Product Description

The K&N 77-3076KTK High-Flow Intake Kit is engineered specifically for 2011-2013 Chevrolet Silverado and GMC Sierra 2500 HD/3500 HD trucks equipped with the 6.0 L V8 engine. This system replaces the factory air-filter housing and intake tubing with a mandrel-bent aluminum tube and an oversized reusable high-flow filter to improve airflow, throttle response and engine sound.

Installation is designed to be straightforward - typically completed in about an hour with standard hand tools. The washable filter element and reusable design offer long-term cost savings in maintenance, while the textured-black aluminum tube adds durability and under-hood style. This kit is built for heavy-duty full-size truck applications and supports better breathing under load.

Ideal for performance-minded owners of the Silverado and Sierra HD series who want a true bolt-on upgrade without needing major modifications. With an estimated ~10 HP and ~10 lb-ft torque gain, the 77-3076KTK provides tangible performance improvements, especially in towing or heavy-duty use. Always verify your exact engine size, drivetrain (RWD/4WD) and bed/cab configuration before purchasing.
