Twin Air Foam Air Filter - 154200. Dual-bonded foam design removes even microscopic dirt particles, allowing more air flow than regular two-layer filters. Flat foam sealing ring maintains a secure seal to the airbox. Filters run slightly smaller than stock, making them easier to change and increasing dead air space around the filter for better performance.
