Genuine replacement type Tuning parts that can be easily installed by simply replacing the genuine filter.・Using a newly developed dry non-woven filter density gradient structure, the filter density is gradually changed from a coarse layer to a fine layer in response to air flow, ensuring that dust of various sizes is removed in stages. to be captured. Additionally, by optimizing the fiber composition, we were able to reduce the resistance throughout the year.・Both low resistance and excellent dust collection performance Despite reducing intake resistance, the dust collection performance is equal to or better than our conventional model (captured over 95% of the standard dust in our tests). Reliably captures dust and supplies clean air to the engine.・Keeps low resistance over a long period Not only is the resistance low when new, but it also maintains that resistance over a long period of time.

[Newly developed dry non-woven fabric filter] Adopts a density gradient structure that gradually changes the filter density from a coarse layer to a fine layer in response to air flow, allowing dust of various sizes to be removed in stages. definitely capture it. Additionally, by optimizing the fiber composition, we were able to reduce the resistance throughout the year. Despite reducing intake resistance, the dust collection performance is equal to or better than our previous model (captured over 95% of standard dust in our tests). Reliably captures dust and supplies clean air to the engine. Not only does it have a low resistance value when new, but it also maintains a low resistance value over a long period of time. A typical pleated sports filter captures everything from large particles to fine particles on the surface. As a result, the air passage becomes narrower, and even if the initial ventilation resistance is low, the period until clogging occurs becomes shorter.However, the HKS Super Air Filter uses density gradient non-woven fabric, which gradually improves the filter's openings. Gradually captures large pieces of garbage by breaking it down into smaller pieces. Air passages can be secured, resulting in excellent long-life performance.
