My recommendation would be to first wrap the aluminum tube with some thermally insulating tape, like exhaust wrapping tape, and then wrap the outside with some shiny aluminized tape, since aluminum is more highly reflective than gold.
Will try !
Tested it brought intake temp down 10-13 degrees on my 19 Impreza! Thx
Reflective blocks radiation heat from the sun UV etc. it reflects so it bounces off. An engine bay puts out convection heat not radiation. I wrapped my intake and the heatsheild in the fiber wrap they use for headers. On a Supercharged Audi A6 I saw a consistent 10 degree difference.
I don’t get how that makes sense, header wrap is meant to keep heat IN not out, so you’d think that any heat you accumulated inside your intake tube wouldn’t be able to escape since you wrapped it using header wrap
Heat coming off of the engine is emitted via infrared radiation. The sun emits both Ultraviolet and Infrared radiation. All forms of energy are on different parts of the electromagnetic spectrum.
@@jamest2544 i think it's the same difference isn't it? Heat in versus out...the whole point is it's creating an extra layer or barrier for the heat to pass thru. Given molecules of air spend less than a second inside the intake...not going to make much difference either way(except this gentleman's audi was FI. Didn't mention IC ....so....?? Good question lol. I guess less than second for NA cars...FI would be longer(still IC? matters)
@@jeremygalloway1348 yeah not sure that’s just what I had read online but I figured it would be the same thing too
@@jeremygalloway1348 yeah your right, header wrap is meant to insulate so you’d actually keep the air inside the intake cold and it would prevent the heat of the outside getting into the intake, it wouldn’t really be heat in the inside of the intake not being Able to get out
I think we also need to take into account the potential error of using the gaff tape. Gaff tape is a thicker, cloth style, tape that could potentially be creating some sort of insulation (unless you put the gold foil over the gaff tape, but if you took it off then that could be the error).
Do the same experiment with a turbo car and preferably with an intake pipe that is closer to the engine (one that runs behind the engine, etc.). A comparison between a stock, matte black plastic intake pipe vs having it gold wrapped would also be appreciated!
Kudos for recognizing mistakes and making it better!
I’m getting a distinct tv meteorologist feel here😂
Lmaoo
thermal conductivity has more of an effect than the Infrared Reflective effect.
Experiment needs to be re-run with a turbo car, where as you explained the turbo intake pipe goes over or around the exhaust manifold to turbo inlet - this would give a better representation of the materials' ability to reflect radiant heat.
Hoping to maybe do a repeat with the supercharger.
My intake in my Altima is right over the upper radiator hose.
I wrapped the intake and using the torque app i noticed a drop in intake air temp by 10° alone. While in traffic it gets as high as 140° but cools down a lot faster than with no wrap.
It would get to between 15-20° above what the air temp reads at the dash in normal driving. Highway driving at 65-70 it gets just over 10° of the air temp.
Then i thought what if i also insulated the upper rad hose. So i used the bubble wrap the tape came in and lowered the temps 10° lower in normal traffic and to within 5° at highway speeds.
I ended up insulating the rest of the intake with a silver bubble style windshield sunshade.
Next i plan to do the air box itself in 1/4” foam deadener then gold foil wrapping it.
You can’t use an infrared thermometer on your tape with lights on it. Try this with aluminum in the sun, it can give you terrible thermal numbers compared to actual surface temperatures
Which is why I had tested the back of the tape where there was a matte surface.
The best way to put it on is is not to continually wrap it around. Cut one piece that is big enough to go around intake tube circumference, then cut another piece and do the same thing repeatedly slightly over lapping tell wrapped.. the tape likes to go on straight and it does not like to wrap around like a ace bandage!!!
The infrared thermometer will read different values depending on the material you're measuring the temperature of, so this a potential source of error. A better test would be to sandwich a thermocouple between layers of tape.
I wrap dry ice on it and it gives me 100 horsepower
Why such low numbers?
Ha, I fart on mines and I get 1,000 hp and if I put a sticker on it I get an extra 2,000 hp for a total of 3,000 hp holla 😂
You should tested with the pipe before any wrapping aswell. Wrapping on the black wrap will store heat which comes through the outer wrap😊
smart thought 🤠
Um… that’s not how stuff works inside a dark box. All of that only works with you standing in the sun getting direct sunlight.
