Unlock the Boxer Growl. Protect Your MAF Sensor.

The factory paper filter is a bottleneck. It’s designed for cost-efficiency, not flow. For the Impreza and Forester Turbo platforms, the Fuji Racing High-Flow Filter is the definitive "Drop-In" upgrade. Engineered from multi-layer woven cotton, this filter provides a significant increase in surface area and airflow while maintaining the superior filtration required for a reliable daily or track build.

Whether you're running a stock setup or a mildly modified EJ20/EJ25, this is the fastest way to sharpen your throttle response and hear your turbo breathe.

The Roo Racing Difference:

• ✅ Direct OEM Fitment: Drops straight into your factory airbox in minutes. No cutting, no zip-ties, no "custom" fabrication.

• ✅ MAF-Safe Engineering: We recommend running this filter dry (un-oiled) for cars still utilizing the Airflow Sensor (MAF) to prevent sensor contamination and "ghost" idling issues.

• ✅ Sustainable Performance: Fully washable and reusable. This is the last air filter your Subaru will ever need.

• ✅ Superior Filtration: High-density woven cotton captures particulates that "cheap" mesh filters miss.

Technical Specifications:

• Material: Multi-layer woven cotton for maximum CFM (Cubic Feet per Minute) flow.

• Maintenance: Washable with standard filter cleaner.

• Installation: 5-minute "Drop-In" replacement for the standard panel filter.

Confirmed Fitment:

Designed specifically for the "Golden Era" of Subaru Turbo platforms:

• Subaru Impreza Turbo / WRX / STi: 1992 – 2007 (GC, GD, GG Chassis)

• Subaru Forester Turbo / GT / XT: 1996 – 2008 (SF, SG Chassis)

Specialist Note:

If you are still running a factory Air Flow Meter (MAF), avoid using oil additives after washing. Running the filter "dry" ensures your sensor stays clean, keeping your AFRs (Air-Fuel Ratios) stable and your engine healthy.

Stop suffocating your turbo. Let it breathe with Fuji Racing.
