Just because you don't see a gaping hole straight through doesn't mean there is no cold air flowing to that area. The areas around the headlight receive air from behind the bumper, just because its dark there doesn't mean there's no cold air. What mace engineering do is place temp sensors in different places of the engine bay and are able to record the temperature of those locations. They are qualified mechanical and aerospace engineers who don't just drop things in random places.
Just because they find a low temperature doesn't mean that there is airflow there. Do all the other manufacturers do that too and come up with the same readings, or is it it's the only place to put it??? Hmmmm. I've got low temp in my fridge but there is no airflow there. Airflow or the cfm is what they should be recording. I didn't say it was dark, I said there is no effective opening to allow for an adequate flow of cold air for this application. If it is so good, why doesn't the factory put it there? Because it would get in the way of the lights, right??? What about the battery on the other side. That gets in the way of the other lights.
It would be cheaper you would think for the factory to run the cai behind the lights I reckon. Why don't they do that?????
Please don't try and be dazzle me with aerospace engineers. I'm not as young and gulible as you think I am. Why would they be working in the automotive industry.
I worked in the aircraft industry at Tullamarine for over 26 years and they are about the same as chalk and cheese. We had very experienced "L.A.M.E.'S." there who knew jack about cars. "L.A.M.E." stands for...Licenced Aircraft Maintenance Engineer.
Anyway. If that cai is what you like, that's fine. You have your opinion and I have mine. I am only voicing mine and what I see as an "effective" cai.
That type of cai has it's applications because on some cars an OTR either wont fit, or the air intake design wont permit it. I just can't see it being as effective as they make it out to be, is all.
