``High-performance sports filter designed based on intake theory!'' In order to revitalize the Hiace's gasoline engine, intake and exhaust tuning that is faithful to the basics is effective. Replacing with a sports filter has become a standard tuning practice these days, but in reality, it is often due to incorrect knowledge. The performance required of a naturally aspirated engine filter is dust suction ability and appropriate suction resistance. Although it is generally recognized that dust suction ability is necessary, it is not well known that suction resistance is important. Even when the throttle is open, air pulsates in the intake pipe due to the opening and closing of the intake valve. Unless the cam profile (working angle)* changes, the time the valve is closed increases in proportion to the increase in rotational speed, so the air-fuel mixture that was not drawn into the cylinder accumulates just before the valve, which increases the pressure. This causes a backflow phenomenon. If a filter with low suction resistance is installed, pulsation cannot be suppressed because there is no pressure difference between the inside of the intake pipe and the outside air, and the backflow of pressure forms a wall, reducing filling efficiency. A similar situation occurs near the throttle valve. Low-resistance type filters, which are designed based on the logic valid for supercharged engines (reduction of intake resistance = improvement of intake efficiency), have difficulty generating sufficient negative pressure in the suction, and are susceptible to throttle changes. In contrast, the amount of inhalation fluctuates dramatically. As a result, it becomes difficult to maintain a constant flow velocity in the intake air, resulting in poor response over a wide rotation range. “Hyper Flow Filter” is a genuine replacement type dry air filter developed with top priority on improving filling efficiency. By using a fiber filter with a special laminated structure, we have expanded the suction area to the limit while maintaining the optimal suction resistance based on tuning theory, ensuring a sufficient amount of air intake even at high rotations and high loads. The improved engine output, light response, and pleasant intake sound made possible by the Hiace's exclusive design guarantee an exceptional drive feel for everyone who operates it. *Some models are equipped with a "variable valve timing lift mechanism" that changes the cam profile at high speeds. (Honda VTEC, Mitsubishi MIVEC, etc.) Precautions for use ●Although this product complies with safety standards, please be aware that the inspector's judgment will take precedence when it comes to vehicle inspections. ●In addition to using a highly efficient special fiber filter, this product is designed to maximize the suction area. The intake noise will be increased compared to the genuine filter, but this is not a problem with the product itself.
