K&N Performance Intake Kit for 2004-2005 GM TopKick/Kodiak 6.6L V8 Diesel

Boost horsepower and torque on your 2004-2005 GM TopKick or Kodiak 6.6L Duramax Diesel with a K&N Performance Intake Kit. Features a high-flow reusable filter and aluminum tube.

Maximize the power, efficiency, and airflow of your heavy-duty commercial truck with the K&N Performance Intake Kit designed specifically for 2004–2005 GM TopKick and Kodiak models equipped with the 6.6L V8 Duramax Diesel engine.

Factory air intake systems are often restrictive, forcing your engine to work harder to pull in clean air. The K&N 77-Series cold air intake replaces the stock factory air box and restrictive intake piping with a mandrel-bent, free-flowing aluminum tube engineered to smooth out and straighten airflow. Paired with an oversized, high-flow conical air filter and a custom heat shield, this system delivers cooler, denser air directly into the turbocharger for a guaranteed boost in horsepower and torque.

The included oiled cotton filter is fully washable and reusable, capable of going up to 100,000 miles before requiring service under normal driving conditions. Engineered for straightforward installation using standard hand tools, this intake upgrade is built to deliver heavy-duty performance and long-lasting durability for your commercial rig.
