Does anyone have any specific knowledge as to the effectiveness of the NACA style air scoop such as
the one which replaces the drivers (left) side headlight cover on Miatas?

Thanks!

Phil, I have no clue to the effect the NACA ducts have on performance. I have NACA ducts on both of my headlight doors. The driver's side is an original from BSP made out of fiberglass, and the passenger side, also from BSP, is made out of metal. Whether or not they impact performance, IMHO they look way cool, especially with TSIs.

I designed and built a NACA style duct in my headlamp door following some
data I got from a real NACA white paper. I made it as large as possible
using the edge of the hood for the back of the scoop. My turbo inlet air
filter is immediately behind the opening. I tested it using two digital
thermometers...one at the front "mouth" for ambient sensing the other inside
the filter opening, which is arranged such that the temp reading there would
be an accurate reading for what was going past the AFM.

At speeds above 30 mph the temps were within 4-5F of outside ambient. At
faster speeds the temp differential decreased a bit. At full stop, idle the
temp went off the scale which was something around 150F.

I concluded that it was, in fact, so capable of delivering ambient air to
the filter that I haven't yet finished the 6 inches of ducting between the
scoop and the filter inlet I'd planned on building.

Bear in mind that the opening is larger than the ones I've seen on the
market. It has an opening of about 5 sq. inches which is about the same as
the intake area. The one's I've seen commercially are quite a bit smaller.
To be effective your intake opening must be very close to the scoop opening
and prevented from getting hot air from elsewhere.

I can email a photo if you're interested.

I did not want to throw down the money for an intake lid. Besides i run an Air-Air intercooler and my Jackson so the effectivness of the intake does not really matter (except for my Bipes reading ACTUAL MAF air temp). I did the next best thing insted of an intake lid. I cut the both turn signals down to the end where there is an unused opening on the far corner of the light. All I did was make hold for the bulb and plug in and shoved it in there. The brightness seems to be very much increased and I can now see my turn signaling well from the side of the car. It's free and I think it looks racey. You have the ugliness of the frame behind the turn signals but I dont care. With the headlights up I can see my intake bedind it. Hope this helps, dont know if you are a racer on a budget. :)
As for cooler temps? I should have checked what temperature my Bipes said before and after the project so I can't help you too much thier. I am sure it reads lower, but as to how much and what speed, I dont know.

I would love to see this as well! Can you post is somewhere on the web
(e-mailing me a pic is fine but I'm guessing there will be a lot of

Looks nice, Chris!

Did you buy the duct? How'd you install it? Got any more pics?

I've built my own NACA ducts for the Track Dog (FM's race car). It's not
too difficult although you will have to compromise the dimensions from the
NACA ideal. A drill, a small reciprocating saw and a bunch of rivets...the
hard part is getting them to look good and not like something built for
function above all else :)
