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

High-Flow Throttle Body Air Foil for 1994-1996 Chevrolet Caprice

What it Does: Directs incoming air smoothly into the intake manifold to eliminate restrictive turbulence at the throttle plates, improving overall engine volumetric efficiency.

The Stock Caprice Airflow Bottleneck

The factory GM LT1 throttle body features an abrupt, flat face between the dual bores. This blunt surface creates a stall zone for incoming air, causing parasitic turbulence and vortexes right before the butterfly valves. This disrupts laminar flow, resulting in a sluggish off-idle throttle response and effectively bottlenecking the 5.7L Gen II V8's breathing capability, especially during high-demand acceleration and peak RPM runs.

The Engineering Solution

The Throttle Body Flow Booster, commonly known as an air foil, bridges this design gap by adding an aerodynamic teardrop shape directly to the leading edge of the throttle body center divider. By smoothing out the dual-bore transition, it mitigates boundary layer separation and flow reversion. This bolt-on modification yields a verified flow increase of up to 30 CFM, delivering up to 12 additional horsepower and a notable improvement in throttle tip-in. Installation takes under 5 minutes with zero physical modifications, requiring only the reinstallation of your existing tuned port injection plate cover gasket.
