Constructed with pure polyurethane on the top and bottom, this high flow oil-free OE replacement performance filter outflows stock filters for improved horsepower and torque. Two layers of progressively finer mesh synthetic media give maximum flow and easy maintenance. Washable and reusable for maximum time between cleanings, the tall, open, evenly spaced pleats provide improved dust catching capacity for longer intervals between cleanings. Integrated urethane bump seals ensure a tight, no-leak seal over the long life of the filter.
