The mandrel-bent, free flowing polished aluminum tube was custom designed for these Sport Utility Vehicles. The tube mounts to the throttle body and over the fender well so that the K&N Air Filter (RU-4730) is positioned away from the engine's heat. The K&N Air Filter is further isolated from the engine by a black powercoated steel heat shield.

The 77-Series polished intake tube is equipped with stainless-steel hose clamps and black powdercoated steel brackets for support. The polished tube adds a custom design to the engine compartment.

Installation can be done with simple hand tools . This K&N 77-Series Air Intake comes complete with all the necessary hardware, including die-cast aluminum sensor adapters.
