Description
Fits: 2001-2004 Chevrolet Silverado/GMC Sierra 2500HD/3500HD 6.6L LB7 diesel only; excludes the 2004 LLY engine.
This application-specific AIRAID cad intake uses a serviceable filter and a vehicle-matched inlet arrangement. Its supplied panels or airbox manage the filter area without changing the truck into a different engine or emissions configuration.
Selected part: 201-129 — Red dry / service filter 701-469. Quantity: one selected kit or service package, not all options.
Included components
filter, MAF and rear dam panels, filter adapter, intake tube, hump hose and coupler, weatherstrip, clamps, fasteners and T20 bit
Installation and service
Reuse the factory MAF sensor, filter minder and grommet; fit the supplied sensor screws and spacers, not the original screws.
Service only with products appropriate to the selected media: oiled filters require cleaning, drying and controlled re-oiling; dry synthetic filters must not be oiled.
Emissions and application notes
Official CARB EO D-609-18 lists the selected part numbers for the stated application only. Follow its installation conditions and retain the factory emissions systems and calibration. This is not a universal road-legality claim; other applications and jurisdictions require separate verification.
