Throttle Body Flow Booster Horsepower for Chevrolet Impala (1994-1996) 5.7L

High-Flow Throttle Body Flow Booster for 1994-1996 Chevrolet Impala

Direct Bolt-on Air Foil: Eliminates power-robbing turbulence at the throttle body inlet to increase intake volume by 30 CFM and yield up to 12 additional horsepower.

The Stock Impala LT1 Airflow Limitation

The factory twin-port throttle body on the 1994-1996 Impala SS 5.7L LT1 suffers from inherent design flaws regarding airflow dynamics. As intake air rushes past the harsh, squared-off center divider of the stock unit, it creates substantial turbulence and boundary layer separation. This localized turbulence disrupts the velocity stack effect, creating a restriction that starves the Gen II small block of necessary oxygen at wide-open throttle. This aerodynamic tumbling effectively reduces the total cubic feet per minute entering the intake manifold, leading to a sluggish throttle response and bottlenecked mid-range torque.

The Engineering Solution

This Throttle Body Flow Booster, commonly known as an air foil, acts as a precision aerodynamic bridge for your intake system. By snapping directly over the factory throttle body divider, it transforms the blunt center partition into a streamlined, teardrop shape. This modification aggressively smooths the airflow path, eliminating the disruptive vortexes and allowing the air to transition cleanly into the intake runners. The result is a documented 30 CFM increase in intake flow. Installation requires zero cutting or drilling, reusing your tuned port injection plate cover gasket, and can be completed in just five minutes. By stabilizing the intake air columns, this component immediately sharpens throttle response and reliably frees up to 12 horsepower.
