E30 Euro Valance - Brake cooling duct options

[dinanm3atl]

I want to get some brake cooling but my E30 has a Euro Valance. Because of this not seeing a lot of ducting for the valance made for the same fitment. Opening is 7.5 x 3.25 and I found some NACA ducting but they are either too small or are REALLY big...

Little help? Photo below.

U could have a custom piece made by a heating and air guy locally cheaper than u will find an oem part. easy job for a tin shop.

NACA ducts are 15 bucks per side. I just can't find one anywhere in a close size which seems crazy.

Just need a flat piece with a 3in hole. Everything else is made available to bolt on :)

always seems anything we need for an e30 is unavailable, never been made or doesn't exist.

Well in the US this size fog light opening is not made. If I had a 88-91 I could just get a replacement piece for the fog light! Not so much on Euro Valance :(
