Product details
Sealed, molded plastic or aluminum cover provides factory style with less intake noise than open systems. Our specially engineered air box openings pull cold air from outside the engine compartment increasing engine efficiency and producing greater performance gain. The cross-linked polypropylene rotomolded plastic air box replaces restrictive stock air box and ensures a consistent supply of cold fresh air; built-in ram scoop forces cold, outside air to filter. Precision designed molded plastic intake tube maximizes airflow volume and speed for optimum power gains. 360 degree flow, washable and reusable, limited lifetime filters are high flow and high performance.
