Review on Enhance Engine Performance with 🚀 K&N 63-2575 AirCharger Air Intake System by Peris Auditore

I might be concerned, but if there's a 1" gap between the new housing and the old inlet, I get nervous. I mean the box where the old filter was and where the new housing goes. There's another filter between that space and the air intake, but I see some things spilling out in that area and I don't want that anywhere next to my filter. As for the sound, there was a big difference. A big difference. At first I thought it was pretty cool that my Expedition sounded like I was hearing some of the other American (standard) trucks. Then I realized I'm probably the only one who can hear it (it wasn't an exhaust mod) and that's a good thing. But then I really didn't like him. It's not a raspy sound, but more of a midrange sound. He started screaming pretty quickly. MPG change but I didn't give it more than one tank to really notice. To be honest the MPG sh had to skyrocket because I was trying to avoid any hard acceleration just to avoid the noise that made it.
