I agree the over the manifolds would be the most efficient. The vacuum effect is what "pulls" the hotter air out of the engine compartment so location is ideal but not necessary. I would love to have put mine there but with the hood bracing it was not feasible.

Take the hood insulation off. Than you can see the bracing for the zj hood Locate in between the bracing. This is pretty easily found. I located mine approx 2.5-3'' from the edge of the hood. Mine were angled cause of the hood lines. Go out and look at your hood take a picture if you have any other problems.

ratmonkey interesting stuff !! iat relocate ? air hat ? catch can on pvc explaine please more info needed,
Intake air temp sensor gets heat soak from being mounted in the hot intake manifold. Relocating it to a bung on the intake tube gets it reading real air temps.

The pcv sucks a lot of oil mist and deposits into your manifold, which goes right into your cylinders after gumming up everything else in the way. A catch can or even a 3/8" push on fuel filter pulls the contaminates and oil out of the air helping keep your motor cleaner and retaining the positive venting action instead if just using two breathers.
The air hat is the part of your intake assembly that bolts to the throttle body. On v8 grands it is the most restrictive part of the intake system before the heads. On ram trucks the hood height above the motor is greater allowing a much taller air hat to be used. With some minor hood brace trimming and/or spacing it up a bit.(another trick to help vent heat is to space up the back of the hood, but it doesn't look as good as vents).

Use insulating hvac duct wrapping(foil backed tape too) to wrap all fuel lines in the engine bay and the intake tube. Those can add a pretty decent amount of pep. The engine was initially programed to run without all the heat soak the fuel and air charge take up. Eliminate it and the motor will run much better.

With these tricks you'll all be mustang killing machines.

You'd think, I've found the most effective way to vent the stock(unwrapped exhaust) bay is to have you vents just behind the rad/fan area. The manifolds get hot, but convection and the vac effect doesn't get that much heat out of that area.
Keep your vents forward, scoops middle, and raise the back of the hood for either method.

'97 zj 5.2, some stuff, some other suff, and some things that even work sometimes.
