PRL High Volume Intake System – 2023+ Civic Type R FL5 & 2024+ Integra Type S

Increase airflow while controlling engine-bay heat with the PRL Motorsports High Volume Intake System for the 2023+ Honda Civic Type R FL5 and 2024+ Acura Integra Type S. Developed from PRL’s previous FK8 intake experience, this enclosed intake system combines a large 6-inch cone filter, rotomolded HDPE air box, revised inlet ducting and smooth airflow transitions.

The system retains the factory front air duct and hood seal while adding a secondary air inlet intended to reduce the airflow restriction and air starvation associated with the original duct arrangement. PRL states that its revised inlet design provides 133% more airflow than the factory unit. :contentReference[oaicite:0]{index=0}

Vehicle Fitment

• 2023+ Honda Civic Type R FL5
• 2024+ Acura Integra Type S DE5
• Left-hand-drive models
• Right-hand-drive models
• Applicable international-market models

Important: Designed for vehicles using the factory turbocharger inlet pipe only.

Performance-Oriented Intake Design

• Large 6-inch high-flow cone air filter
• Rotomolded HDPE enclosed air box
• Uses the factory front air duct and hood seal
• Additional secondary inlet helps reduce airflow restriction
• Stepped silicone connection with smooth transitions
• Designed to reduce intake heat soak during demanding driving
• More aggressive turbo and induction sound
• No ECU calibration required

Improved Air Supply

The factory rubber inlet extends over the radiator support and seals against the hood, directing outside air into the air box. PRL supplements this arrangement with an additional duct designed to address the restriction created by the original air inlet.

According to PRL’s product information, third-party testing identified a significant power reduction when the hood was closed, indicating restricted airflow through the factory duct. The secondary duct and larger opening were developed to improve air supply to the intake under real-world closed-hood operation. :contentReference[oaicite:1]{index=1}

Factory-Like Drivability

PRL designed the intake and MAF housing to maintain factory-like fuel trims and drivability while supporting higher airflow. No ECU calibration is required when the system is installed with the factory turbocharger inlet pipe. :contentReference[oaicite:2]{index=2}

Installation Notes

• Direct-fit intake system
• No ECU calibration required
• Fits the factory turbocharger inlet pipe only
• Verify compatibility before combining with an aftermarket turbo inlet pipe
• Professional installation is recommended when unfamiliar with intake-system installation
