Intake filter rattles on tranny mount
 

My cheap ebay filter recently melted right off the pipe. I went to autozone and bought another universal filter (they only had 3 inch + filters ) so i said eff it and used the rubber fitting from the previous filter to make the opening tighter to fit the pipe, however, I now have this larger filter which makes a rattling noise since it touches the transmission mount. I would love to avoid buying a smaller filter just to prevent this noise. I found on another thread this dude padded it with cloth, but I feel that is a fire hazard / would need to be replaced all the time. Any ideas on what I can safely pad the filter off the mount with? Preferably something that won't deteriorate in a month and will stay secured on there. Or is it best to just find a filter that properly fits the pipe?
