Does anyone know where I can get some induction ducting and a decent "vent" for the end of it? I want to enlarge the intake into my airbox and put the intake end somewhere in better airflow (not for a Scooby)

 

do a search for regal motorsport on ebay, they do all sorts of stuff like that

 

You could use brake ducting avalable from demon tweeks.

 

As above, the best place for custom intake/brake ducting is the red Demon Tweeks catalogue. Second best is B&Q/Homebase/Focus/Wickes where you can just use 4"/100mm ventilation hose and fittings which are pretty low cost.

 

I've seen various threads in the past on classics and new age where they feed ducting from one of the driving lamp bays into the filter box - some go the extra mile and make the inlet look part of the car - you'll need to remove the resonator box in the wing for this...
