There are some self adhesive thermal sheets available now and I would guess that is what the 3M sheet shown on site is. They seem to work OK for electronic cooling applications, but I cannot see how well in would work in this application or survive the oil, solvents and physical abuse under a car. I would be happy to know if I am wrong, but I would not buy it.

Looks to me like a cheap product with a big name. The idea is heat transfers to the arc heatsink and is dissipated by the open air. Well heat transfer in this sense is based on surface area. It looks aluminum, and the mesh is such a small size I would imagine any effectiveness would be insugnificant. If the fins were a solid material, or even thicker walled hallow core, it would work much more efficient. I would even suggest using copper as a better alternative, but copper is a less tensile and durable metal. If I were to do this, I would get a decent gauge aluminum mesh, and build 2-3 offset layers and physically wrap the lower IC piping with a heat transfer coating. Also a strong heat shield should be in place, as heat-sinking works both ways. It could help the item absorb heat from the turbine area ect. I wouldnt count on this for transmission cooling though. Looks like they had a simple idea that works slightly in theory, and needed some ideas where to use it. (hence the transmission ect.). ARC is sort of dissapointing lately....
Also our transmissions have cooling fins galore already. Install of this type product over such finned areas would decrease airflow to the more efficient solid fins of the transaxle and increase heat within the unit as the incoming air is blocked by the "magic" cooling fins.

a vendor on evom was selling this. i was gonna jump on it then woke up and realized this may be a waste of money. until i see some test (even if informal and not elaborate) would convince me to try myself. unfortunately i dont have oil temp or tranny oil temp gauge but i highly doubt you will see 10-20C drop in temp(as Arc claims) hehe.
yeah i cannot say simply because its Arc i will bend over backwards for it. even arc's cooling shield helps keep more airflow to radiator/IC but its more show then temp reduction. even the Arc ti uicp is a huge waste of money for the couple lbs you loose (compared to other 3rd party uicp).
plus the need for an adhesive layer would severely reduce its effectiveness. for heatsinks on computers, they are metal to metal for max efficiency. thermal paste is simply there to fill in the micro-valleys and imperfections you cant see with your eyes. best contact is always metal to metal only. IF this arc fin can work, it needs to be kept in direct contact w/ an oil pan or transmission housing not via sticker but a frame of a sort to keep it there tight or simply melting the arc fin straight onto it haha
