About This Product
The Arlen Ness Sidekick air cleaner in black anodized finish is designed for riders who want maximum performance without sacrificing legroom. The forged billet housing is uniquely angled away from the rider's knee, providing a much more comfortable riding position. It features a durable, translucent polycarbonate side window with a special long-term coating, allowing you to see the internal workings. The black synthetic high-flow filter is wrapped in stainless mesh and is water-resistant, requiring only a simple rinse for cleaning—no oiling necessary. This kit fits 2018 to 2024 Softail, 2017 to 2025 FLT Touring (excluding select 2024-25 models), and 2017 to 2025 Trikes. It includes an integrated oil-catch system to keep the filter clean and is sold as a complete installation kit.
Manufacturer part number: 81-300.
