Buschur Racing 3" Custom Air Filter



More info

Buschur Racing is proud to introduce the new filter selection for someone running a 3" intake. Our filter measures in at 10.75" tall, 6" around and has a opening of 3". Deep pleats in the double-layered cotton create a 10-15% increase in filtration surface. This increase allows a greater volume of air to move more freely into your engine cylinders while maintaining superior filtration. The specially designed cotton filter traps particles as small as 5 microns. Steel wire mesh encases the cotton filter, providing strength and dent resistance so you can be sure this filter will work under the toughest conditions.

Other filters use a simple pressure-molded injection process to bond the perimeter rubber to the interior components. That method saves manufacturing time, but in the process, a considerable amount of rubber can seep onto the filtering surface. While it may not look like much, that spill-over rubber can restrict as much as 25% of the intended air flow. The filters we have made use a four-step production process which virtually eliminates rubber seepage and maintains maximum air flow through the filter. Couple this with the specially designed funnel system at the end of the filter and you have a filter that has unrivaled flow and performance.
