Am I the first? Maybe in a Avalon. But this was more then well worth the wait. Custom made for me. I'm going to see if I can file a patent on it then shop the design around so more can be made someday.

This is just my opinion but the short ram intakes doesn't do anything but add sound. It's sucking in hot air from the engine bay and probably caused a little lost in power.. I got the information from watching this. I once did a short air intake also for my '01, didn't like it after a week. I've been running with a K&N dropped-in filter for at least 5 years now. Someone on Cardomain made a cold air intake for their black 2nd gen Avalon by routing the air filter down into the wheel well.
I don't think hot air has anything to do with combustion. Air manages the cooling for the radiators and thus engines. Short ram forces more air w/o restrictions into the combustion chamber though it is risky with debris getting sucked in also. More air will force the ecu to compensate by injecting more fuel thus getting a little more responsive engine but at the loss of fuel efficiency hence the CEL light usually coming on.

I didn't say anything about hot air having to do with combustion. The video just proves that the short ram intake decreases horsepower when it sucks in hot air unless you drive without a hood or driving with one of the headlight off. Like I said, I have a K&N drop-in filter that produces good sound but I doubt it adds anymore than .5 horsepower which isn't noticeable. You will have a 60/40 chance of filtering out the debris, depending on where you live will depend on how long the filter will last unless you get the K&N cone filter that is reusable. My uncle used to have a '93 Accord with a cone filter, he had to changed every month due to living in a very dusty environment.
You said the video proves that short ram decreases horsepower when it sucks in hot air, that's implying one of two things- it has something to do with the combustion or engine overall cooling (hencing driving with the hood off). I see flaws in the test though. First, they did not run the tests long enough to let the ECU compensate for the a/f mixture. Second, they did not measure the volume/flow of air entering the combustion chamber (they could have had a cheapo filter that was starving the engine of air). Third, did not consider the overall cooling of the engine. The hot air does not affect the combustion but may affect the overcooling of the engine leading to performance degradation. Hot engines just do not run well since the metals start to deform. But in the video, the air temp differentials were nominal so it probably didn't affect anything. Fourth, they did not test engine responsiveness which could be objective/subjective.
Power increases with air intakes are relative to overall performance and gains are exponential. As an extreme example, I doubt you will ever see stock intakes on 500-1000hp modified cars. Gains there are relatively higher and more noticeable. I've noticed a more responsive engines with certain air intakes, but that doesn't always equate to more power.

That's all fine and dandy. I monitor my IAT's quite often on my scan tool. And the only time they get out of hand, is when I'm sitting idle. Usually they're slightly above ambient temperature. I still have the piece from the stock air box that grabs air from out side and brings it to the filter. That's what allows this to happen. In the coming weeks I will be heat wrapping the whole intake anyway. Thanks for the concern.
