Still no response from any of the dealers. Even wrote to one in Canada, a suggestion from one of the dealers in the states. So, in the meantime I bit the bullet this weekend and purchased an OEM filter just to have a clean one and it was $32+, what a rip off. Ordered some UNI Foam off eBay, as suggested by Baitis and going to try and make my own. Got some ideas..... Baitis if your out there, is there much pressure on your foam? I've come up with a way to install it as you did but without any support in the middle, will this be a problem? Made a frame out of aluminum that will just hold the outside edge of the filter material.
