K&N 04-06 Chevy Colorado / GMC Canyon L5-3.5L High Flow Performance Kit

If you're looking to get more out of your 2004-2006 Chevrolet Colorado with the 3.5L engine, this K&N High Flow Performance Kit is designed to help. This cold air intake system replaces your factory airbox and filter with a more efficient setup, aiming to improve airflow to your engine. Better airflow can mean a noticeable difference in how your truck performs, especially when you need to accelerate.

The heart of this kit is K&N's signature washable and reusable High-Flow Air Filter, made with oiled cotton gauze. This design allows for more air to enter the engine while still capturing contaminants. The intake tube itself is mandrel-bent aluminum, which helps maintain a consistent diameter for smooth airflow. A custom heat shield is included to block hot air from the engine bay, ensuring the air entering your engine is cooler and denser, which can lead to an increase in both horsepower and torque. K&N backs this system with their Million Mile Limited Warranty, and it's designed to fit right without needing major modifications, typically installing in under 90 minutes.
