  • Improves throttle response.
  • Airflow rating is 78.6% improvement over stock
  • Larger internal diameter (for both inlet and outlet).
  • Smooth unrestricted flow designed using Computational Fluid Dynamics flow simulation software.
  • Lower EGTs.
  • Fits any intake that utilizes the stock location.
  • Also known as LLY intake horn
