Question CSL Ducting on OEM Bumper Solution?

Going to be installing my CSL manifold this week and I have all four of the factory duct pieces and plan to utilize all of them with the factory bumper. Some individuals have mentioned that the intake hose (bmw 13717896774) is the only piece that can pose an issue, but I am curious if anyone has found a clean way to implement it to the factory bumper that would be appreciated.

If you could post pics of your solution, I think this would be a great reference thread for those of us that want to implement the ducting as oem as possible and don't want a csl bumper.

Here's what I found so far, but looking for something clean and oem plus.

Option 1)

https://forums.m3cutters.co.uk/showthread.php?t=140240









With option 1, I was thinking I could route part 774 to the main grille for ducting and probably just tie wrap it since I can't think of a cleaner way.

Option 2)

Here is the solution I saw without using part number 774 and I'm friends with the guy locally.

Any input would be greatly appreciated. Thanks!

Subbed, just installed my airbox last weekend. I now too need to figure out the air ducting from my stock bumper.

So I have used the oem csl secondary airfeed flexi pipe and connected it to a metal flexi pipe from a vacuum cleaner. Drilled a hole in the brake duct. There is an unused stubby dead end on the brake ducting. It was perfect to tap into and stick a pipe in to collect air.



If you look carfully you can see the oem csl tubing. The only problem is the dame thing vibrates loose off of the karbonious box. I need to think of a way to keep it there.

Something like the eventuri scoop would be a nice approach

I have zero knowledge on the subject but I'll just throw out an idea.

If you don't care about the OE fog lights, why not go with hard motorsport fog light deletes/brake ducts and route one to the airbox?

The stock elbow fits over the stock snorkel. If u can fit a ram air collector near the fog light, the stock snorkel and elbow will blow air right in front of the airbix opening

I have a brand new one for sale as I was going to go that exact route but I ended up installing aftermarket brake cooling ducts for track.
