Technical Notes:
Over time, PRL has established itself as the go-to place for Honda and Acura performance. Our engineers have dedicated substantial time to harnessing maximum power from this platform. We leave no stone unturned in our quest for performance, delivering top-notch and high-performing parts. With the introduction of the High Volume Intake System, we have raised the bar for Air Intake Systems for the FL5 and DE5 platforms.
Testing Data:
The development of the High Volume Intake System for the FL5 Civic Type-R and DE5 Acura Integra platform is complete. We applied lessons from our FK8 HVI and made significant improvements to the construction, materials, and overall design, resulting in an intake that rivals the best options on the market. Our FL5 Civic Type-R High Volume Intake system uses a 6" cone filter and an HDPE rotomolded air box. This air box utilizes the factory air duct and seal for optimal airflow and heat-soak reduction.
The factory rubber inlet connects to the box and extends over the core support. This rubber duct seals to the hood and channels air into the airbox via a duct in front of the radiator support. Experience with the FK8 emphasized the importance of keeping these cars cool during hard driving. Third-party testing revealed a 10-20hp loss with the hood closed, indicating that the factory duct is a point of restriction. In response, we developed the secondary duct to address this issue of air starvation.
With this integration, we maximized the opening size and eliminated restrictions associated with airflow into the box, resulting in a 133% increase in airflow over the OE unit. A more freely breathing engine produces more power. To maintain this free-breathing design throughout the entire intake system, we included our typical stepped silicone design, which matches each piece of silicone to each connection point. This ensures a smooth transition between all intake components and minimizes intake tract resistance.
As with all intakes produced by PRL, our primary objective is to provide a factory-like fuel trim for optimal drivability. We dedicated considerable time to designing what we believe to be the best intake system/MAF housing on the market. We are confident that our High Volume Intake System for the FL5 and DE5 platform will exceed your expectations, delivering the performance and quality synonymous with the name PRL.
