An independent testing carried out by University of Wales
Trinity St David, Sprint Filter's P08 polyester tissue, the
"standard" tissue found in Sprint Filter replacement air
filters, provided the best airflow of any leading brand air
filter, including leading brand "race" filters. Sprint Filter P08
uses a special polyester filtering media with a wire diameter
of only 70 microns. Its unique weave pattern can filter debris
as small as 80 microns while having the highest permeability
for any other air filter brand on the market (our P08F1-85
excluded). The increased airflow of the P08 air filter will help
maximize your motorcycle power potential while offering
excellent filtration protection.

13. Current production vehicles are typically equipped with
paper filters, while performance vehicles used oil-
soaked cotton or sponge. An air filter job is to
guarantee good air flow while preventing significant
particles from ending up in the engine. These two
operations naturally oppose each other and that is
where Sprint Filters’ polyester filtering fabric takes a
leap above the rest. Polyester fabric is extremely
permeable, stable and is not affected by folding during
construction. Cotton or sponge air filters, on the other
hand, have a weaving that depends on the overlapping
of numerous layers, leading to poor flow in some areas
and ineffective filtration in others
