    WTB: Mesh filters for MFI HB intake trumpets

    I saw these in photos of 911 2.5 ST 911 230 1687 post restoration and wondered if anyone knew where to source these clip on mesh filters? Presumably they have a flexible collar to stretch over the widest part of the trumpet and then contract again to give a good fit? I have looked on eBay and found similar ones for Weber carbs up to 70mm diameter but the Porsche Delrin trumpets are 84.75mm outside diameter...

    Any ideas @gled49?

    Thanks!

    Thanks Bob.

    I actually found them on the Mittelmotor website and they said they only have red ring ones which I think won’t look as good as the black, unfortunately. I’ll try TRE…
