This is only the upper part of the fresh air guide for the Mazda DJ Demio. I am selling it because I am selling the vehicle. The following is quoted from the AutoExe website: Actively captures running air to improve intake efficiency. The "Fresh Air Guide" is an item that supports improved intake efficiency by directly capturing running air from the front of the vehicle. By directly connecting the front grille, where there is no clear intake path in mass-produced vehicles, to the air intake located on the upper part of the core support with a dedicated air guide, fresh air is introduced into the air cleaner box, minimizing the effects of heat exhaust from the radiator, etc., and improving filling efficiency. The product is installed inside the front bumper and is designed to be compatible with the mass-produced air cleaner box, Ram Air Intake System, and Sports Induction Box. It is compatible with mass-produced bumpers and AutoExe bumpers. This is a recommended item for users who are particular about intake efficiency. Retail price: 35,200 yen
