ARLEN NESS Sucker Air Cleaner - Carbon 18-740

The ARLEN NESS Sucker Air Cleaner delivers measurable airflow improvements and cleaner combustion through a patented closed-loop breather system that keeps crankcase vapors circulating efficiently. This bolt-on upgrade eliminates carburetor icing while maintaining the aggressive aesthetic that defines modern motorcycle performance. If you're running a carbureted or throttle-body engine, this is a legitimate performance gain—not cosmetics.

What sets this cleaner apart is the engineering: the one-piece aluminum backing plate integrates your carb support, while hidden breather passages exit directly at the carburetor mouth, creating a sealed system that prevents lean-running conditions. You get the high-flow filtration your engine demands without the tuning headaches that come with poorly designed breather systems.
