Heat sheilding the air intake covers??
I have seen a few here as well as other sections (E55,CKL55,etc...) use that foil heat sheild stuff on the air intake housings.
What caught my attention was linuxfoo's post showing the underside of the air box covered in heat shield tape.
The idea makes perfect sense as the manifold is directly under this and probably throws of a good amount of heat for the air box to soak up. I am considering doing this to my car as I will be changing over to a set of green filters soon.
A concern I had was where does the heat go?? If it was reflected by the heat sheild tape then it would likely be directed enventually to the upper side of the engine bay as heat rises correct?
Also, there is a small gap between the air filter housing and the manilfod which is most likely usefull to disperse heat. I am not familiar with this heat sheild tape's caracteristics and if it is a thick material then this "gap" would be closer and would it be possible that it may trap heat? Now that the gap may be smaller, heat is more likely to be trapped below maybe creating the same or higher temps as original??? Actually, aside from thickness and air space would the reflective properties maybe direct heat back at the manifold causing higher manifold temps???
These few scenarios have me thinking. Has anyone done any temp. testing to see if the results are of value??? Not even sure how one would go about testing these temps... :p
Those with experience please tell...
I have an infared temp gun thing(brother's in HVAC) so maybe I could do some testing by shooting at certain points before and after installation of heat sheilding.

hey nitro, your thought process is pretty deep and appreciated, when i first did this mod awhile back, i only thought about reducing the inside temp for my air box and did not even think about the end result of the heat that may arise by reflecting the heat back to the manifold. during freeway speed, this might not be too of much of a probablem, however, it might during stop and go traffic scenario where there might not be enough outside air passing through the engine bay. it would be a good test to check the temp with an infared temp gun of the airbox with a modded one vs a non-modded one during idle and freeway drive and maybe day and night scenario as well, it would also be good to check the manifold temp on both. i am open to test this scenario in the BAY AREA with someone that has a stock airbox, we will also need an infared temp gun. anyone interested? this will provide valuable information for others to decide whether this is a good mod or not.

What was your conclusion bud????
Linuxfoo, I could do testing on my stock setup before installing heat sheild and then test temps afterwards. The downside is that I will have to depend on identical weather before and after installation.
I'm determined to find the answer to this.

yeah, ideal scenario would be have two cars follow each other and test, that way we get a more accurate figure. but if you plan on doing the thermo-tec, measure temp before and after perhaps even just to get some figures. also the heat shield does not touch the intake manifolds, there still is a gap between the two. thnxs Nitro.
