K&N has designed a performance air intake system (57-3066) for the 2007, 2008, 2009 and 2010 GMC Sierra and Chevrolet Silverado 2500-3500 diesel series. K&N dynamometer tests show a horsepower gain of 19.67 @ 2900 RPM. See the complete list of vehicles for this K&N air intake system below.

The diesel trucks that use this K&N air intake are working trucks. There is a specially designed lid that goes on top of the heat shield to create a full air box. The 57-3066 adds power and performance as it protects the engine from harmful dirt and debris.

The factory intake tube and factory air filter are restrictive. K&N gained the additional horsepower by removing the factory inlet tube and factory air box and replacing it with the bigger and smoother K&N air intake system.

The new air intake system pulls air through a washable K&N cone shaped air filter (RC-5177) which increases airflow and filtering capacity. The powder coated steel heat shield isolates and protects the K&N air filter from engine heat. The result is virtually unrestricted cooler outside air entering the engine for an immediate power gain.

It takes less than 90 minutes to install most K&N air intake systems with common tools. K&N air intakes also come with the famous K&N Million Mile Limited Warranty.
