K&N's 57-3000 air intake system for GM diesel and Silverado diesel heavy duty trucks

K&N Engineering has designed a performance air intake system (57-3000) that is street legal in 50 states for the 2005, 2006 and 2007 Chevrolet Silverado diesel engines and the 2005, 2006 and the 2005, 2006 and 2007 GMC Sierra diesel engines. See the complete applications list below.

K&N dynamometer tests show a 15.42 horsepower gain at 2911 RPM with the 57-3000. This air intake system has a lid that goes on top of the heat shield and includes a full air box.

The K&N air intake system filters harmful dirt and debris from entering the engines of these diesel work trucks. The heat shield isolates the K&N air filter (RC-5139) from the engine heat. This in turn keeps a cooler air charge going into the engine for an instant power gain. No other modifications are necessary.

The high flow technology invented by K&N and made in the USA provides the best balance of airflow and filtration. The RC-5139 is also washable and reusable and can go up to 100,000 miles before cleaning is necessary.

The 57-3000 K&N air intake system can be easily installed in 90 minutes or less with simple hand tools. The K&N air intake system is backed by the K&N Million Mile Limited Warranty.
