Product character	A basic item that utilizes the mass-produced air filter box and replaces only the filter part.	Utilizing a part of the mass-produced air filter box, you can enjoy the improvement of intake efficiency and sports sound.	It consists of a carbon box and a filter with a specially designed intake path.A high-end model that pursues efficiency and looks.	Intake pipe that reduces intake resistance and enhances efficiency by suppressing internal unevenness and deformation.	Adult texture with a sophisticated oval tail.The aim is to improve exhaust efficiency and a comfortable sports sound.	Special specifications that give a feeling of bold performance.Exhaust efficiency top priority design.Install at the same time as a dedicated garnish.
Change in riding taste (Commitment)	By improving the intake efficiency, the accelerator feels better and the engine blows up lightly.Since a mass-produced cleaner box is used, the change in intake sound is minimal.	By actively taking in air, it responds quickly to accelerator work.Releases the intake sound suppressed by the mass-produced muffling resonator and box.	By introducing fresh air from the air duct from beginning to end, you can enjoy a torqueful acceleration feeling as the speed range increases.	Efficiently guides the air and improves the feeling of fluttering at the beginning of stepping on the accelerator.However, there is little change in the sound aspect. (The sound of RX-8 changes due to the elimination of the muffling resonator)	Specifications that you can enjoy the torque feeling and the sound with restraint synchronized with the accelerator from the normal range to high rotation.The idling is quiet and the fit is casual.	A feeling of acceleration from the middle rpm range to the high rpm.The power of appearance that is clearly different from mass production is also attractive.
Technical features (Notice)	Uses dry non-woven fabric that has little effect on the airflow sensor.A disposable type that balances ventilation and dust collection effect for easy maintenance.	Specifications that combine the versatility and maintainability of mass-produced air filters.The muffling resonator and the suction side case are released, and equipped with a rectifying funnel.	Increase the amount of intake air within the margin of mass-produced ECU to promote fuel injection.The idea of ​​taking in air with ram pressure using an air filter and intake duct that emphasize efficiency.	The bellows-shaped flexible joint is eliminated to suppress turbulence of intake air.Secure the maximum effective flow path area.Polystar silicon and FRP materials suppress deformation due to negative pressure.	The exhaust efficiency has been improved by changing from the multi-stage expansion type of mass-produced vehicles to a straight structure.By appropriately reducing the diameter of the main pipe and punching pipe, torque reduction in the low speed range is suppressed.	The exhaust efficiency has been improved by changing from the multi-stage expansion type of mass-produced vehicles to a completely straight structure.A clear sports sound with a unique sound deadening structure that does not use glass wool.
