It's not printed plastic. I'm pretty sure they're injection molded. They may have originally modeled it from 3D but not for mass production..
I wonder what the difference in volume of that horn compared to the stock unit. Clearly there is more opening on the leading edge of the aFe unit - the 'wings' on either side of the stock horn are solid.I like the look.
Well just to be honest with it being red that adds 10 HP right there!!! LOL.I got mine in and on....I don't know how much of a difference it will make. But I like the look.
Look at my build thread to see how I "sealed" that area.Mine is in. I was curious what the difference in volume was and filled the two horns with water and transfer to cup measures. The Ford factory horn leaks, so the 22 ounces I managed to capture might be a couple ounces low. The aFe Magnum is 40 ounces, no joke.
I swapped the metal spacers from the stock unit to the aFe. You need a Torx 30 driver.
Along with the Velossatech I can only guess what change this will bring. Perhaps pressure will take longer to build but since the aFe is sealed more perhaps the pressure will be more sustained.
Speaking of which I'm back to looking at sealing the 'plenum' focusing on the hood and shroud around the hood latch:
Looked like you added a seal across the area to the left of the latch. I dunno if I'd do the same even though I've picked up volume at the horn and the VelossaTech is presumably adding pressure.
I think whatever comes up from the latch is negligible considering its coming from that huge area that's undirected.
Yes. No intention to change, I doubt I will overwhelm it, and while it would be a convoluted path for grit to get to the airbox, I want to keep my truck's lungs as clean as possible. The factory horn leaks air, the aFe unit is a single molded piece. Ray's (RCMUSTANG) assessment of pressure loss from the latch opening seems reasonable.
