New stock replacement air filter made from a new innovative dry non-woven fabric filter. On a high level, high dust collection capacity and low resistance are implemented combined. The density gradient structure, in which filter density increases with each layer, ensures that all sizes of dust and other particles are captured as effectively as possible. The ventilation resistance is reduced by optimizing the fiber components. Despite the lower intake resistance, the dust collection capacity is greater than the previous generation. (Collected more than 95% of the dust volume during in-house testing) Capturing dust consistently to supply clean air to the engine. A pleated type sports filter typically gathers various sizes of dust on its surface; as a result, the air channel grows narrower, resulting in filter blockage even when the initial ventilation resistance is modest. HKS Super Air Filter employs a density gradient structure in which filter density increases with each layer to ensure that all sizes of dust and other particles are collected progressively, resulting in the proper air passage and long product life.
