2007-2008 GMC Sierra and Chevy Silverado (2500 & 3500) Trucks Gain 19 HP with K&N Air Intake.  The GMC Sierra 3500 is a heavy-duty pickup truck. It is almost a twin to the Chevrolet Silverado, a 1- ton workhorse that includes a stiff suspension, rugged frame and a very powerful engine.K&N’s 63-3066 air intake system for 2007-2008 GMC Sierra 2500 and 3500 along with the 2007-2008 Chevrolet Silverado 2500 and 3500 diesels.  K&N has designed a performance air intake system (63 Series) for the 2007 and 2008 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 63 Series 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 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.
