Without the plastic tube that went into the fender well you will be sucking in hot air from the engine. Unless you live where it's very cold.

If you have read the entire message which I am assuming you did....you must have missed or forgotten that I also removed the rubber flap beside the rad allowing cold air to flow through the grill to the airbox. I can't see that one plastic elbow making that much of a difference in the temperature of the air going into the box....especially with the flap removed. Not sure of that but thanks for the info anyhow.

Now that you have taken the stock "snorkel" off, install an air cleaner intake hose like a Mighty Flow 96070 from Advance Auto Parts from the air box and between the radiator and headlight. I used the untrimmed portion of the rubber flap for a smoother look. Drop in a K&N filter and get ready to feel the response of ram-air!

Yea, like 01 said. I've made an insulated wall for the engine side and floor of that area, so now in 'walls off' the engine air, and the air comes from beside the rad. and the fender well.
Actually, the fender well, if you look closely, gets cooler ambient air from the cavity under the windshield! If you take of the elbow, and you're not moving, your now geeting MORE hot air form the engine compartment.
Leaving the elbow on, is a good set up from the factory!
I've gotten rid of the air hat, corrugated tube, and use a K&N drop in, with the 'air damn' I've described earlier-seems to work for me.
With the rubber flap in place, it creates a low pressure area behind it when you're moving, thus enabling the elbow to pull cooler air from the fender well, which is coming from below the winshield! The engineers have a good set up stock! Unless you wall off the hotter engine air, put the rubber and elbow back on.
It's all about pressure.-I'm a sailor also.
My 2 cents

Remarks from a major intake manufacturer.
Unless you plan on doing in excess of 200mph you really don't do any measurable "forcing" of air into the intake system. There is no difference in the performance of either the front facing inlet as used on the 98-99 intakes or the fender inlet of the 2000+ models. With the 98-99 version there aren't the AC lines that get in the way, but for the 2000+ models you would have to contend with getting through them to get out the front. Also, there is actually quite a bit of airflow into the inner fender coming from back at the base of the
windshield which is also a high pressure area.
Basically, aftermarket companies know the factory setup is good, but someone has to make parts for everyone that insists on tweaking. Later

now i am not trying to piss anyone off, this is just my observation..... when the truck is running, even at idle, my fan is spinning, the air coming off the fan is noce and cool, and is going right where the filter box is, therefore i feel that with any kind of open filter setup that the motor is getting cool air, and when i am driving there is airflow all around the engine from air coming through the grill and underneath the truck that is taking the hot air out, so i honestly can't see where the little bit of heat that stays under the hood is going to be any effect on any kind of filter setup, for example, some people swear by a fiter setup like those on carb. motors, which is a fairly warm place to draw air form on the truck, right on top of the manifold... anyhow, i just think that it doesn't get as hot under the hood as most people think it does, unless you are just cruising around town all day......sorry for the novel....

Nice thinking, guys! I applied my setup with the thought that if it didn't work, the stock setup could go back on. Actually, I got the idea for my 4.7's application from the factory system that was on my '92 5.2. Direct fresh air entered beside the headlight (only the "deflector" was removed at the entrance),up the tube to the air cleaner snorkel. What worked then works now. The mouth of the intake tube is even with the rubber flap now, so that the flap itself adds to the airflow. The idea is that cold air is being FORCED into the tube by vehicle motion, regardless of speed. Think about it: cold air being pushed down the intake instead of counting on the throttle body to suck the air instead. Anyway, the results were fantastic, on the "butt dyno" at least. Real numbers would be interesting, at any rate. $.02...

Here's something to think about. This year at Daytona in the NASCAR truck series they reduced the 2 inlet hoses diameter( that feed the carb) from 3" to 2" and this resulted in 70 less HP! I dont buy that you have to do 200 MPH to feel the difference in forced air induction. Last I heard, the Camaro does'nt do 200 MPH and it has the ram air and is rated at a higher HP than base Camaro.
I have a Airaid intake, I took the rubber flap off and that made a difference, then I got a Powerstack filter(open end style) and that made an even bigger difference...Just my opinion.

I had the 360 Intakez installed and the rubber flap removed last summer. It sounded great but after driving for a while the metal piping on the air intake was to hot to touch. I went back to stock w/the K&N drop in. Whatever differences in power and acceleration were not noticeable.

The Mighty Flow hose is plastic with internal aluminum ribs...cool to the touch. Aerodynamic forces even at slow speeds are a reality. For example, a bicycle rider averaging 20mph for 100 miles pushes over 2 tons of air aside. The air pressure in front of a moving vehicle traveling over 30 mph is considerable...The NASCAR trucks info is interesting since the trucks were only 6mph slower than the Winston Cup cars last month! I guess NASCAR didn't want the pickups to upstage the main event?!?

The trucks have never been restricted do to the amount of drag the beasts' have. But they are getting so fast that NASCAR found a way to slow them down, by just the size of the intake tubes! No plates, no carb work, just intake. Next time you're doing 35 MPH or more, stick that hand out the window and just see what an effect that air has.
