ARLEN NESS Inverted Series Air Cleaner Kit — Black anodized – 91-04, 06-22 Sportster

This kit improves breathing and throttle response with a hidden breather system and a radius inlet for smooth airflow. 🔧

The forged backing plate incorporates Big Sucker™ hidden breathers that route from the heads to the throttle body, creating a virtually closed-loop system. 🌀

• An inverted top works as a velocity stack to help pull in more air.
• Performance filters use a high-flow element wrapped in a stainless steel jacket for 360° filtration.
• Washable, reusable, and water resistant; no external hoses or hardware required.
• Made in the USA; fits '88–'90 models though the breather system is not applicable for those years.
