Wrapped my intake tubes with heat reflective tape.

Keep marshallows close, then.
In 10 seconds that aluminum hood will be so hot you can't open it.
Really, this is important. Tends to reveal after a mechanic has moved stuff around inside an old engine compartment. That's why I mention it. Stay safe!

Well, if I see a glow on the horizon I'll know you are looking for another car.
Search "fire" and get religion on the subject.
If you want to drive out here, I'll help you replace.

I'm reading up on it right now. I figure it would also be a good time to replace my injectors, too.

yes, I suppose you could wrap the intake tubes and insulate them from getting any heat over several hours if you were creative, BUT, for what gain. Again, it all boils down to the air flow, mass and volume being so great and the surface area being so little, that NO measurable effect will be felt at full throttle and less effects under part throttle, due to it really doesnt matter. In fact, there might be a fair debate that hoter air might create better fuel mileage.
I cant believe you guys are still talking about this. Its such a silly idea with absolutely no imaginable gains. mark kibort

I'm done with this thread, but I stand by my findings, it did help for street driving!

Its tough to argue with me, because I am the voice of REASON!
Look, if you think there is gains, show them too me and state why or how. So far NO ONE has listed anything but conjector and guesses/feelings.
why do you think radiators , heat exchangers, and intercoolers have grids to run the fluid, air through? so, heat can be transfered. in the air tubes, there is NOTHING really for the air to grab on to. not enough heat and surface area to make a difference. taking meaningless temps at the air filter at cruise is pretty sillly, unless you can prove that it increases gas mileage or something. under WOT, you wont see any gains. If you do see 5 degree temp change, that would be HUGE adn worth .1hp.

Normalized? what does that mean? I think you are imagining any benefits. Kind of like my car drives SO well right after I wash it!
you are not going to get the humidity out of the air, you are only slightly changing tempurature of the air box during cruise. does it make your car run better? well if it does, becase the sensors are not adjusting or are adjusting because you are so hot, then that is interesting. However, I still cant imagine what you are feeling.
Ive run my car without the air top for months and never noticed anything different when I finally installled the cover and tubes.(direct hot air from the engine area)
Hey, as they say, "knock yourself out" if you want to do it. have fun!

Mark, you keep talking about gains, but gains is not what this thread is about. I'm just trying to keep things normalized, and this wrapping has helped very much. I'm not sure what the weather is like where you are, but here in Va Beach it's freaking miserable because of the high humidity. This high heat and humidity makes my car run weakly, and this wrapping has helped. I'm not going to propose exactly why it's helped, I just know it has.

Mark, I don't understand how you could possibly make that assertion. Of course washing the car makes it goes faster.
Just think of all the bug guts causing turbulence. You know how I know? I attached streamers to my car after washing it and they flowed so nicely, it must have been laminar.
If I only had a wind tunnel to prove it.
All kidding aside… it really doesn't matter if someone thinks there are gains to be made by wrapping their intake tubes. If they like it and believe in it… who cares?
Some are speculating that the delta air temp while in the tubes is for all practical purposes insignificant, others are speculating to the contrary. I don’t have the time, gumption, or reason to setup a real scientific experiment.
Unfortunately Jim’s experiment, while a novel one, was flawed because it didn’t contain a ‘control’. Basically it proved air temps going into the engine vary. The source or conditions of the variation wasn’t accurately explored.
Two reasonably simple experiments would require two sensors. One could be setup to measure the difference in air temp between entering and exiting the tubes. A second could be set up one tube stock and one insulated then measure difference in air temps exiting each. Short of ‘controlled’ testing like this, the real truth will not be known with any certainty.
Well I suppose someone familiar with the subject could reasonably predict what would occur. I’m sure given the boundary conditions and some finite element analysis; the prediction could be fairly accurate too. That would be less practical than setting up a two temp sensor experiment.
There are some that understand thermodynamic principles and some that do not. I unfortunately had to take that class twice before passing, so it’s not exactly my strong suit. Then again, a lot of people haven’t taken thermo at all.
I have my thoughts on the subject and some don’t happen to agree me, so in that case we will have to agree to disagree.

Looking at the way the tubes fit to the air box and the vents i would say that any improvement was due to the fact that the tubes are been sealed at the joining points and creating better air flow through the tube.I know i have almost 1/2ins gap around my joints.

On just the intakes that shiney stuff makes under the hood look like my attic.
Cover a bunch of other stuff and it looks like some kind of space shuttle project.

Mine were sloppy loose, too. Good tight fit now. Probably the best answer to this question.

which ive brought up regarding this topic for over 10 years now. There is a good amount of vacuum in the air box, when sealed, when it isnt, it leaks everywhere and a lot!! Air enters from all over the leaky pipes and loose filter fit area.
