I've been through several iterations of using those long-taper $4.99 black plastic funnels, squared up in front and trimmed to fit a 2.5 inch hose.
When I went to a Ranger airdam, I cut holes and adapted the same scoops.

Now I have a Mach 1 chin spoiler, cut to fit another set of DIY scoops: https://forums.corral.net/forums/gene...r-foxbody.html
The driving lights have since been removed so you can all STFU about them now
They all seemed to work. The old plastic scoop version was worth 100 degrees of rotor temp difference compared to the rotor that wasn't running a duct after it had been damaged and then removed. I don't have data on the new setup, and I've also since switched to Raybestos ST-47 pads. I've never experienced significant fade with that combo.
At the rotor end, I've used plain high-temp hose reshaped and pinched down to blow into the center of the hat:
And backing plates like these,
Which I later modified to direct the air into the hat:
None of that backing plate #### worked, and I've since ditched them.
Now, I've even cut the hose back so that it's a few inches away from the rotor, more like air deflectors I've seen on more and more factory applications. Between that, running Bosch rotors, and the ST-47 pads, I'm cracking rotors WAY less than before
