@Cal
actually I don't ever use it as you say - I love driving with both windows down most of the time
almost get the mg-b type feeling
my car is bog standard so I'd be surprised if it's been fiddled with - something I think fell off, but I wasn't able to find it on the street
the front of that skiny tube is connected up to a piece by the front grill, the front part is held on with 2 ties and a a flimsy steel band that you just bend by yourself
- I think something has fallen off but I cannot SEE the shape of the part anywhere, if someone has a JAP SPI mini and would like to take a picture of the RH side air duct system I'd be very grateful
worst case is I'll have to butcher a pvc bottle and tape it up but chances are it'll bounce around and fall off
