Bring fresh air into your 2013+ Ford Focus ST / RS while keeping rain, dust, and debris out with Billetworkz Window Vents. Precision-engineered for an exact fit, these vents deliver both function and aggressive style — perfect for daily driving, car shows, or track days.

Each vent features our signature circle cutout design, with the option to add a aluminum mesh insert for extra protection and an even bolder look. Choose the setup that matches your build.

Built with a three-layer construction for a secure, rattle-free fit:

• The window slides between the inner and outer layers
• The middle layer locks into the door frame
• Tool-free installation: simply lower the window, set the vent into place, and raise the glass back up

Once installed, the vents stay firmly in position until you remove them. They enhance airflow, help reduce cabin heat, and add shade and privacy — all while giving your Ford Focus ST / RS a clean, performance-ready appearance.

Made from high-quality PMMA plastic, Billetworkz window vents are durable enough for daily use and stylish enough for any build.

• Circle cutouts with optional mesh inserts
