/Rotary Extreme Cold Air Intake for RX-8/
(6-11-2010): We are in the process of making a new version of the cold air intake for the RX-8. The current version is already discontinued.
The standard short arm intake kit comes with
air filter
3.5" intake pipe with CNC-machined air flow sensor adapter
heat shield
polished top cover
| Our Intake kit comes with polished aluminum top cover to minimize hot air getting into the engine. Colder air makes more horsepower. | Another angle of the fully polished top aluminum cover. | The filter is a reusable and washable cotton element type. | Our CNC- machined air flow sensor adapter is TIG welded onto the 3.5" intake piping. | CNC-machined air flow sensor adapter is CNC-machined to make sure the sensor is at the center of the piping. |

Before you Order: We have found that a minority of RX-8's do not like a higher flow intake. Even though all RX-8's are supposed to be the same from the factory but unfortunately, they are not. This has to do with the version of the ECU program and also the batch of the MAF sensor. To ensure that our intake system will work on your RX-8, please do a simple test by removing the stock air filter from the stock air box and run your car from 1st to 3rd gear in full throttle and see if there is any kind of hesitation. Without the stock air filter in place, the stock intake system simulates a higher flow intake. If there is hesitation, any aftermarket high flow intake system will not work on your car, including ours. If there is not any hesitation and the car accelerates smoothly, you will see the promised HP gain from our intake system.
HP Rating: We have found that the 238 HP version RX-8 stock HP rating varies from 168 rwhp to 187 rwhp. Mazda has reflashed the ECU several times and the HP rating variance has something to do with the ECU program. We have found the first batch of RX-8 produced the most HP on the dyno. The recent batches have on average of 170 rwhp. Regardless of the base HP, the intake produces almost the same kind of HP gain at 8-12 rwhp at high rpm.
More Info on Dyno Testing: Our intake has been tested on many cars to ensure the result is repeatedly. If you want to know more on how we dyno test the intake, please go to the following link:
