Product Description

The K&N 77-3064KTK High-Flow Intake Kit is engineered specifically for 2006 Chevrolet Kodiak C4500/C5500 and GMC TopKick C4500/C5500 trucks equipped with the 6.6 L V8 Duramax diesel engine. This direct-fit system replaces the factory air-filter assembly and restrictive intake path with a mandrel-bent aluminum tube and oversized high-flow filter - improving airflow, throttle response, and engine sound while maintaining factory mounting points.

Installation is straightforward and can typically be completed in about an hour using common hand tools. The washable filter media allows extended service intervals, and the kit is emissions-compliance certified via CARB EO D-269-34 for 50-state use. Always verify exact vehicle engine (6.6L Duramax) and drivetrain (RWD/4WD) before purchase.

Ideal for fleet, work trucks, or performance-minded owners of the Kodiak/TopKick series who want a bolt-on improvement without modifying other engine systems. With approximately +10 HP and +18 lb-ft of torque, this kit provides measurable gains for everyday driving, towing, or heavy-duty use.
