K&N Air Filter HA-1018 - Honda K&N Air Filter HA-1018 - Honda
DIY service done early on Honda CB. Changed very dirty oem air filter to K&N. All good and easy but pvc moulding not as good as oem so needed a minor fettle on screw hole alignment to fit. All good though.

I did the service myself. This HiFlo filter is the same one the garage fitted last time.
