Great quality - install is a bit tough.
The product quality is excellent and well put together. Love the red scoop. Installation seemed simple enough, but the filter sent with this unit has no "filter retention grooves" to hold the filter in the heat shield. This makes installation VERY difficult, as the filter keeps falling into the hole below the heat shield. Had to fasten the hose clamp on the filter to keep it from slipping through. Made things a bit harder, but figured it out eventually.
