GM LT1 TPI T B AIR FOIL

The Holley EFI 120-140 is a throttle body airfoil kit designed to smooth airflow for more power. It adapts to the stock GM throttle body on Chevrolet 5.7L TPI and LT1 engines in 1985-98 Camaros and Firebirds. This kit minimizes air turbulence entering the throttle body, which can lead to increased horsepower and improved throttle response.

Installation is straightforward, requiring the airfoil to be snapped into place. Made from a space-age elastomer, the airfoil is built for long-lasting performance and unobtrusive operation. GM High-Tech Performance magazine reported a 5.8 horsepower increase with this kit on a stock 1994 Camaro Z28 LT1.
