Does anyone have one of these or can provide feedback on them working to drop temps? I haven't seen much about these. I figured since I am going to install an 18 manifold, it would be a good opportunity to put one on if it works.

personally I don't see a lot of heat transfer happening with the plastic manifold....especially with the velocity of the air moving through it. Steeda makes some quality parts(I have some) but this looks like snake oil to me.

Up to 12whp gain

Yeah... doubtful. About as believable as putting on a CAI with no tune and gaining 15 whp.

This. First of all, plastic isn't that big of a heat conductor and second, the air is moving so fast and has a very very small window to absorb heat while in the manifold.

Also, there's no temp sensor in the manifold so the computer will not see any decrease in air temps from this to adjust for with more timing...thus even if there were any actual temperature changes there won't be much power associated with this all since the timing would remain the same.

Save your money for other mods, like those which actually help get cooler air to the filter.

For anyone that wants to try something like this just get the DEI stuff. basically the same thing but you have to trim it yourself. Half the price. http://designengineering.com/reflect-a-cool-heat-reflective-sheets/
Still think its pure snake oil though unless your sitting and purposefully letting the engine heat soak for 30 min.

Can you specify both types of tapes you used, only because there are a lot of different double-sided and aluminum tapes out there...?

Regarding my above comment, quoting from @Kahboom, can anyone speculate about what tapes are being referred to? I don’t have much experience with this sort of thing.

3M double sided grey tape, 3M or foil aluminum tape, both can be found in any hardware store.
