Sikky Thermalnator Gasket

Here's what the website says:
Thermalnator is a unique high temperature shielding gasket which replaces the stock intake manifold gasket. Thermalnator's cooling properties reduce heat by stopping metal to metal contact between the intake manifold and the engine block. By using a Thermalnator gasket, you will reduce the heat of the air entering your engine, making up to 5% more power. Thermalnator gaskets allow the intake manifold to perform like an intercooler. Because the manifold is no longer heated by the cylinder head, the heat from incoming air can dissipate through the aluminum very rapidly. The basic formula for this is for every 5 degrees F increase in intake air temp, air density is reduced by 1%. The denser the air is, the better the gain in horsepower.
Average testing has shown an 25 degrees F drop and up to 35 degrees in some applications. This is why a Thermalnator gasket is an excellent upgrade for your vehicle if it's stock or modified.
This weekend I will be installing the part and testing with a Digital Thermometer (Raytek MiniTemp).

Stay tuned!

Ok, here's the results of my drive home on the OEM gasket:
Heat Soak Temp: 144*F
![](https://www.miataturbo.net/attachments/engine-performance-56/17578d1279407611-sikky-thermalnator-gasket-heatsoak144f.jpg)
Head Temp: 187*F
Manifold Temp: 148*F (no picture)

(Heat soak was measured by popping the hood free of the "catch" and leaving it closed. I aimed the digital thermometer into the engine bay. Not scientific I'm sure, but gives you an idea of underhood temps)
Part Two: Sikky gasket measurements COMING SOON!

lots of honda guys use this same stuff but made by hondata.
its "supposed" to help.
no one knows how well though.
I think a nice efficient intercooler or w/i or e85 would provide results 1000000x better though.
I hope its cheap, cause anything over 40 bux for a gasket of that type is highway robbery

I doubt it, but I am using a plastic one that blocks off the water ports on the head.

...also, Hondata makes one of these for our cars, but when I was shopping around, the Sikky gasket uses a type of plastic that has a higher temp resistance rating. In reading, a lot of people found the hondata gaskets would deform. I don't plan to get that hot, but for the same price as hondata, but higher temp resistance; it was obvious which one to get.
*I can't remember all the techie stuff on the fly...I'll look it up and see if I can find the info that I found.

If the head gets hooter than the intake, and you can separate that...wouldn't you think that'd yield a benefit. The engine bay cooler than the head is; at least I would think.
Again, I'm going to be testing and we'll put this to bed along with theories. Either it'll work, or it wont. We'll all see very soon!
The hardest part of this project is getting off my *** to get it done.
