Fitting this filter into the air box on the Goldwing was a a bit tricky. Whereas the OEM filter just drops into place, this has to be gently nudged into place. It seems to be a little over-sized, but may be due to being made from a softer material. The molding tabs on the filter were not cleanly trimmed and had to be cleaned up to make it seat into groove properly. It appears to have improved mpg slightly, but will wait for longer term results to verify.
