Fit check and measurement: Exact filter-element measurements are not independently verified here. Compare the original element outline, sealing flange, thickness, mounting holes and cage arrangement before installation. Package dimensions describe shipping, not fitment. Do not force the frame or leave a sealing gap. Follow the motorcycle service procedure and confirm that the airbox closes correctly.
Follow the RFX cleaning and oiling instructions and use products suitable for foam air filters. Do not install a dry, torn, incorrectly seated or damaged element.
For Ducshop fitment and measurement assistance, call 770-424-8804 or email parts@ducshop.com with your model, model year and part number FXAF 50004 55NO.
