Air intake - some info, please!

All I could find around to the subject of the hot/cold air intake was about fast cars. I really don't get everything right. Could somebody, please, clear to me a couple of things?

<ul type="square"> [*]do I need cold or hot air [*]does it affect the MPG (if the air is cold or hot)[*]could it do any damage to the engine (having the air hot/cold)[*]can the intake start (filter=end) be under hood, right under the windshield, or is it too restricted &amp; too hot there?[*]Is the tube (hard rubber) of inner dia. approx. 2,5-3" too small?[/list]
It's 2.5L engine, 1993.

Thanx!

Re: Air intake - some info, please!

1. Cool air is more dense.
2. For the same volume of space there's more air in that volume when cooler.
3. It's natures "compression."
4. Cooler air in the intake gives more O2 for combustion per volume that warmer air.
5. With cooler air there may be a slight increase in MPG.
6. With Forced Cool Air Intake systems an increase of 10% - 15% are reported.
7. I would move a fresh air intake foward to the front of the engine compartment where the air would be cooler.
8. I would not use any hose that would restrict the size of the TBI or carb throat.
9. I'm not aware of any damage to an engine from such systems.

The only reason why I moved (routed) it there is because I was affraid of water going in. The way it is now, water can't get in, at least not until I get in up to the windshield.
Not that I go through water that deep, it's just that I like water, and I hit it regulary, as soon as I see it (on &amp; off the road). I got scared when I saw where the original intake was on my YJ, 'cos I just ran through a "lake" on the street, which was some 4-5" deep. I went in with some 30-40 MPH, enjoyed it a lot while water was splashing all around. And after I stopped to check if everything was all right, I noticed where thati intake was.
So I rerouted it, thinking there's no way water could get inthere. Plus, it's higher, so maybe I could hit some seriously deep water w/o having to worry about air intake.
Where should I hide it in the front, in order to stop watersplashes getting in? Behind the headlight? The grille (but the water passes there!)? Where? [img]images/graemlins/confused.gif[/img]

I have mine behind the head light and made a splash guard and bought a filter cover for it which helps a little, plus that is the area to get the best "cold air" even though its not really cold air. If you really want COLD air your going to need a snorkel.

Re: Air intake - some info, please!

I thought this was a "unique" answer to installing a snorkle on a YJ...

I thought those were to boost the air supply to the fresh air vent inside the cab?
