Installation is a big problem
Had to reengineer the installation as specified was impossible with normal human hands Had to change by loosing another bolt to lift the mount below the filter so the rubber mount be placed from the bottom and held This also helped as the two button head Allen screws are impossible to insert from the bottom as specified. Converted the two bolts two studs by replacing the spacer with a nut and assembling the button head screws and the now studs first. Easy to assemble with two nuts in housing
Good so far after 1000 mile trip
Installed the filter on my 2013 F350 the day before a 1000 mile trip. Noticed a deeper exhaust sound and a little better throttle response. After 3 tanks of gas there wasn't any appreciable difference in gas mileage (18.5 highway @ 80 mph) oh well...sounds better. Instructions were easy to follow thanks to the pictures although the filter itself was a bit tricky to put in the box because the metal tabs kept catching on it. All in all, a very nice filter and easy install at a good price.