At 6:40 dude this is what I like to see. Straight up technical details. Awesome video!
Your small IR temp reader does not have radiometric software, thus you cannot accurately read temperature with reflective materials that have a low emissivity.
I'm wrapping with 10 mm concreting foam then a bitumen based aluminum flashing. Then a silver highly reflective tape. Insulation on Airbox as well. I have to also make a diy heat shield. Any comments or advice would be greatly appreciated cheers from Australia just subbed.nice work 🙂👍👍👍
From what I understand, that gold tape helps keep the heat from radiating, however it doesn't reflect heat like foil backed or foam insulation would.
My gen 3 long tube intakes have crazy amounts of scratches and dents, wrapping them in gold to freshen them up, thanks for the great video 💯
Awesome video, deserves far more views!
Your videos are super informative. Thanks for your efforts! Fellow 370z owner here :)
Glad to hear!
If its hidden from engine heat and direct sunlight you want it matt black, if its exposed to a heat source it needs to be shiney or insulated.
Your not gonna add bhp++++ but we all know what a car feels like when its heat soaked and starts to flatten out on a hot day. Cold, cold, cold is good, but you gotta do it right.
mate. I am glad I found you. Keep it up! great content
Thanks, cheers!
Woven fiberglass + alumunium tape works
you get a like just for you principals
taking a video down cuz you were call out on the test respect
What if you have a powder coated (not polished) alluminium pipe? is it good to wrap it?
U know the answer for this time?
great content, keep it up :)
My intake is black so would it help a lot ?
IAT also gets influenced by heat soak through the intake manifold. Likewise the intake tube can suffer from the same heat soak. If we can battle this heat soak as much as possible before the intake manifold, intake air temps will be low but you have to remember the heat soak starts at the engine. Even though the velocity of the air is high moving through the intake system it is still absorbing the heat (think heatsink).
Heat soak to the intake manifold is prinarely through conduction though as it's mounted to the block. Wrapping the intake manifold doesn't protect against this.
The intake manifold's proximity to the block does however make it a better candidate for IR absorption but it wouldn't be possible for me to practically measure the intake temperatures at the cylinder head.
@@thecarizon504 absolutely correct but heat soak through the manifold could be buffered via a composite spacer. Wrapping of the intake manifold will not show any improvement. Isolation of any heat soak through the intake piping is more so what I am talking about. I'd be more curious to see if you could isolate the IAT sensor from heat soak and see what the gain would be.
Since you have a 370z, would the fiberglass & aluminum heat sleeves help my intake temps if I have gloss black injen CAIs? (I have long tube headers w no wrap or shielding)
Ask yourself, why does NASA use Gold reflective material.....
Because it does reflect. I showed that in the lamp test.
@@thecarizon504 Right I was just making your point more evident to some people who may think that it doesn't work.
Good work
Interesting, I have a Jeep 258, not high performance, lol. But people put hood vents and stuff on to keep their engines cool, cause while we don't run down race tracks, we hit heavy revs and utilize TQ while crawling, so yeah, heat can be an issue. I thought about the gold wrap, but have an Aluminum intake, may try polishing it first. Thanks!! And Sub'ed!!!
1:30 More oxygen? But isn’t the amount of air limited by the inlet size and filter condition? Surely oxygen doesn’t magically appear inside the intake pipe.
I don’t mean to be snarky, please correct my misunderstanding for I am genuinely curious.
Density. Meaning there's more of something in a certain amount of volume
@@CozyKG my question in regard to the “more oxygen”. The air has already entered the pipe, he’s saying the sections covered by the tape would have more oxygen than the areas before then.
Take a box of 1lb air and 1lb air. Then heat and cool the other. Wouldn’t they both have the same amount of oxygen.
Wouldn't reflective insulation be better anyways?
I would like to see some Dyno results or some in car monitoring while driving next time, Good video!
Why don't you just wrap oven Mitten material around intake tubes that will block Heat! Duh! pretty sure the reflective tape is something very similar that's inside an oven mitten!

