K&N Performance Intake Kit for 2002-2005 Chevrolet Trailblazer, GMC Envoy, & Oldsmobile Bravada (L6-4.2L) 57-3036

Fits 2002-2005 Chevrolet Trailblazer, GMC Envoy, and Oldsmobile Bravada (L6-4.2L).

The K&N 57-3036 Performance Intake Kit is engineered to eliminate airflow restriction in the factory intake system. By replacing the restrictive OEM air box and intake tubing with a rotationally-molded high-density polyethylene (HDPE) tube, this system increases the volume of air delivered to your engine for a measurable gain in horsepower and torque. The HDPE construction provides a smooth path for airflow while maintaining durability under hood temperatures.

This kit includes an oversized, conical High-Flow Air Filter featuring oiled cotton media, designed to provide superior filtration and air capacity. Under normal highway driving conditions, the filter can go up to 100,000 miles before servicing is required. A vehicle-specific heat shield is also provided to help isolate the intake air from engine bay heat, ensuring a cooler, denser air charge.
