Description
Aluminum Backing Plate:
- Aluminum Construction
- Patent-pending hidden breather backing plate technology is a step up from our original patented system. Each breather is o-ringed at the heads, passes through the backing plate and exits inside the mouth of the throttle body through specially formed breather tubes
- Eliminates oil blow-bye issues associated with performance intakes on M8 engines
- Patent-pending oil catch is integrated into the backing plate and stops any excess breather oil from reaching the air filter. Oil catch is serviceable, simply bolt-on and off when your ready to wash/service the air filter
- Formed aluminum filter plate design with integrated mounting studs eliminates any internal mounting hardware
- Radius air inlet engineered to provide maximum airflow
- Outer filter lip covers the urethane on the base of the air filter for a clean look
Performance Air Filter:
- Made from black pre-oiled cotton
- Engineered for optimum air flow and filtration. Perimeter flow design brings in air from all sides of the filter while filtering out all harmful debris
- Washable and re-useable, filter service kits are available
Air Cleaner Cover Options:
- Choose a Arlen Ness® Stage 1 custom cover for an exposed performance look
- 18-up Softail (FLDE/FLSL/FXLR) single-bolt factory air cleaner covers
