Enjoy your stay o/.
Yes had both and the pipercross one did not fit correctly so now have a K&NWould you recommend the K&N one over a Pipercross filter?
Good thing you spotted that. Thanks for the heads upWell despite me giving them the thumbs up earlier, while messing around with my Z3 earlier I discovered my Pipercross panel filter is slightly too large for the box, so when the box is clipped together it isn't actually quite shut properly. I hadn't noticed this when I fitted it and I don't think it is an issue, but it kind of smacks of either poor quality control, or them sending the wrong item without me noticing.
