Callaway Honker Air Induction System for C5 and Z06 Corvette features 26% more airflow, 18 bhp more than the factory system. Unique design eliminates the restrictive over-the-radiator "gooseneck" and relocates mass air flow sensor. Rigid base ingests cooler, denser inlet air from outside of engine compartment. Callaway proprietary low-restriction filter element is washable and reusable for extended, reliable service. Works with all OEM engine management sensors. System includes premium quality hardware and complete installation instructions. Fits 1997-2000 and 2001-2004 Corvettes.
