i had one when i had my 182 the rubber edge came away from the filter although the change it. i think there made by pipercross which i also had and that did the exact same thing. theres ram air? https://www.ramair-filters.co.uk/sh...replacement-panel-foam-air-filter-element-36/
I went Ramair - I figured the KTR one was probably no better and it was very cheap. Doubt it made any difference though.