His tests are inconclusive, over-analyzed, and somewhat disorganized. He tested the black tape w the radiatoe fan kicking in etc, but no chart w the gold wrap.
bruh needs to sum up his results in an summary at the beginning cause im not watching this whole vid to answer a yes or no question
You seem like a great honest guy, but you muffed this test up in so many ways lol. Gold wrapped works. Polished aluminum is great but gold is nearly as good.
Any data to show proving that it worked? Also any comments on how it was muffed up?
I also like to hear how this was "muffed". You state that "Polished aluminum is great but gold is nearly as good.", that is what I got from the video with the caveat that it's under particular conditions.
Thank you
Just do Titanium
Thanks for the review.
I wonder if there’s a way to cool your air intake (without damaging anything of course) with a small amount of liquid nitrogen. If you could get intake temps down to say -20 F inside the air box that should significantly increase performance.
When you mix cool and hot air. Does not matter if they are separated by any piping, it will create condensed air.
They make double wall intercooler piping with fins between the walls. You could drill and tap and hook up paintball tank. Just drill a small drip hole on bottom so it doesnt overcharge. The gas will just flow out and cool pipe and no pressurize. If you tap that drip hole and connect a hose and mount it to vent on the intake manifold to help cool it too.
It's called water/meth injection
Interesting idea. Thanks, I’ll look into it.
A cool can with dry ice. Used in Australia for drag racing.ive tried ice and it felt crispy. Imagine dry ice? Stays colder longer.
Wouldn't silicone spray painted or wrapped do a hell of a better job since u can literally pour liqiud lead on to it with the casing silicone artist use.
Thanks great info!
Is the gold wrap youre testing DEI?
Heat wrapped exhausts destroy headers by trapping moisture and increasing the stress factor on the steel plus they add a fire hazard. Its tech from the 60s for exhaust scavenging we now have engines that are far more efficient than back then, can we all stop doing it.
How does moisture get on headers
@@Mr.grubby unless you have a completely sealed engine bay... (which no car has)... then either from ground spray or through the atmosphere. I consulted with Racers and professional ceramic coating companies (not knock-off ones that just blast and spray them with paint), which wouldn't even take my money to do my stock headers (and cheap stainless will fracture over time and wouldn't be covered under warranty).
They all said, either get a high grade stainless and leave it alone or leave it stock, the returns are worth the reward.
This is no longer true DEI has a silicon sealer to prevent moisture build up. Also the wraps have a life span of 4years depending on the environment it’s run. Further 60s cars leaked oil by design because emissions were not prevalent
prove it. all the 5 cars that had been with me were all wrapped for 4 years since i replace cars every 4 years and before i sell it i make sure to turn everything up to stock configuration. all my headers were fine after unwrapping the thermal wraps.
Very educational video. Thanks a lot dude 👍🏾👍🏾
When I wrap my temp intake go down around 37 !Fahrenheit. .
Super cool video
Do temperatures run lower than the stock intakes?
Haven't made that comparison yet.
Thats subjective. How poorly designed was the stock intake and is the new one you put on high quality? There are lots of cheap "cold air intakes" out there that have no heat shields and very thin tubing.
My Intake temperatures run up as high as 174°F on Idle in heavy traffic in 90° weather 😢
Driving consistently at around 60mph would give better temperatures
Very good thank you.
discount engineering explained
Black is better in this case because a black body has a larger emmisivity, which radiates more energy of the form of heat.
Powder coating is the best
👏👏👏👏👏
Totally bad scientific doctrine, keep it up.
Thanks for the great content
My engine makes radiation? 🤢☠
j/k lol.
People who use the that are just ricers
engineering explained 😎
@MotoMatt Its more or the same as "Engineering Explained"..Its like Rob Dydrict copied Tosh.O
So I didn't realize that Jason wasbthebonly one in the car community allowed to do lectures in front of a white board... 🤔

To Simply Put it, The Gold Wrap is Rice
So 300,000$ cars are rice?
No No No... You got it all wrong!
Gold tape has nothing to do with heat deflection or whatever...
It just looks cool and is cheap :)
