First remove the intake manifold sight shield followed by detaching the pcv line from the air cleaner outlet duct as the first step to replace the duct.

Cadillac Air Hose provides constant compressed air pressure to the engine to maintain sharp engine power and eliminate contamination. Started in 1902, Cadillac continues to take style into the future with aggressive lines, plush interiors, and fearless technology. It gives drivers the confidence to keep driving as the brand combines a quiet ride with aggressive acceleration without ever feeling artificial. All models, including a fast sedan to a massive SUV, have similar cabin designs that prefer clear-cut controls and unrestricted views. Cadillac reveals its bold nature once more with the hand-crafted Celestiq, sliding a glass roof and wall-to-wall screen into a machine that is reminiscent of tomorrow. Hanging behind the flash is a hundred years of proving, winning, and tremulous fiddling that makes the badge current with new drivers. Its logo is status marking without feeling like it is trying to be a snob or old-fashioned. The Air Hose is made of pliable and tough polymers and winds its way through an intake box to throttle body directing pressurized air and rejecting heat, vibration, and road grit to maintain a consistent fuel burn and a low toiled engine sound. The combination of rough construction and effortless handling holds the Air Hose up to the Cadillac standards of quiet assurance. The Air Hose contains flexible ribs that absorb the vibration and an oil resistant lining that combats the cracks that put other cheaper tubes out of commission. Proprietors replace it with rudimentary tools and feel cleaner is purer as soon as the engine starts.
