Fit check: Exact filter measurements are not verified here. Compare the original element outline, sealing face, thickness, holes and cage with the replacement. Do not use package dimensions to establish fitment. Contact Ducshop for measurement and fit assistance.

Compare the original filter, airbox opening and sealing surface before installation. Fit to the original airbox for the listed application; do not force the frame or leave a sealing gap. Follow the motorcycle service procedure and check that the airbox closes correctly.

This standard foam filter must be correctly oiled with suitable foam air-filter oil before use. Follow the supplied filter instructions for cleaning, drying, oiling and seating; never install a dry foam filter.
