If you shield the filter itself it also makes it a difficult push in or coming out. The melting area is located in the 1'oclock to 10'oclock area of the filter. At it's mildest it raised the silicone and made it shiny, at it's worst it bubbled the silicone and was almost completely sheared. If it wasn't a problem there wouldn't exist two separate attempts to remedy. I have a collection of filters and also photos of my various attempts to mitigate. In the latest try I have used header armor on the manifold and around the filter and so far I'm ok but this is a stopgap for the relocation kit to be up and readily available. That's what I'm waiting for.
