aFe POWER Magnum FLOW OER Air Filter, PRO DRY S (2012-2015 Civic Si)

Constructed with 100% polyurethane on all four sides, "oil free" OE replacement performance filter will outflow the stock filter by up to 16% for improved horsepower and torque. The Pro DRY S air filter uses three layers of progressively finer mesh cotton gauze media to provide maximum airflow for best performance results. Washable and reusable for multiple cleaning cycles, the tall, open, evenly spaced pleats provide excellent dust holding capacity for a longer service cycle between cleanings. An integrated urethane bump seal insures tight, no leak seal over the life of the filter.
