Type : Pro 5R Filter Material: Cotton Gauze Filter Color: Blue Crafted with 100% polyurethane on top and bottom, this high-flow, oiled performance filter is our most efficient media for enhanced horsepower and torque. Five layers of progressively finer mesh cotton gauze media ensure maximum airflow for optimal performance. Washable and reusable for multiple cleanings, the tall, open, evenly spaced pleats offer excellent dust-holding capacity for extended service intervals. An integrated urethane bump seal guarantees a tight, leak-free seal throughout the filter's lifespan.
