Corvette C4 Vortex Ram Induction System 1985-1989

Description

The Corvette C4 Vortex Ram Air intake kit replaces the restrictive stock air box assembly. This is a true ram air system that obtains cool pressurized air from the radiator cavity through your modified shroud. A specially designed scoop forces air into the sealed ram air box where it directly injects cold air into your engine. The filter contains an internal velocity stack which allows the air to enter directly without being first diverted to the sides of the filter. A performance mod you will definitely feel results with. Includes vortex box, filter and powerduct

15-20 HP increase at speed
