Product character	By utilizing mass-produced air filter boxes, A basic item where only the filter part is replaced.	By utilizing a portion of the mass-produced air filter box, Enjoy improved intake efficiency and a sporty sound.	The intake path consists of a specially designed carbon box and filter. A high-end model that pursues efficiency and looks.	By suppressing internal irregularities and deformation, An intake pipe that reduces intake resistance and improves efficiency.	The sophisticated oval tail gives it a mature feel. The goal is to improve exhaust efficiency and produce a pleasant, sporty sound.	Special specifications that give a feeling of bold performance. Designed with exhaust efficiency as the top priority. To be installed in conjunction with dedicated garnishes, etc.	The look is subtle, yet high quality. A special edition product for FD & NA, discontinued sports cars.
Change in riding taste (Commitment)	The improved intake efficiency resulted in better throttle response. The engine revs up smoothly. Because a mass-produced cleaner box is used, the change in intake noise is minimal.	By actively taking in air, the system responds quickly to accelerator input. The mass-produced sound-dampening resonator and box release the intake sound that has been suppressed.	By continuously introducing fresh air through the air duct, The higher the speed, the more torquey and responsive the acceleration feels.	It efficiently directs airflow, improving the sluggish feeling when initially pressing the accelerator. However, there are few changes in terms of sound. (The RX-8's sound changes due to the removal of the sound-dampening resonator.)	From the normal operating range to high RPMs, the torque feels synchronized with the accelerator. Designed to deliver a restrained and enjoyable sound. It idles quietly and feels discreet when installed.	The exhilarating acceleration from the mid-range to the high-range RPMs. Its striking appearance, clearly different from mass-produced items, is also a major draw.	From the normal operating range to high RPMs, the torque feels synchronized with the accelerator. Designed to deliver a restrained and enjoyable sound. It idles quietly and feels discreet when installed.
Technical features (Notice)	A dry nonwoven fabric is used, which has minimal impact on the airflow sensor. A disposable type that balances ventilation and dust collection effectiveness. Maintenance is also easy.	This specification combines the versatility and maintainability of mass-produced air filters. The sound-dampening resonator and intake side case are opened, and a rectifying funnel is installed.	Increase the intake air volume within the margin of the mass-produced ECU to promote fuel injection. Thanks to the efficiency-focused air filter and intake duct The idea is to draw in air using ram pressure.	By eliminating the bellows-shaped flexible joint, Suppresses turbulence in the intake air. Maximizes the effective flow path area. Polyester silicone and FRP materials suppress deformation caused by negative pressure.	The exhaust system was changed from a multi-stage expansion type to a straight-through design, improving exhaust efficiency. By appropriately narrowing the diameter of the main pipe and the perforated pipe It suppresses torque reduction at low speeds.	The exhaust system was changed from a multi-stage expansion type used in mass-produced vehicles to a completely straight structure to improve exhaust efficiency. A crystal-clear sports sound thanks to a unique sound-dampening structure that does not use glass wool.	The exhaust system was changed from a multi-stage expansion type to a straight-through design, improving exhaust efficiency. By appropriately narrowing the diameter of the main pipe and the perforated pipe It suppresses torque reduction at low speeds.
