_______
The development of the High Volume Intake System for the FL5 Civic Type-R and DE5 Acura Integra platform is complete. We have applied what we learned 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 uses 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. Our experience with the FK8 taught us the importance of keeping these cars cool during hard driving. Third-party testing revealed a 10-20hp loss when the hood is 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 to be as large as possible, along with the secondary duct eliminating any restrictions associated with airflow into the box. As a result, there is a 133% increase in airflow over the OE unit. It is no secret that a more freely breathing engine produces more power. In order to maintain this free-breathing design throughout the entire intake system, we have also 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 that has become synonymous with the name PRL.

Best intake for fl5
Thanks again to Humza for delivering this product at a nice deal and quickly over the Thanksgiving holiday. I think this is the best bang for buck HVI considering it's a mostly closed box, guaranteed whoosh sounds, and HP increase comparable to much more expensive intakes. I completed the install with hand tools although it was somewhat tricky as this was first intake I ever installed and mind you I did not install the secondary duct that it comes with because that required removing the ECU, which I deemed was not worth the squeeze considering the tools I had. An extended torque wrench for the 10mm bolts down low would have made things a lot easier, but I managed and am very happy with the intake. The whoosh sound and quicker rev is great. Note, my car acted up the first start up and drive around the block (limp mode, lights, etc.) however, after turning off and back on a second time, everything went back to normal. Car sounds awesome now as the turbo spools !
I got this and the PRL Titanium Turbocharger Inlet Pipe Kit for my ITS and let me tell you this intake is not just about sound!!
Not only it is loud and satisfying to listen to, but also the difference it made in my throttle response is night and day.
The throttle response in all modes (comfort, sport and sport+) is way better now and the car did really wake up.
