Throttle Body Flow Booster Horsepower for Pontaic Firebird (1985-1997) 5.7L

High-Flow Throttle Body Flow Booster for 1985-1997 Pontiac Firebird

Designed specifically for F-Body platforms, this Throttle Body Flow Booster (Air Foil) effectively redirects incoming air to eliminate restrictive turbulence directly at the throttle body entrance, yielding measurable horsepower and torque gains.

The Stock Firebird Intake Airflow Limitation

The factory Tuned Port Injection (TPI) and early LT1 induction systems found in 1985-1997 Firebirds suffer from an inherent design flaw at the throttle body inlet. As air enters the twin-bore throttle body, it encounters a blunt central divider. This abrupt geometric transition shears the incoming air column, generating severe boundary layer turbulence and parasitic pressure drops right at the plenum entrance. This disruption not only chokes maximum volumetric efficiency but also causes sluggish initial throttle response and limits upper-RPM airflow capacity, resulting in a plateau of engine performance well before the redline.

The Engineering Solution

By installing this precision-engineered air foil, the blunt factory divider is transformed into an aerodynamic teardrop profile. This streamlined shape acts as a flow booster, effectively organizing the turbulent air into two smooth, high-velocity streams that feed directly into the throttle body bores. Delivering an independently verified increase of up to 30 Cubic Feet per Minute (CFM) of airflow, this simple but highly effective aerodynamic correction yields gains of up to 12 horsepower over the stock setup. The bolt-on unit requires no permanent modifications and takes approximately 5 minutes to install using standard hand tools. It utilizes your existing tuned port injection plate cover gasket, ensuring a factory-grade seal while maximizing the intake tract's true potential.
