Yes, and since the SC430 has a nice intake scoop that takes air from front of the vehicle, the fans suck all the cold air and push into the air box.
I love your innovation but I believe they would just become a restriction once the CFMs surpass the flowrate of the fans.
Our scoop is pretty close to a ram-air scoop since it faces the front of the car outside of the engine bay. I wonder if it receives any pressure at highway speed like ram-air.
I put a set of high speed fans in the air intake. While it helps launch the car when I step on the gas, it messed up the air/fuel ratio when driving normally and thus the gas economy. I average about 16-16.5mpg with that setup and about 19mpg with original setup.
I removed it after a month. It's only good if I race/track the car.
Hello,it be greatly appreciate where can I purchase exactly same high speed fan and what can I do to connect the fan to work properly,( high speed fan wireing looks complicated) I think it is one of the great idea !! Thanks

I have all an extra OEM airbox for sale if anyone is interested in modifying it along this route.
There's a formula in this somewhere... Hmmm. Any plumbers? What does the act of restricting the flow of fluids have in relation to pressure? But my spider sense says that taking fluid volume from a large source and restricting it down to a smaller sorce increases pressure but reduces volume. My thought process went to a water pipe that has a larger diameter then gets reduced down to a smaller diameter. What happens to the pressure in the pipe after the size is reduced? Anyone?

Just thought I'd confirm what we already know. Yesterday I was driving around with my new ECU so I had all the ODB2 data displayed on my phone so I could get an idea of what was going on as I drove. I happened to notice that the OEM intake keeps temps within about 15 degrees of the ambient temp. So it was around 85 degrees outside and the intake temps were at 100. Very good for an OEM cold air intake design. Nothing to really be gained there.
Hold my beer...
Did this in anticipation of the new ECU mapping.
You are correct, the OEM design is the best I've seen so far.
The temp is about 5-10 degree higher than ambient temperature.

That looks pretty good, the only word of caution I would have is that from my research, it seems the "helmholtz resonator" in our intake tract is actually functional. There were dyno sheets I came across where an aftermarket intake pipe actually lost torque on the dyno. This was true on my Miata as well. YMMV but something to think about.

Nice job. I also made a hole like F sport and broken all slats in intake box like on this photo. Now i like my intake sound.
I'm curious, did either of you notice a big difference in sound? I don't think this will generate any power, but I'm considering it if I can get a little more growl.
It's not the same. He just want to tell us that he did break all the fins from the SC430 box to make it like the IS F sport airbox.
Smooth > more intake noise.
I think the fins are there to reduce the noise.
