For the miles used nothing to complain about for the owner. Must be the Hyundai version is a bit different than some others.
This ADBV looks more concave on the base plate side, and the 4 ribs helps keep all but the outer circumference lip from contacting the base plate. Maybe Purolator changed the ADBV design to fix the hole cutting issue.
The adbv thick middle part doesn't appear to spill into the inlet holes on this one. I don't know how their sales are, but I seem to be the only one here who bought the expensive Boss to try. Lots here buy Fram Ultras. After returning four Boss, I got two that look OK on the louvers and anything else I could see.
