Interesting guys. I have a K & N air filter in my stock air box so I wouldn't think I would be getting much resistance from that. You have me wondering about just running some PVC, hose, etc., to the stock inlet to get some cooler air to it. Thoughts on that?
Thanks for contributing everyone, keep it up!

I guess you
I guess you could connect a tube directly from the stock box to the front of the engine bay and to stop any air ram effect you could use a T on the end possibly negating any air ram effect that may happen.
My concern is this could cause an air ramming effect feeding directly from the front of the truck this could actually cause more problems that help.

Yeah for real.. I notice on my 97 the direction the fan is spinning off all that heat is to the right side strait towards the inlet for the intake..
And Ive seen many times where that seems to be the hottest area under the hood other than right by the manifolds..
So unless you get the one with the special heat sheilds that seperate the filter from the rest of the engine compartment I do not see anything but a little better air flow response and sound; but your still sucking in hot air..
I think this is really the key of rather buying a cheap one vs buying a more expensive one. The deciding factor would be that.. and the ability to direct air from the outside directly into the filter area.
I'm sure someone will correct me if I'm wrong.. but this is my observations.. maybee if you could direct it to the left side of the truck besides the batter in that hollow area then you would pulling in truly colder air.. but not on the right with out the right dividers to separate and keep that hot air from getting to the filter..
But when i get back from NJ trip ill be gone on for 2 weeks I'm going to resume my inlet from the grill like I was going to do before.. but I'm just going to sue the stock Airbox.. I'm a 4x4 and i dont want to worry about water and junk soaking the filter..

A CAI only produces power on top end. MPG increases will be very minimal if at all. If you're looking for cooler air then make your own out of pvc and use intake heat wrap, this will help keep under hood heat from warming up the tubing. Then get a large cone filter, really doesn't matter what brand, and angle it slightly towards the side of the radiator. Cut/remove the rubber piece next to the radiator, like 98DAKAZ did. Now get some cheap sheet metal and make your own heat shield. Make sure to heat wrap the shield also. Bam, instant cooler air. I did all that with my 2.5 and I felt a big difference in response and top end power. I put a temp recorder in the intake tube and drove around for about an hour and it was pulling 76.9-91.6 degree air.

My personal preference...not just because it's what I have but because it saves you lots of money. This is on a 4.7 V8 with a K&N filter in the box (would have a cheap filter but the K&N from my 4.0 Jeep fit)
Mine was like this...I think they come stock with rubber in the way or something though.

removed the elbow thing and also cut a hole in the side of the box opposite of the engine.

This is the one I was looking at. I assume it is the short one?
