ARLEN NESS Big Sucker Stage 1 Air Cleaner Kit without Cover - Black 600-306

If you're serious about unlocking your bike's full potential, air intake efficiency is non-negotiable. The ARLEN NESS Big Sucker Stage 1 delivers measurable gains in horsepower and torque by optimizing airflow at every stage of the intake tract. This bolt-on kit combines precision engineering with high-flow design—no guesswork, just results.

The Stage 1 features a pre-oiled, high-performance filter paired with an aluminum backing plate engineered with zero flat surfaces. Every intake angle promotes laminar airflow directly into the throttle body, eliminating turbulence and restriction. The one-piece aluminum top filter plate includes an integrated air venturi that further directs incoming air for maximum efficiency. This is the upgrade serious riders choose when stock intake limitations are holding back performance.
