## Discrepancy

THE SILICONE GROMMET P/N 463-544 USED ON AIR BOX P/N 28P71A007-001 IS WEARING ON THE METAL STRUCTURE OF THE AIR BOX CAUSING EXCESSIVE PLAY. THIS ALLOWS THE ALTERNATE AIR VALVE TO MOVE INSIDE OF THE AIR BOX CAUSING DAMAGE TO THE AIR BOX AND VALVE. THIS ALSO IS ALLOWING UNCONTROLLED HEATED AND UNFILTERED AIR TO THE ENGINE.
