Previous filter had 100000 miles. Replaced dirty filter and my gas milage went back up 3mpg. My truck can breath again

Simple install, has that typical whistle between 2,500 and 4,000 rpm. Note: didn't whistle at 1st but did after I seafoamed my truck to improve performance. Definitely pulls hills better. No need for the expensive metal ones.
