K&N has released an installation video demonstrating how simple it is to install a K&N air intake system on 2009, 2010 and 2011 Dodge Ram 1500 5.7L. This informative video walks you through the removal of the factory air box and air filter assembly to installing K&N's power gaining air intake kit 77-1561KP. Most K&N air intakes can be installed in less than 90 minutes with common hand tools. K&N air intake 77-1561KP comes with a Million Mile Limited Warranty and its high flow air filter can go up to 100,000 miles before servicing is required, depending on driving conditions.
K&N testing of this air intake showed an estimated 10 horsepower gain at 4382 rpm on a 2009 Dodge Ram 1500 with a 5.7 liter engine. K&N's 77-1561KP has an aluminum tube with a polished finish and an oversized air filter which replaces the restrictive factory setup. http://www.knfilters.com/news/news.aspx?ID=3305
