Product Description

The GrimmSpeed GRM060091 Dry-Con panel filter offers Subaru owners a straightforward, no-tune-required way to pick up real power without committing to a full aftermarket intake system. Designed as a direct drop-in replacement for the factory airbox, it delivers 62% better airflow than the OEM filter while maintaining the same level of particulate filtration to keep the turbocharged engine protected.

Its oil-free Dry-Con element construction improves long-term reliability and simplifies maintenance compared to traditional oiled performance filters, which can risk contaminating mass airflow sensors if over-oiled. Dyno-tested to add up to 9 lb-ft of torque and 6 whp, this filter is a safe, simple upgrade for WRX, STI, Forester, Crosstrek, and Legacy/Outback turbo owners wanting a quick, reliable performance boost backed by a lifetime warranty.
