Get better airflow to your engine with a 3D printed NACA duct made just for your car. This functional intake duct mounts on your hood or fender to pull cool air where your engine needs it most.
The NACA design is proven in racing and high-performance builds. Your duct channels air into the engine bay efficiently, which means cooler intake temps and better throttle response. Whether you run a track car, daily driver, or custom build, this part works with your setup.
We print your duct on demand so you get a fresh part built to spec. No sitting in a warehouse; no settling for off-the-shelf options that don't quite fit. Install it yourself in under an hour.

Designs like this print well in PETG. Compare the materials.
Printed plastic is strong for its size, but it is not metal. We have not load tested this design, so we do not publish a weight rating. Keep it out of a hot car and away from open flame.
