CSE Stage 1 kit

Arlen Ness claims this is the best and simplest performance air cleaner kits for your Harley-Davidson.

The Arlen 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 black “Big Sucker” aluminum backing plate, Arlen Ness High-Flow stainless-synthetic black filter and all necessary hardware. These kits are designed to be used with CSE air filter covers with a center hole.
