Racing Beat's extremely popular REVi RX8 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 and Duct Combo include: an OEM style air box assembly, custom-designed KandN air filter unit, aluminum mass air flow sensor tube, a tuned-length air inlet horn, and a nose-mounted intake air duct.

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 KandN 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!

Included with this combo kit is our Ram Air Duct which converts your intake into a true "cold air" system. The inlet of this duct is positioned in the mouth opening of the RX-8 and funnels cooler ambient air directly into the REVi Intake chamber. The REVi intake system addresses one of the most common complaints that we hear regarding aftermarket intakes for the RX-8 " extremely loud intake noise! Although a simple unshielded tube-and-filter intake system may produce respectable top end power, the noise levels that are produced are unbearably loud. During initial testing with one of more popular aftermarket units, Racing Beat recorded a full-throttle sound level reading of over 90 db inside the car, with the windows rolled up! Compared to the stock sound level, we believe that you will soon tire of this type of rocket-racer intake buzz. The REVi intake produces a much more modest intake sound with only a 2-3 db increase over the stock system. As described on by one of our prototype test volunteers, This intake is definitely louder than the factory unit, but not unreasonably so. It actually sounds deep and pretty darn good.

Notes: The original MAF sensor is retained for use with this intake, a replacement is not supplied with this kit. *Legal in California only for racing vehicles, which may never be used upon a highway.

After reading many other positive reviews on both the GWR and Miata forums I finally decided to buy this product. My main concern for many months was whether or not I was up to the task of installing the header. But with the excellent instructions on Brian's forum as well as several Miata forum threads it turned out easier than I expected. After receiving notice that the header would arrive on a Friday afternoon, I began the disassembly process. After about 3 hours I had the stock manifold out. Later that afternoon the new catted header arrived right on schedule. And it is a thing of beauty. I opted for the stainless version. Installation on Saturday morning took another 3 hours, although I could have shaved some time off of that but I was actually enjoying the process of double checking torque values and cleaning up my engine compartment. I already have the GWR catted midpipe, so that connection was a snap. I put everything back together, reconnected my battery, and went for a drive. NO CODES! Nice throaty sound with my RSII muffler, and a significant boost in power and low/mid torque. Another happy camper here. I since have added a M-E tune and I feel I have realized all of the gains that Brian has achieved on his 2012 project Miata. I've put several hundred miles on my Miata since the install with zero problems. This is the car that Mazda should have built all along. Thanks Brian.

Wanted to say thanks. The exhaust system fit perfectly, no drone at steady throttle, but a nice sound winding thru the gears. And it does sound a lot like my old Alfa. The Racing Beat lowering springs are just right. Appreciate the tech advice and the service.
