Arlen Ness 18-173 Red Anodized Method Clear Stage 1 Air Cleaner Filter XL 88-17

The Method™ Series air cleaner is a forged billet air cleaner that increases horsepower and torque while allowing you to view the internal workings of your intake system.

FORGED BILLET ALUMINUM BACKING PLATE:

• Constructed from forged billet aluminum
• Features the patented Big Sucker™hidden breather technology. Each hidden breather is o-ringed at the heads and exits at the mouth of the injector/ carb to provide efficient engine breathing and a virtually closed loop system. This eliminates the need for any external hoses or hardware
• Radius air inlet provides maximum performance by providing unobstructed airflow
• Aluminum breather hardware includes specially designed breather bolts for efficient engine breathing and billet breather bolt covers for a clean look
• New patent-pending hidden breather backing plate technology for M8 engines. Each breather is o-ringed at the heads, passes through the backing plate and exits inside the mouth of the throttle body through proprietary breather tubes
• Our breathing system eliminates oil issues associated with M8 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 filter element.

HAND MADE FILTER ELEMENT:

• Each filter is made from black pre-oiled cotton for the best in filtration and flow
• Washable filter, filter tune-up kits are available
• All new filter design engineered specifically for the Method series eliminates the need for a top filter plate to be able to view internal workings of intake system

FORGED BILLET ALUMINUM FILTER HOUSING & POLYCARBONATE WINDOW:

• Machined from a single piece of forged billet aluminum for clean style, superior durability, and improved ergonomics
• Features a clear polycarbonate top that is coated with proprietary film to prevents yellowing or damage associated with UV or oil exposure for long-term durability
