The 2011+ Subaru STI HKS Super Hybrid Drop-In Air Filter is designed to increase horsepower and acceleration while providing excellent filtration. HKS' high-performance Super Filters are a direct replacement for OE panel filters when a factory airbox is required or preferred. Super Filters feature the same 2-layer wet-type, polyurethane material as in the Super Mega Flow. The filter element is bonded to a flexible nylon frame and offers a price-friendly performance alternative to a full intake system.
