Product Description

The K&N 77-3037KP Polished High-Flow Intake Kit is engineered specifically for the Hummer H2 equipped with 6.0 L and 6.2 L V8 engines from model years 2003 through 2009. This system replaces the factory airbox and intake tubing with a mandrel-bent polished aluminum tube and an oversized reusable high-flow filter element to significantly improve airflow, throttle response and engine sound.

Installation is designed as a bolt-on upgrade and can typically be completed in about one hour using simple tools. The washable filter media means long-term cost savings, and the kit maintains emissions-compliance in supported states with CARB EO D-269-38. Users should verify local legality before installation.

This upgrade is ideal for H2 owners looking for enhanced performance without extensive vehicle modification. Whether for daily driving, towing, or improved throttle feel, the 77-3037KP offers a measurable improvement in power and engine feel. Always verify exact engine size (6.0 L vs 6.2 L) and drivetrain before installation.
