Description
The ARLEN NESS Big Sucker Stage-1 transforms your intake system into a high-efficiency breathing apparatus that eliminates restrictive external hoses while maximizing airflow to your engine. This bolt-on kit delivers measurable gains in throttle response and engine efficiency by routing breathers directly through the intake mouth, keeping your engine bay clean and functional. Whether you’re running a carbureted or fuel-injected Harley, this is the proven upgrade that separates serious builders from casual riders.
