Anyone have any experience with this stuff? How well does it actually work? I noticed that my intake gets crazy hot since it goes over the valve cover and all that mumbo jumbo. But I dunno if I wanna spend the $60 ($40 for like 3 feet of it, but my intake is longer technically cause it's a 2 into 1 design deal) on heat wrap if it doesn't do anything
I'd say it's a good idea. There is a lot of heatsoak in that particular area, whether or not it is worth $60........ehhhh
from what i hear it doesnt do much because for the split second the air is in there it doesnt heat up and wont make a difference.
You're thinking about this too much...
It's almost like the guys who ditch their jack and spare tire to "save weight and be faster." They must've missed the part where every 100 lbs. = 1/10th of a second. With the money you spend on header wrap, you could almost order a polished stainless steel intake from me that doesn't conduct NEARLY as much heat as an aluminum intake. Just my $0.02, though.
Slightly off the subject but still wraps type question. What about heat wrap for exhaust manifold, or header? Does that stuff really dissipate the heat? It seemed like a decent idea.
i agree could just invest in a better intake from the get go...but i built a custom alim set up and bought the heat wrap for 14 bux..wrapped my whole intake in it...didnt do like dyno test or anything but i pretty sure it helps keep heat away..mainly at stand still idles (traffic etc.)
If you want to keep the heat off of the intake pipes, why not just make a shield that goes under them and keeps the heat from the exhaust radiating upwards and warming them up.
By the look of your intake you made (did you?) you probably have the ability to make a shield for the exhaust.
Just as a side note - I work at a semi truck dealership and a lot of the exhaust has shields around it to dissipate the heat and keep it from directly heating surrounding areas.
i use the DEI stuff. Works great. Looks ghetto but works.
I'm trying my damn-dest to understand why you made a dual intake setup, but I'm coming up short. You take a (roughly) 3" diameter T.B. and are feeding (2) 2" diameter air pipes too it
Excessive? Yep! Extra weight that everyone's so concerned about? Yep! Beneficial? Nope! But hey...to each their own, man.
just drive without a hood then u will cool ur intake.
DRIVE HARD OR DONT DRIVE AT ALL!!!
^^^
and screw over all your aerodynamics while you are at it
i doubt the weight of a small pipe and a cone is gonna even slightly effect the car.
i say....make a metal heat shield... might no be much for hood clearence iny our case though...might be tight for room.

steel intakes will conduct as much as an aluminum one will and due to it being physically denser than aluminum it will retain heat for longer, hence the reason aluminum it used as heatsinks for many things that have heat.
also in ditching the tire and jack, it might not save as much weight, however in racing or hard acceleration the weight being back there works with weight transfer (which shifts to the rear of the car) causing the rear to dip and the front to raise even more.
being a FWD car, raising the front upon starts = NOT GOOD.
so removing the jack and tire might not lighten the car much, but is beneficial merely to keep the rear from dipping as much on acceleration where the force is multiplied a bit since its on the tail end of the fulcrum of the car.
the lessening of "squat" taking force off the traction of the front wheels added with the removal of a bit of weight can actually yeild noticably faster times, even if it isnt 100 lbs removed.
as for the intake sleeve, especially when an intake is in direct contact with a hot source such as a valve cover, no matter the material of the intake, the heat wrap is a good idea, but not really needed. check DEI, they sell a tape for radiant heat which is good, however if your intake is literally laying on another metal source, it can transfer heat.
although in motion not really an issue, but if in idle a good deal, traffic, or at the track can be beneficial.
The header wraps hold the heat in the exhaust keeping the velocity up, which in-turn helps the cylinder scavaging. The problem is it also traps moisture on the header, promoting rust. Ceramic coatings do almost as well at holding the heat, and prevent rust.
As for the intake wraps, they do cut down on heating of the intake charge, but with a 4cyl. you would only pick up 1 to 5 HP over a bare metal intake. For the gain, unless your racing, its just not worth the money.

keep in mind worth is up to the individual.
someone might be looking to get the highest numbers on a dyno they can get for bragging rights... prob would be worth it.
someone looking for a better time at the track than a friend with the exact same setup, might be worth it.
JBodieD. I know that exist some type of paints or fluids that can be applied to metals and acts like a thermal barrier. Also ceramic coating can help about this topic, not too much, exist other better techniques. Right now I canīt find the link, but ASAP I will post it.
Also try to isolate intake tract / TB from head heat.
Event. Hi friend, nice answers. I am glad to hear about you again.
Regards,
