 Add these Smooth Bellows to your C5 Corvette and pick up some easy horsepower! This piece replaces the restrictive accordion-style factory bellows, straightening out air flow between the inlet duct and throttle body for an increase of up to 5 horsepower. A single-rib design allows adequate flex while posing minimal restriction. The Smooth Bellows is constructed of high-quality, fiberglass-reinforced silicone and includes a 5" worm-drive clamp and complete installation instructions.
NOTE: On 1997 and 1998 models, it is necessary to drill a 1/8-inch hole in the bellows to accomodate the factory fuel-pressure-regulator barb.
