ARLEN NESS Inverted Series Air Cleaner Kit — Chrome – 91-04, 06-09, 11-22 Sportster

The Inverted Series Air Cleaner Kit rethinks intake flow with a forged billet backing plate that features Big Sucker™ hidden breather technology and a radius air inlet for smooth airflow.

Forged billet air filter covers show an exposed design and a CNC-inverted top that acts as a velocity stack to help pull in more air.

• Hidden breathers are O-ringed at the heads and exit at the throttle body/carb to create a virtually closed-loop system.
• Performance filters use a black synthetic element wrapped in a stainless steel jacket for durable filtration.
• Black stainless steel jacketed inverted filters feature an inverted pleated top and 360° of pleated sides to pull in filtered air from every angle.
• CNC-machined from forged billet aluminum; no external hoses or hardware needed.
• Made in the USA. Will fit '88–'90 models; breather system is not applicable for those model years.
