HKS Lexus SC430 Super Air Filter 70017-AT115

Long-term Low Resistance - Even after long-term use of the filter, the intake resistance stays as low as new. Filter Specifications - Monolayer Polyester Non-woven Fabric (Density Gradient Structure) Filter Structure Comparison - A pleated type sports filter usually collects various sizes of dust on its surface; therefore, air passage becomes narrower which easily causes filter clogging even initial ventilation resistance is low. - HKS Super Air Filter utilizes the density gradient structure where filter density becomes higher with each layer ensures all sizes of dust and other particles are caught gradually which maintains proper air passage resulting in a long product life.
