Together, these pieces work in harmony to significantly reduce turbulence and pressure drop, delivering up to 31% more airflow to the turbocharger.
Designed and Engineered In-HouseUsing in-house Creaform 3D scanning equipment, Unitronic Hardware Engineers capture exact dimensions of the engine bay and surrounding components, enabling them to design parts with millimeter-perfect accuracy. This data is imported into advanced CAD software, where components are rapidly prototyped and 3D printed for test fitting and validation. The result? A direct bolt-on solution with OEM-like fitment, no surprises, and dependable performance.
