K&N has a new installation video demonstrating the simple install process of K&N air intake 57-3021-1.
This easy to install performance air intake fits 1999 through 2004 Chevy Silverado 1500 and GMC Sierra 1500 models with 4.8L and 5.3L engines. K&N air intakes
are guaranteed to increase horsepower, they come with a Million Mile Limited Warranty and
they can go up to 100,000 miles before air filter servicing is required, depending on driving conditions.
K&N's 57-3021-1 non-metallic tube dramatically reduces intake restriction as it smoothes and straightens air flow resulting in a guaranteed power gain. Dyno testing was done on a 2000 Chevy Silverado 1500
pickup with a 5.3 liter engine. It showed an estimated peak gain of 9
horsepower at 5352 rpm. K&N's 57-3021-1 is available and easy to install
on your Silverado or Sierra 1500 pickup truck, usually in less than 90 minutes. This video provides a summary of the installation process but you should always refer to the 57-3021-1 instruction sheet for full installation details.
