2023+ Honda Civic Type-R FL5 Carbon Fiber High Volume Intake System

• NO ECU CALIBRATION REQUIRED

Technical Notes:

Carbon Fiber represents an exciting new direction for PRL Motorsports. While we have carefully evaluated this material option for some time, we maintained a deliberate approach to its implementation. This new Matte Carbon Fiber version for the HVI shares many of the same overall design characteristics as our roto-molded FL5 air box, with slight modifications to the mounting system and factory seal attachment points.

Testing Data:

This new Matte Carbon Fiber version shares many of the same overall design characteristics as our roto-molded FL5 air box, with slight modifications to the mounting system and factory seal attachment points. Much like to roto-molded version, our testing concluded that the factory rubber inlet restricts airflow into the air box, creating a potential loss of 10–20 horsepower with the hood closed. To address this, we have incorporated the secondary air duct from the roto-molded version to eliminate airflow restrictions. By maximizing the opening size and optimizing airflow into the air box, this design delivers an increase in airflow compared to the OEM unit, maximizing performance.
