Engine Bay Temperature Reduction Help
 
I don't think I've replaced the engine's air filter in several years and the engine bay seems to stay pretty hot. If I replace the air filter would that help to lower the temp in the bay? Also, would a K&N Air Intake help even better?

A new air filter makes the engine to breath more easily, so lowering the fuel consumption a bit. But i won't expect any change in the engine bay temperature. The engine block will be kept at a temperature around 100 C with the cooling system, so a new filter will not have any influence on that.

Won't reduce the temp no, but it does get really quite hot in there after being driven hard. Doesn't help it's pretty cramped either tho...

Are you talking about the temp that's on the gauges (engine temp)? Or are you talking about the intake temperature?

Different filters and intakes can help lower intake temperature. But it won't do anything for your engine temperature.

If you want to cool your engine bay, make some exhaust vents in the hood.

I don't have an WJ, but I had a Durango and a RAM previously. The best way to reduce underhood temperatures was to remove the rubber seal along the windshield cowling. The downside is that if you run your vents, the hot underhood air is sucked into the vent opening at the windshield cowling.
