Filters - Crankcase Vent Breather & Universal Clamp-on

CRANKCASE VENT BREATHER &
UNIVERSAL CLAMP-ON
aFe builds a wide range of universal clamp-on filters, designed to provide performance and protection. Most sizes come in your choice of three progressive medias designed to meet your specific needs.

Extra-deep pleats and special pleat geometry maximize airflow, and inverted filter tops are standard on many Pro 5R sizes. Integral velocity stacks accelerate flow with minimal aerodynamic loss.

Velocity stack filters flow more than standard filters but require a longer flange and wider filter base.

Modified velocity stack filters are used where space is a concern or where there is already a velocity stack at the filter tube transition.
