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!
This foam filter is constructed of the same 3-stage foam as ITG Megaflow filters, but shaped as a tube to slip over your air horns. There is no base plate or frame to take up space, and the foam can be deformed to fit in tight spots.
This Large size measures 80mm ID x 115mm OD x 165mm long (3.15" ID x 4.53" OD x 6.5" long). The shape is a straight tube with no taper or ridge at the base. You must add some type of retention mechanism (such as a zip tie or wire wrap). Sold individually.
Note: ITG Trumpet Sock filters are intended for use only when no other filter will fit. You may need to do some modifications to minimize unfiltered air leaking around the opening.
