Holley TPI/LT1 Throttle Body Air Foil
The Holley Throttle Body Air Foil increases horsepower by smoothing air intake and reducing turbulence. Made from space age elastomer it snaps easily into place. This fits 1985-92 TPI and 1992-98 LT1 applications.
The September, 2002 edition of GM HIGH-TECH PERFORMANCE magazine reported a 5.8 horsepower increase after installing this Holley airfoil kit on a stock 1994 Camaro Z28 LT1, called "The Grape Of Wrath"!
