PRODUCT OVERVIEW

Introducing our 3D-printed headlight intake duct, designed to replace the factory headlamp and provide a direct path for cooler outside air into your engine's intake system.

By replacing the factory headlamp, the duct is designed to significantly reduce intake air temperatures while retaining useful lighting functionality.

The integrated lighting system includes:

LED projector headlamp
High-beam functionality
Daytime running light
3" intake outlet
WHY ABS?

Unlike many competing ducts that use lower-grade materials that can be prone to warping, our ducts are manufactured from high-quality ABS.

ABS is a proven automotive material widely used by OEMs for engine-bay components because of its heat resistance, durability, and dimensional stability.

For 3D-printed components, proper printing is equally important. Properly printed ABS provides excellent interlayer adhesion, helping produce a strong and durable part capable of handling the conditions found in an engine bay.

ASSEMBLY & WIRING

Final assembly and wiring are the responsibility of the buyer.
