Heatshield products on gt350 intake manifold

[BLUEIVYS550]

Is anyone use the heat shield product on their gt350 manifold. I'm curious to see if and how much it lowers inlet air temps and how much does it help or hurt the car. Supposedly it kept the car 5-10 degrees cooler and it gained almost 9 hp on a gt350, so I'm wondering what I'd do on a regular gt. Hopefully the same.

I will be making my own to install on the Holley intake if it ever arrives.

I've only found it at summit for 89$ plus shipping. Seems steep for what it is. Maybe a forum vendor will start to sell them.

If it does what it says. Notice I said IF. Then for IAT to run 5-10 degrees cooler and gain 8-12 hp from a cooler IM while helping prevent heat soak. $89 is relatively cheap for what it does. That's a 3rd the price of a CAI and extremely cheap compared to an exhaust, which will get you the same amount of hp (without a tune) as this simple mod. Not necessarily comparing apples to apples but you get my point

A dollar a horsepower seems like a bargain. Cooler air is always good.

Maybe in the Fall. lol

I am going to try the DEI reflective sheet part number. It is a 24" x 24". It has a peel and stick backing on it. You can find it for about $29 online.

I actually bought their 36" x 48" sheet. So I can also wrap my air box and intake tube.

That's what I have.


60.00 for someone to cut it.:frusty::frusty:

Thinking of doing this, how easy is it to remove the stock intake manifold, put this heat shield on and then refit the intake manifold? Anything to be careful with or any general hints for the removal and re-install?

Just got this for my 350 IM install(among other things).

While the product itself works at blocking/reflecting heat, I can't imagine that it does anything to the performance of the vehicle it's installed on.

For one, the computer will not be able to see any drop in IAT temps from this (to say add timing) as that sensor is in the MAF itself and thus not affected by this. Second, the incoming air travels are very high speeds, so it will spend very little time in the manifold itself and thus won't really have time to absorb heat. So while the manifold plastic itself may run a few degrees cooler, the air going into the head runners won't be affected at all by that reduction in the manifold shell temperature.

So I can't really see how this makes any sort of meaningful or measurable gains on a dyno unless the car is setup with an IAT2 sensor like in supercharged cars which may see a degree or two difference in temp and thus add another degree of timing for 2hp gain if that.
