Fuji Racing High-Flow Performance Air Filter (Direct OEM Replacement)

Breathe Better. Run Reliable. The Ultimate "Drop-In" Upgrade.

The factory paper filter is a bottleneck designed for the average commuter, not the Subaru enthusiast. For the modern Forester, Impreza, and Liberty platforms, the Fuji Racing High-Flow Filter is the definitive "OEM Plus" upgrade. Engineered from multi-layer woven cotton, this filter provides a significant increase in surface area and airflow, sharpening throttle response and improving induction efficiency without the need for a noisy, heat-soaking pod filter.

The Roo Racing Difference:

• ✅ Direct Fitment: Drops straight into your factory airbox in minutes. No modifications, no tuning required for standard or mildly modified cars.

• ✅ MAF-Safe Engineering: We recommend running this filter dry (un-oiled) for vehicles utilizing a Mass Air Flow (MAF) sensor to prevent sensor contamination and idling issues.

• ✅ Washable & Reusable: This is a lifetime component. Simply wash, dry, and reinstall—reducing waste and long-term maintenance costs.

• ✅ High-Density Filtration: Woven cotton captured particulates that inferior "mesh" filters miss, protecting your turbo and internals.

Confirmed Fitment:

This high-flow panel filter is a precision fit for a wide range of modern Subaru chassis:

• Subaru WRX & STi: GE, GH, GR, GV (2008–2014)

• Subaru Impreza: GE, GH, GR, GV (2007–2011)

• Subaru Forester: SH & SJ (2008–2018)

• Subaru Liberty & Outback: BL, BP, BM, BR, BN, BS (2003–2020)

• Subaru XV: GP (2012–2017)

Specialist Note:

If your Subaru is still running the factory Air Flow Meter (MAF), we strongly advise against using oil additives after washing. Running the filter "dry" ensures your sensor stays clean, keeping your Air-Fuel Ratios (AFRs) stable and your engine healthy for the long haul.

Stop suffocating your engine. Let your Boxer breathe with Fuji Racing.
