HKS Super Hybrid Drop-In Air Filter for the Scion FR-S / Subaru BRZ are direct replacement panel filters designed to fit into the standard factory air box. Using a 3 layer dry filter, the super hybrid filter separates and catches dust particles within the air and optimises air flow direction through the filter.
The new 3 layer filter system catches larger dust particles with the first layer and smaller particles are filtered out by the 2nd polyurethane layer. This has allowed increased filter life over previous models. Improvements were also made to the way the layers are attached to each other allowing for improved air flow.
