high-surface-area cone filter, ensure a more consistent supply of dense, ambient air to the manifold. By replacing the restrictive stock filter with a high-flow, washable synthetic media, the system minimizes pressure drop across the intake tract. This optimization of the air-to-fuel ratio allows the Modular 3V V8 to breathe more efficiently at higher RPMs, delivering a documented 7-10% increase in horsepower and a 6-8% gain in torque without the need for additional permanent modifications.
