More Power with an Intake Kit
Although exact pricing will vary and each installation kit is slightly different, expect to pay around $350 for a half-ton K&N Intake Kit, with the average install time (assuming you have all the needed tools) ranging from 15 to 45 minutes. Below are the K&N recorded results from their own horsepower before-and-after tests.
Ford F-150 5.4L V-8 -- +16 hp

Looking at the dyno chart, it does seem possible that the +11.21HP figure could be true.
