Has anyone found a NACA duct with a 4" round outlet? I have read several post discussing it, but have not found a source. I'm hoping to find one that is set up for a 4" SCAT hose. Looking for a source to buy one if anyone has a suggestion.
Thanks,
Brad

Check with Bonehead composites. I have seen a NACA vent that I believe was from them that was close to 4". I didn't see the size listed on their website.

Yes go to Summit Racing and search brake cooling duct.
They have a large selection of 2-4" NACA scoops also very good pricing on 2-4 silicon hose and there shipping cost is not a rip[ off!
