Description Racing Beat offers their extremely popular REVi Intake System for all RX-8 applications. Designed to offer performance improvements without sacrificing drivability, the Racing Beat intake system is the final result of hundreds of hours of dyno test sessions and on-road testing. The major components of the REVi Intake System include: an OEM style air box assembly, custom-designed K&N air filter unit, aluminum mass air flow sensor tube, and a tuned-length air inlet horn. Unlike many of the aftermarket intake systems on the market, the Racing Beat intake system retains one of the important mesh screens to aid with the even distribution of airflow across the mass air sensor. The inclusion of this screen minimizes the possibility of “rough idle” issues that may occur if both stock screens are eliminated. Working with the design team at K&N Engineering, a high capacity air filter was developed that allowed us to position a tuned-length intake horn inside the filter body. This filter design allowed us to fine-tune the length of the air horn to maximize the performance potential. We have noted that many aftermarket intake systems for the RX-8 incorporate a large air filter, which is then connected to the intake manifold with a length of plastic or metal tubing. In many cases, the size of the filter that has been selected will dictate the length of tubing required, severely limiting the critical tuning importance of the air intake tube! Notes: The original MAF sensor is retained for use with this intake, a replacement is not supplied with this kit.
