Method™ Clear Series Air Cleaner - Blue
The Arlen Ness Method™ Clear Series Air Cleaner (Part 18-181) combines innovative design with durable materials to optimize engine airflow and maintenance visibility. Crafted from forged billet aluminum, this air cleaner features a clear polycarbonate window that allows you to monitor the internal workings of your intake system without disassembly. The polycarbonate is hard-coated to resist damage from engine oil, UV sunlight, and daily use, ensuring long-lasting performance. Its radius air inlet provides a smooth, unobstructed path for airflow, enhancing engine efficiency and power. The package includes a backing plate, forged filter housing, clear polycarbonate top, high-performance filter, gaskets, and all necessary hardware for straightforward installation. Designed for a virtually closed-loop system, each hidden breather is o-ringed at the heads, passes through the backing plate, and exits inside the throttle body mouth via proprietary shooter tubes—eliminating external hoses and hardware for a clean, streamlined appearance. The filter is constructed from black pre-oiled cotton, offering optimal airflow and filtration to protect your engine while maintaining peak performance. This air cleaner is ideal for riders seeking a combination of durability, style, and functional transparency, making it a perfect upgrade for custom Harley-Davidson and cruiser bikes. Its robust construction and innovative features ensure reliable operation, enhanced airflow, and easy maintenance for the long haul.
