So I know with me posting this it's going to get me a lot of backlash. But. It works for me. It's cheaper than buying the velossa tech bigger mouth. And it's doing the same thing. I went to lowes and bought 3 in diameter air conditioner piping and a vent. Along with a coupler and clamps. My whole goal was to get as close to ambient as I possibly could. I routed the piping from under the filter box to the front of the car right next to the intercooler. I cut to fit the vent which it isn't perfect right now but it works.
I jb welded in the coupler to a 3-1/4 " hole I cut into the air box. It makes a better sound now to.
Results. I'm going off the incar thermostat but it said 70 and my sct x4 intake temps were reading 70.5-71. Which is what I was looking for.

I will attach the finished pictures in the morning

Nice job. Similar to what I did with my 2013 ST, ran tube to fog light opening. My temps are almost ambient also!
I was really happy with it. I wanted to do that but I'm going to run my brake vents through them

As an HVAC engineer, this makes me cringe a little bit. How banged up did that duct get during install? Also, how well protected is it going to be from road debris? Those dryer ducts are notoriously flimsy and terrible for pressure drop. Temperature is one thing, but if you can't get the required airflow through the duct, then you're going to end up worse off than just leaving it alone.

yea i'll have to agree with Dave, with the crimps in the duct I would imagine you are not getting much air through it all compared to the snorkel. but A+ for a DIY solution, never hurts to tinker.

it actually does supply a lot of air, especially at speed, i didn't really crimp it that bad, you get a lot of light when i shinned my flash light through,

As an IT guy i can tell you the air flow is just fine, and the temps are ambient, with the k&n filter, it flows in.. i wouldn't have done it had it not been thought out, the pipe is not crimped, and had my light bar or my siren, not been on, i would've done something a little different, but it works for me..
