aFe Power Pro Dry S Big Honkin’ Air Filter (BHAF) 21-90058

aFe Pro DRY S Media:
This aFe filter features 3 oil-free layers of progressively finer-porosity synthetic media for maximum convenience with excellent filtration efficiency. The progressive layering of media allows the filter to flow at high levels even when dirty. The Pro DRY S filter media has been tested at 99.27% filtration efficiency.

Massive Washable/Reusable Diesel Air Filter:
With an 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 and reuse it over and over again. Since this filter is oil-free, servicing no longer requires thorough drying and re-oiling.

Rounded Open Air Filter Pleats:
aFe Performance air filters use a rounded, evenly spaced pleat design that produces more usable filter surface area for increased flow and greater dust-holding capacity. Pleats are 30% taller than 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.
