They are functional at releasing heat. More to the point, are they really necessary? Where I live we have snow on the ground. Around LA? maybe. My TJ has never even come lose to over heating and when it hits 40 below I want to keep all the heat under the hood I can. Very common to see cars, trucks, Jeeps with a tarp from the hood to the skid plate during winter.
You won't gain anything at all from a vented hood other than looks. It may be functional under the most extreme circumstance, but that isn't going to be driving around town, even in Phoenix.
The stock TJ cooling system is more than sufficient at keeping the engine cool.
X2 to Chris's comment, your engine won't even notice that you added hood vents. I wheel in the SOCAL deserts and if hood vents served any useful purpose I'd be running them.
Nope, not at all. Jeep designed these things to run in those kinds of temperatures. The best thing you can do is just maintain your stock cooling system.

Won't really lower engine temps but greatly reduces under hood temps. I killed a compressors because the under hood temp was too much for it.

How did you manage to diagnose your a/c compressor to definitively prove nothing but underhood heat caused its failure? Not many would believe our a/c compressors will fail from exposure to typical underhood temps.

I installed GenRight Hood louvers, it does help release the accumulated heat under the hood. On a hot day in Southern Nevada I run 207 degrees, down from 211, and the heat dissipates much quicker when at a idle. Besides they look really cool.

I actually like the look of those. It's subtle, not too extreme like some of the vents I see.
as opposed to this.... $290.00 for a dif cover ??

Can't blame you there. If you already need some bodywork on the hood it certainly would make life easier.

I meant my on board air compressor to fill my air tank for tire inflation and air tools.

I've been building cars since the 1960s...never knew a build that didn't need deep pockets. The builds I see today are far more advanced than anything we did in the past...just saying.
