Arlen Ness Big Sucker Air Filter Kits for Twin Cam

PATENTED HIDDEN BREATHER BACKING PLATE:

• One-piece aluminum backing plate features our patented hidden breather technology. Each hidden breather is o-ringed at the heads and exits at the mouth of the injector/carb to provide efficient engine breathing, eliminating the need for any external hoses or hardware
• Radius air inlet provides maximum performance by providing unobstructed airflow
• Backing plates are available in Standard, Black Powder Coat, or Chrome finish

HAND MADE FILTER ELEMENT:

• Each filter is handmade in the U.S.A. one at a time using the finest materials available
• Filters are available in red or synthetic jacketed filter elements
• Standard red filters are pre-oiled, washable and feature 4-layers of surgical grade cotton for optimum filtration and maximum airflow
• Synthetic steel jacketed filters feature a synthetic material that is water resistant and never needs to be oiled. Just wash and re-use
• Unlike most other filters, our process of hand pouring each filter ensures a strong clean bond between filter element and body with no restrictive urethane residue on the filter element
