HKS Super air filter Subaru Type 1 (WRX/ STI 2008- 2018)
HKS Super Air filter
New stock replacement type air filter utilizing newly developed dry non-woven fabric filter. High dust collection capacity and low resistance are implemented together at a high level.
Newly Developed Dry Non-woven Fabric Filter
The density gradient structure where filter density becomes higher with each layer ensures all sizes of dust and other particles are caught in the most effective way. Optimizing the fiber components reduces the ventilation resistance.
Low Resistance & High Dust Collection Capacity
Even though the intake resistance is reduced, the dust collection capacity is higher than previous model. (Collected more than 95% dust volume during in-house testing) Reliably capturing dust to provide clean air to the engine.
Long-term Low Resistance
Even after long-term use of the filter, the intake resistance stays as low as new.
