Take personalization to the next level with Billetworkz Custom Window Vents, tailored to fit your exact vehicle make and model. Unlike our standard circle-cutout vents, this made-to-order option lets you choose from circle, heart, or cloud designs — plus the choice of with mesh or without mesh.
- The window slides between the inner and outer layers
- The middle layer locks securely into the door frame
- Quick, tool-free install: lower the window, set in place, and raise the glass back up
Once installed, your custom vents stay firmly positioned until you remove them. Use them for better airflow, shade, privacy, or simply to give your build a standout aesthetic — whether at the track, on the street, or at a show.
- Made to order shape cutouts with optional mesh inserts
- Sold as a pair (driver + passenger side)
- Designed and manufactured in the USA
Production & Policies:

No Mesh
Beginning of a new year and one of the top things on my to-do list was to buy a custom window vent from Billetworkz. I had heard great feedback from another car enthusiast and was pleased to see a variety of customization options when placing my own order. The shipment arrived quickly. The packaging was carefully done so as to not damage the window vent itself. I really felt as though the shipping staff took considerable care with their process. Anyway, the window vent fit perfectly in the frame of the window and the spacing of the bottom part was on point so that the window glass easily slid up into the middle of the vent without being scratched. The window vent was well made with consistency along all edges, corners, mesh cutouts, etc. I have kept the window vent installed during highway-speed drives and there's no apparent issues with noise, rattling, shaking, nor dropping, etc. I appreciate being able to provide for a little bit of air flow with these vents - and to do so in style! I definitely recommend Billetworkz.

Jordan Garcia I like how it looks, but I just don’t like the open gap on the window hopefully for future ones they can fix the molding problem to be flush. My window visors shouldn’t be the problem for them doesn’t touches

Emilly Mescall 10/10 recommend this! It's a perfect fit, exactly what I ordered. And very durable. I can leave it in when it's raining and no whistling noise when I'm driving.

Ahmad Almoghraby I’ve had these window vents almost 3 years now , and I’ve never had a single issue with them whatsoever. They are very versatile and easy to install and remove . I usually have them on during hot weather which basically dissipates the heat inside the car , and whenever it rains , literally not even 10 seconds I can remove them so water doesn’t come inside the car. And it definitely gives it an aggressive look to my Mazdaspeed and I get a ton of compliments from everyone . I absolutely highly recommend it to anyone looking for window vents , best in the market.

Gregory Asher Bought these both as a new part of my show car and to provide me with airflow for car camping. They're well constructed and met my expectations exactly. Plus they add a nice touch to my otherwise boring windows!

Sara Rick Solid construction, and they look slick. They fit snugly in my windows. I can use them on the freeway, and they stop the pressure thumps
The mesh allows for nice airflow when car camping. The mesh isnt mosquito or gnat proof, but it works for larger bugs when camping

Becker Geiger Only had it during the hotter days of the season and it is perfect to leave on when parked keeps all of that hot air out and when driving it is amazing! I love it so much, and so thankful for the custom hold that have been made!

Kevin Perrini This piece is great if you’re looking for something different that will turn heads. It’s not over the top where it draws all kinds of the wrong attention however it does get noticed and make people stop and look. Good for venting the hot air out on a warm day as well. I love this mod and should be a must buy on everyone’s list for the VB.

Andrew Stevens Love this vent. Fit and finish is perfect. It allows air in and out without whistling or other wind noise. Also, I've left it in with slight to medium rain and the interior stays dry with the mesh screen installed. Definitely recommend this item.

alfonso piacentini This is the second window vent I'm buying, originally bought the standard window vent a few years ago and then saw that they came out with the Akatsuki cloud design and just had to get that one. I love it looks great on my car.
