Legroom-Friendly Arlen Ness 'Sidekick' Air Cleaners Feature Patented Tech
"The performance air filter is made from a black synthetic filter element wrapped in a stainless steel mesh and accepts a clear polycarbonate window to view the intake system in action."
Featuring the Ness patent-pending hidden breather system and patent-pending oil catch/reservoir, they deliver "increased horsepower, torque and mileage and are covered by a California Air Resource Board Executive Order (CARB EO D-639-8)."
The CNC-forged billet aluminum backing plate's hidden breather is O-ringed at the heads, passes through the backing plate and exits inside the mouth of the throttle body through proprietary shooter tubes. This eliminates the need for any external hoses or hardware for a virtually closed loop system that prevents the oil blow-bye issues associated with M-8 engines by directing any excess breather oil back into the engine.
The patent-pending oil catch/reservoir ensures no oil saturates the filter and restricts the airflow - the integrated oil catch collects any excess engine oil before it reaches the air filter - the bolt-on design allows the oil catch to be serviced when the filter element is serviced.
The radius air inlet allows for unobstructed airflow and specially designed breather bolts are hidden under billet covers for a clean look. The black pre-oiled performance air filter is fully washable and re-usable; rain socks/pre-filters and filter kits are separately available.
Outer air filter housing is CNC-machined from forged billet aluminum and features an angled shape for increased leg clearance and detailed CNC machine work. The clear polycarbonate window allows you to view your engine's intake system in action. The polycarbonate is hard-coated for long lasting durability and protection from engine oil and UV sunlight.
