Lawman question on heat-wrapping intake

Pretty impressive string over the last few days on methods of reducing intake air temp -- but I got pretty lost after a while.

I recognize that some of the more elaborate methods might result in the most gain, but I am interested in the simple formula of the approaches that lead to the most gain at the lowest cost and lowest effort. In othe words, I con't plan to fabricate hoods and tents, nor do I plan to raid a NASA salvage yard for solar-treated parts. I just want to wrap, tape or paint the most easily accessible parts that can result in real improvements in intake temp.

I also am wondering if the foil heat fabric you can buy at most bimmer shops for the underside of the hood is better than just heat tape for areas like the filter housing where I have some room to install it.

Just to start it off, here is what I am hearing:

Foil wrap or heat paint the whole outside of the filter housing
Wrap all exposed areas of the intake hoses from the filter housing to the intake manifold
Wrap at least the bottom part of the intake hoses from the grilled to the filter housing

Is that the short list?


In simplest form, can anyone summarize what method achieves the most gain in the easiest way -- e.g. simple
