ITG Trumpet Sock Filters for Air Horns

If you need a high-efficiency air filter for velocity stacks but no other filtering options seem to work, the ITG trumpet socks may just save the day!

These foam filters are constructed of the same 3-stage foam as ITG Megaflow filters, but shaped as a tube to slip over your air horn(s). There is no base plate or frame to take up space, and the foam can be deformed to fit in tight spots.
