AFE: Magnum FLOW Pro 5R Air Filter 4 F x 8-1/2 B x 8-1/2 T (inv) x 11 H in BHAF (Big Honkin' Air Filter)

Pro 5R Media:
This filter features Pro 5R oiled 5-layer progressively finer mesh cotton gauze media for maximum performance. The progressive layering of media allows the filter to flow at high levels even when dirty. The Pro 5R filter media has been tested at 98.6 percent filtration efficiency.

Massive Washable/Reuseable Filter:
With 8-1/2" Base x 8-1/2" Top (Inv) x 11" Height with a 4" flange, this filter is a direct replacement for the popular Donaldson paper filter P/N: ECB085011). Rather than throwing the filter away, you can now wash the filter and reuse it over and over again.

Rounded Open Pleats:
aFe performance air filters use a rounded, evenly spaced pleat design which produces more useable filter surface area for increased flow and greater dust holding capacity. Pleats are 30% taller that the paper alternative.

100% polyurethane construction:
To allow multiple cleaning cycles, the top and base are made of 100% pliable polyurethane that does not deteriorate with time or exposure to heat and chemicals.

aFe Power Universal Clamp-on performance filters have a limited 2-year warranty.
