Intake Manifold Heat Shield

Is anyone on here running one of these shields? Do they really work and decrease temps?

It does. I have heard a little bit about it, but I'm not sure if it would really work. It might be worth a shot for 50.00

It's worth a try anything that can deflect heat away has to help. My car is apart I'll buy it and will see.

I think it won't make much of a difference.
I mean the intake is bolted to the heads. And it's plastic anyway. It only absorbs so much and I'm sure the heads send the most heat into it. I think an air gap is just as good.
Seems it will only block heat radiation. And how much does the valley cover give off anyway.
One of those things that wouldn't hurt just may not be needed.

I was thinking the same about the heads.

I see that. Would be cool if it was true. That's why I'm thinking it would be worth a shot for 50.00.

I think the 12hp is bs
I'd have to see the proof of that one.
Id say it's worth buying a piece of heat shield and cutting it to fit for $10 over this. Unless you don't mind spending the extra money.

Heat soak is heat soak. It may allow it to take longer to soak, but soak it will! Let's put it this way... There are MANY cars running 10's without one.
