Category: Window Vents

Customize your ride with Billetworkz Custom Window Vents, made to order for the vehicle you select. Precision-engineered for a vehicle-specific fit, they improve cabin airflow, help reduce heat buildup, and add shade and privacy. Unlike our standard circle-cutout vents, this custom product lets you choose from Circle, Heart, or Cloud cutout designs, with the option to add an aluminum mesh insert for extra protection and a more aggressive look.

The layered design allows each vent to fit securely within the window opening and remain in place until removed. Made from durable materials for everyday use, Billetworkz Window Vents deliver a clean, secure fit for daily driving, car shows, or track days.

Includes one pair (driver and passenger side).

Customer Reviews (4.8 / 5 · 5 reviews)

Kevin I. ★★★★★

The precision fit on my specific car model was spot on—no gaps or rattling at all. I’ve noticed the cabin stays noticeably cooler on sunny days with these vents directing airflow better than the stock setup.

Steven Y. ★★★★★

Driving with the windows down used to be unbearably hot, but these vents actually channel the air in a way that keeps the cabin noticeably cooler. The vehicle-specific fit was spot on, no gaps or rattles at all.

Alexander ★★★★★

Installed them on my sedan last week and the precision fit was spot-on—no gaps or rattling. Cabin airflow is noticeably better now during my afternoon commute.
