Intake Manifold Thermal Spacers for V12TT - M275 / M275E60
Installation instructions are provided with purchase.
I would like an idea if this is a reasonable DIY project or not, though.
Sorry guys! But I will be waiting with baited breath on Oxygen's install.

I have used them before, whenever I had an engine ripped apart, and can say for a street car I have never seen ANY gains from them.
Two potential drawbacks as well:
1. Posiable turbulance if not size acurately
2. Potential leak source
Also, the engineer in me knows that reguardless of whatever material they are made out of, sooner or later the engine will reach equalibrium. For dragin, that is not an issu, as you have cool down time. For street use, no gain.
Good luck and let us know.
PS: I would love to see a dyno with them, wiat five minutes and dyno again

That would be proof if they actually block ANY heat or not in the real world, aka daily driver.

heat transfer. Even large phenolic type spacers, ie: in excess of 1" thick will only retard
the heat equalization between engine and manifold. All this stuff has been known by us
real automotive engineers for over 40 years. Please do not fall for the hype.
If you seeking real consistent/durable street horsepower available at any OAT, just
make sure that your water-to-air "intercooler system" is bullet proof, with a reliable
electric circulating pump and radiator(s) sized to the amount of heat [boost] that you
are producing. The MB stock system goes wanting in both areas. This was the most
difficult issue for MB-AMG to solve on the SL65 Black Series, hence the HUGE cooling
system with the extreme frontal body modifications to contain it.
