Itbs, trumpets and air filters

[midge]

I currently use 50mm length trumpets, i want to change to 60mm, i measured the depth off the air filter and its 80mm deep at the deepest point (middle, its a sausage filter) iirc you need 20mm clearence from trumpet to filter, however i jsut want to confirm this before i order!
