There are quite a few of the PS hood vents in this area, and in an effort to not just follow the pack I chose the Rugged Ridge hood vent. Good quality and straight forward installation.
I also went with the Rugged Ridge hood vent, one corner was a bit bent up during shipping but straightened out just fine. As said above, easy install!!

I was also looking at poison spyder's vents. Any issues with cold weather with ice and snow. My jeep is my dd.

The sheet metal is so thick on those old Willys compared to the JK. I'd hate to get hit by one!

I like mine. They cost a total of about $20-30 for both and really complement my Bushwacker pocket flares. Living in San Diego and wheeling all the time in the desert I never had any issues. I also have a SC and Transmission cooler under my hood...

I, too, would recommend the Poison Spyder louver. Installation is easy, and you can have it painted or powder coated to create whatever custom appearance you want. I love mine!

I have always believed vents in the windshield's high pressure area has the potential to reduce air flow through the radiator. Someone posted they checked it with little paper streamers on the vents and verified air does actually flow out of the vents at road speeds.

Can we get a few more people to run some similar tests on hood vents installed near the windshield? No one I know locally has hood vents.

Ron, did they mention where they attached the streamers? Wind going across the vent does not necessarily translate into air coming out of the vent. The wind force going across the vent could easily overwhelm less wind being drawn into the vent. I would like to see the streamers attached underneath the vent.

And I agree, more tests would be great.
