BIG SUCKER SS FILTER CLEAR OIL & CLEANER

Arlen Ness claims this is the best and simplest performance air cleaner kits for your Harley-period!
The Ness "Sucker" backing plate features a built-in carburetor support and built-in breather tunnels at each head to decrease crankcase pressure. Each tunnel exits at the mount of the carburetor to create a virtually closed-loop system. Breather features o-ring banjo bolt seals and a radiused intake manifold. No oil hoses, no oil fittings, no leaking and no mess! All kits include a "Big Sucker" aluminum backing plate, Team Ness High-Flow air filter, simple instructions and all necessary hardware. These kits are a "Stealth" design as they are used with the stock outer air filter cover.
