ARLEN NESS Stage-1 Big Sucker - Natural - '08-'13 FL 18-510

A properly breathing engine is a performing engine. The ARLEN NESS Stage-1 Big Sucker delivers unrestricted airflow to your FL-series Harley while eliminating unsightly external breather hoses that compromise both aesthetics and efficiency. This bolt-on intake solution integrates hidden breather technology directly into a one-piece aluminum backing plate, giving you cleaner engine bay routing and measurable performance gains without fabrication.

The radius air inlet design removes restriction points that choke airflow, while dual O-ringed breather ports exit cleanly at the injector or carb mouth. You get a complete kit with hardware and instructions—everything needed for immediate installation on your 2008-2013 Softail, Dyna, or Touring model.
