K&N 06 GM Trailblazer/Envoy L6-4.2L Performance Intake Kit

This K&N 57-3062 performance intake kit is made for your 2006 Chevrolet Trailblazer or GMC Envoy with the 4.2L inline-6 engine. It's designed to help your engine breathe easier by replacing the restrictive factory airbox with a more efficient system. By increasing the volume of airflow, you can expect a noticeable boost in both horsepower and torque.

The kit features a rotationally-molded high-density polyethylene (HDPE) tube, which is a well-built component that helps direct cooler air into the engine. This system includes K&N's washable and reusable High-Flow Air Filter, made with oiled cotton gauze media. The oversized, conical shape of the filter is key to its performance, and under normal highway driving, you can go up to 100,000 miles before needing to service it. A custom heat shield is also included to block hot air from the engine bay, ensuring your engine gets the coolest air possible for optimal performance. K&N backs this kit with their Million Mile Limited Warranty.

Installation is typically straightforward and can often be completed in under an hour, with no special tools required beyond basic hand tools. This intake is designed as a direct replacement for your stock air intake system.
