ARLEN NESS Method* Clear Series Air Cleaner - Black 600-237

If you're running a high-performance engine, your air intake system directly impacts horsepower, throttle response, and overall efficiency. The ARLEN NESS Method* Clear Series Air Cleaner delivers a precision-engineered intake solution with the added advantage of visibility—watch your intake system work in real-time while maintaining a sealed, efficient design. Built from forged billet aluminum with a hard-coated polycarbonate window, this unit combines durability with functional aesthetics for serious riders and builders.

The closed-loop breather system eliminates external hoses and hardware, routing hidden breathers through o-ringed connections at the cylinder heads directly into the throttle body via proprietary shooter tubes. This integration reduces parasitic losses and maintains cleaner engine bay aesthetics while the high-performance cotton filter delivers optimal airflow and filtration for consistent performance.
