Custom Intake build/Ideas
Hey everyone! I've done a fair amount of research on the topic of intakes, and have decided that I would like to fabricate my own. Here are some of the ideas I've had on the subject:
To me, it seems like the route the air travels through the stock intake system is unnecessarily long and complicated (to many bends).
https://acurazine.com/forums/attachm...1&d=1351131431
I plan on utilizing the existing piping, but routing it in a more direct manner. I would like to bring the bottom end of the intake down near the lower driver side grill (to provide maximum airflow, like a CAI) while also cutting out the intake resonator.
https://acurazine.com/forums/attachm...1&d=1351131431
My idea is to utilize the extra area of the grill to cram as much cool air into the intake tubing as possible by installing a "collector" on the end of the piping. The collector will fit up against the grill and act as a funnel, gathering all of the air being blown through this area and FORCE it to travel through the intake piping. I would like to use a rectangular collector if possible, to really take full advantage of all that free flowing air, but if for some reason I can't make it fit, I may use a larger circumference round collector.

This also leaves a lot of opportunity for things like leaves and bugs to be snatched up by the intake, so I plan on covering the end of the collector with some sort of small grate, metal mesh (gutter guard?). At least this would help prevent larger things from being taken in, while still allowing the air to pass through easily.
The red box on the diagram below represents how/where the collector will sit and connect to the rest of the intake.

Let me know what you guys think! All feedback is welcome! Would like to hear everyone else's ideas/opinions! Maybe we can refine the idea further!

I will also most likely use some type of heat wrap around the piping, just to ensure that the cold air STAYS cold. There are a lot of really great threads on custom intakes and data comparisons between SRI, CAI, and stock (AIT's).
If anyone else has any ideas for this project, let me know!

I am going to be doing something just like that. I have a 2006 5at with a type s front bumper and open fog light holes. I am planning on running a hose directly to the drivers side hole then striaght up to intake box. I have removed the resonator box as well. I would think this would provide the car with a good amount of fresh cool air.

Let me know how yours goes and be sure to post some pics! If you have any other ideas, I'm all ears!

I don't know, with something angled that low into the grill housing you are more susceptible to having water come up through the intake. Especially if you are lowered and hit a nice puddle.
With using the stock intake parts to create a CAI, enough air will flow in while keeping a somewhat downward angle so water won't come up. It looks like a nice idea though, but also you if you have fogs installed you will have to build something around them as well.

Still figuring some things out. The benefit (in terms of water damage) with this over a traditional CAI though, is that this collector will not RETAIN water like a cone filter would if it happened to get splashed. The cotton/fiber of the filter would act like a wet rag, and just hold the moisture there instead of allowing it to run off easily.
Trying to take everything into consideration!

If you're concerned about water drill a 1/4" hole on the lower part of the elbow so if you do suck water in it'll drain out before reaching the filter. I've seen them on factory M3 intakes before.

I think if you could build something in such a way to keep a nice downward angle, you could possibly prevent any water from being sucked up all the way through the custom intake. I definitely wouldn't have anything sitting totally level with the grill insert though.
You could do as one person said and maybe drill holes in certain parts of the intake. They would have to be kinda big though, because small holes would not be able to drain such an influx of water. However, if the holes are too big a lot of air would be escaping through them negating what you are trying to create in the first place.
Whatever you decide to create, just don't go driving through a river and you should be ok.

NACA ducts start at like 16 bucks. Their inlet shape is optimized for maximum airflow, unlike the dryer ducts. Something like this:

Planning on keeping the collector somewhat angled downward to prevent anything from getting SHOVELED in there lol. The holes are a good idea, but like you said, the goal of this is to provide as much air flow as possible.
On the bright side, I think almost any kind of direct intake flow is a vast improvement over the stock route of air lol

Didn't understand why that would be necessary. lol
