Heat under the Hood?

[bigbadxj]

I know there has been a lot of arguing about cone filters and homemade inductions about how they just suck up hot air. But I was figuring since the intake and exhaust manifolds are right on top of each other the air is going to be super hot before combustion anyways right!?! Also everyone wants to know about headers, but isn't the stock exhaust manifolds almost like the aftermarket headers maybe just not as long but over all it has more of a header design than a lot of exhaust manafolds that or really badly designed. So My point is wouldn't taking off your stock manifold and sand blasting it and having it cerimic coated or rattle can coated and then wrapped be the best way to reduce heat in that area in turn making for more power and better running Jeep? Huh HUh what do you guys think?
