Vibrant Performance Classic Filters features a 4-ply cotton gauze filter element that allows for significantly more air flow than a stock filter while also providing excellent filtration of airborne particulate. Each filter is pre-oiled and is washable and reusable. They feature a velocity funnel cap to allow smoother high velocity air flow for more accurate sensor reading and increased performance.

Filter Cap OD: 5.000"
Filter Base OD: 6.000"
Height: 6.500"

 It is recommended that the filter element is cleaned every 10,000 - 15,000 miles (16,000 to 24,000 kilometers).
