The best theories are tested by alternate proposition and argument. On that, they stand or fall. Consequently, many of us have abandoned the notion of a flat earth .

"The temperature of a gas is a measure of the average translational kinetic energy of the molecules. In a hot gas, the molecules move faster than in a cold gas; the mass remains the same, but the kinetic energy, and hence the temperature, is greater because of the increased velocity of the molecules. " ( NASA)The increased molecular velocity is the reason for the increased gas viscosity that inhibits flow. (See first link)I'm out again

Manufacturers wont do it due to cost, ...
There's the basic principle of keeping your incoming air as cold as possible, since cold air is dense air. The denser the air, the more oxygen you're feeding the combustion process. By concentrating the heat within the exhaust manifold and minimising the heat leakage using the wrap, you're giving the inlet manifold and surroung intake path the best chance at a colder environment.
One of my mates is getting a very good crowd in Longford Tasmania to ceramic coat his custom headers/extractors inside and out on his supped up Skoda Octavia.

Thinking back I wish I'd had done mine too though costs were blowing out with the modifications I had done so I skipped it
I used that wrap on my Harley once but I never saw 1 mph entrap speed gain or 1 tenth in time quicker it was the same with or without. but I tried a different set of pipes, on same bike same day and saw a 12mph trap speed gain and 5 tenths quicker time.
that bandage only works for mummy's.

She's still undercover. Really hard to find a good 2.8L replacement motor. They came out with bigger M3 motor in 2001-2 so looking for any Bimmer writeoff with that in it. Will be a fun motor, loom and ?? ?? change over.Stay fit pal
