I used in oder on the car,
Drainpipe (Windscreen)
Landrover (discovery 1 ) V8 flexy intake (Through wing)
45bend drain pipe bend
drain pipe (Along length of wing)
A Ford Fiesta intake pipe (P Reg I think) the pipe has a slight kink in it which perfectly lines up the horizontal length running across the wing to the original air intake for the standard 300tdi box.
metal 70mm coupler (I had this lying around)
70mm 90degree silicone bend (I had this lying around)
I'll admit that I modified the plastic bend out from the airbox as it gets smaller nearer the intake so I cut it short and then glued a piece of drainpipe to it then gaffer taped it back together.
Currently no pictures cause I was in a rush but have a couple of crappy ones on my phone.
I'll try to show and tell later.
