JK Fender Vent inspired by the JL Fender Vent

I really liked the new fender vents on the JL. Jeep claims the vent is to reducer hood flutter. But that also means it reduces heat via the air being exhausted to cause that effect. I actually debated about sharing this because flack from the traditionalist on Jeep appearances but I know this will not please everyone so I will go ahead and share.

So I went looking for something similar for my Jeep. Of course with the JL recessed grill it was not going to be the same. I searched and searched for something that would work and look good. Finally order a set of grills that I felt would work out great. After I got them I changed them from carbon fiber/chrome appearance to textured black and red. I have red accents throughout my Anvil Jeep so that seemed natural. I bought an air nibbler to cut the hole into the fender. Being a retired tech ed teacher I have used nibblers during the 8 years that I taught metal shop. The nibbler does not distort sheet metal like almost every other tool you might use to cut the hole. The sheet metal on the JK is so thin that just drilling the access hole for the nibbler distorted a large area but luckily totally inside my cutout.

So next I had to decide where to put the vent. I tried two locations and bounce the positions off some friends. I preferred the higher of the two since I did not have a vent shaped like the JL. So I marked off my location and went past the no turning back point by drilling the hole. The nibbler worked awesome and the hole was open in a couple minutes. I filed the final hole and painted the exposed edges. I covered the entire back with 3M VHB (Very High Bond) foam tape. I applied the grill to the body and it stuck like crazy. That is great adhesive tape. I repeated the other side and I had side vents. above the vent location is a recessed area of the fender that worked out great for ventilation and in front of the vent is the back of the black fender inner fender so it also creates a good air flow. So after the install and driving it a few miles I can tell that it is working even better than I hoped. The sheet metal in front of the vent is very warm to the touch and not very warm to the touch behind it. Anyway I like the appearance and the additional venting of the heat. This in conjunction with the Hard Rock hood vents that I also open up underneath should be an asset for the Jeep.

Let know what you think. Good or bad. Like I said I know it is not a modification for everyone.

Took some balls to cut that fender—no doubt. Cheers to going all the way with it and not just sticking a fake vent on there. :appl:

Top notch job right there!!! I get the most hood flutter when I go on our local 2 lane highway and wind her up to around 60 or 70 and then have a semi pass me going the opposite way. I would love to know if those vents would help with that type of rush of air that causes the hood flutter I see.

Well, you did say good or bad ...

I like the functionality, and I give you lots of props for cutting into those fenders. Anything to let the hot air out is a good idea. But, the vents just look tacked-on to me. I think I'd like the look if it were a low-profile metal mesh vent that was a shape that looks like it was intended to be there. Hmmm, now you've got me thinking ...

I would never do that to my Jeep. Mine is perfectly fine the way it is. I'm all for mods but nothing permanent that's largely cosmetic bling. The big gaping hole also further weakens the already too thin sheet metal.

It's your Jeep though so what I think is irrelevant.

I like it, might like 'em more body color or without the red, but I get what you're doing. Definitely like the originality and guts to cut the fenders. One of those mods where you get to that point of "well, this better work 'cus there's no turning back now" :). I like these creative mods better than the "look what I just bought and had installed" ones, but that's just me.

I (giggle a little) when I did the Hardrock hood vent mod ..... I would have thought I killed a puppy when I read some of the comments and all I did was "open" a vent that was originally designed to actually be - Open.

This mod took some cojones... no turning back on this one. With mine, at least I could order another set of vents.

Where in Lancaster? I'd be afraid of road grime and salt getting into the openings and rusting everything from the inside out. But you did a great install!

I like the look of the Landrover vent BUT... Those are so big, whoever the owner was, had to delete their antenna location to install them.

The OP's vent looks good and does the job without sacrificing anything else.
