K&N 02-05 Chevy Trailblazer L6-4.2L High Flow Performance Kit

This K&N High Flow Performance Kit includes a washable, reusable High-Flow Air Filter with oiled cotton filter media, a mandrel-bent aluminum intake tube, and a custom heat shield or air box. This system is designed to fit a range of vehicles, including models like the 2002-2005 Chevrolet Trailblazer, 2002-2005 GMC Envoy, and 2002-2004 Oldsmobile Bravada.

The oversized, conical filter allows for extended service intervals, potentially up to 100,000 miles between cleanings under normal highway driving. The aluminum intake tube is mandrel-bent to ensure smooth airflow, and the included heat shield or air box helps to block hot engine bay air from entering the intake. K&N guarantees an increase in horsepower and torque with this system, and it typically installs in under 90 minutes. This kit is protected by the K&N Million Mile Limited Warranty.
