The air intake went in easily, looks great, has a little extra air intake noise, compared to the factory unit

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.
