I would dearly love to find a clamp on style air filter for my Z-400. I have seen a clamp on adapter advertised but no mention of what air filter to use with it. I don't trust the sealing set up of the stock Suzuki air filter in the conditions I sometimes ride in. I would prefer a Uni foam style filter that clamped on, that would be ideal. The Uni website doesn't show how its filter mounts. I wish to keep the airbox stock other than what it takes to mount the adapter ring if possible. Any Z-nuts out there been there and done that?? Thanks, dudes
