This is Agency Power AP-RZR-650-SIL Aluminum Side Vent Covers Silver Polaris RZR 1000 | RZR XP Turbo. Manufactured by Agency Power.
The Polaris RZR XP | XP4 side intakes are pretty bland looking and could definitely use some added styling. The purpose of the intake vent and clutch vent is to get proper air flow to each component. To keep their functionality but add style is this pair of aluminum side vent covers. These side covers are precision water jetted with the AP logo designed into the pattern. The aluminum vent cover attaches securely with the provided hardware. The covers are powder coated in popular colors to match other parts. The side vent covers match the front grill kits and are a great addition to any Polaris RZR XP 1000 or Turbo vehicle.
