AirAid CAD Series Intakes - 2004 Duramax LLY

Product Name: CAD Diesel Cold Air Intakes
Manufacturer: Airaid
Fitment Notes: 2004 GM Duramax LLY

• High-performance cold air intake systems designed to provide steady, free-flowing supplies of cold air.

The CAD Intakes retain the stock filter location but give the stock intake system a big boost with the addition of a huge air inlet that provides a steady, free-flowing supply of cold air. This is done via Cold Air Dam panels, which mount in the factory air box location and utilize any factory cold air inlet ducts that are present, while adding additional cold air passages to the filter. These panels also keep the filter isolated from the hot engine compartment air by sealing to the underside of the hood via blade-style weatherstripping.

Each AIRAID Cold Air Dam Intake is designed specifically for each vehicle application and offers a simple, trouble-free installation using common hand tools. Like the rest of the AIRAID systems, the CAD Intakes include all the necessary installation hardware and easy-to-understand instructions written with the do-it-yourselfer in mind.
