If you like your air cleaners with as much airflow as possible, then these Arlen Ness 10-Gauge Inverted Series air cleaners don't disappoint - they combine patented Big Sucker technology with an inverted filter top that maximizes airflow by pulling in air from the face of the air cleaner, as well as the traditional method of pulling in air from the sides (the filter has a pleated top and sides).
At the heart of the Ness design is a patent pending forged billet aluminum backing plate with hidden breather technology that is O-ringed at the heads, passes through the back plate and exits inside the throttle body through proprietary shooter tubes.
Now standard on all Ness inverted intakes (Inverted, Method, Clear Tear and Sidekick), the integrated oil catch ensures no engine breather oil ever ends up on the filter restricting the airflow. Oil catch’s bolt-on design allows its reservoir to be emptied when it's time to service the air filter.
Specially designed breather bolts and billet cover plates that result in a hidden hardware design with the most efficient breathing system available. Forged into the backing plate, the radius air inlet provides unobstructed airflow for more horsepower and torque.
Each backing plate is CNC-machined from forged aluminum and the advanced design concept eliminates oil blow-by issues, especially those associated with M-8 performance intakes.

The synthetic air filter does not need oil - the water-resistant filter media means it can simply be washed and reused and, in most cases, eliminates the need for a rain sock. Each filter features an inverted pleated top with pleated sides to maximize airflow by pulling in from every angle; the synthetic material is black with a stainless steel jacket.
Machined from a single piece of forged billet aluminum, the air filter housings feature an inverted intake face that acts as a velocity stack to increase performance by forcing air into the inverted air filter top.
On late model Big Twins "our breathing system eliminates the oil issues associated with M-8 engines by directing any excess breather oil back into the engine. To ensure no oil saturates the filter and restricts your airflow, we also integrated a new patent-pending oil catch that can be serviced when you service the handmade, fully washable/reusable pleated synthetic material filter element in black with a stainless steel jacket.
"The filter housings are machined from a single piece of forged billet aluminum for clean style, reduced weight and improved ergonomics. It features a built-in velocity stack that not only gives a unique look, but also increases performance by forcing air into the filter's inverted pleated top."
Matching wheels, rotors and covers also available; fitments include '08-'16 FLT/'16-'17 FLST/FXDLS(FBW); '91-up XL Sportster; '00-'17 Big Twin (except FBW) and '17-up M-8 models. A.R.B compliant (E.O. D-639-7).
