Enhance engine longevity with the HARDDRIVE Oil Filter. Styled in black as a direct replacement matching OE 63731-99, this filter belongs to the HD Oil Filters product family and weighs 0.8 pounds. It utilizes advanced full synthetic media to capture finer particles and resist chemical breakdown, ensuring reliable performance without premature aging.
The filter incorporates an innovative M-Pleat zigzag design that boosts filtration area and dust capacity, supported by resin-reinforced media that remains strong under intense pressure and heat. Evenly spaced pleats reduce pressure drop, while a louvered baffle screen creates an oil swirl forcing maximum fluid contact across the media. Forming tapped threads provide clean installation. Verified fitment covers Harley Davidson models from 1982 to 2017, including the Road King, Electra Glide Ultra Classic, Dyna Wide Glide, and Softail Fat Boy across 468 vehicle variations. Verify fitment before ordering.
