Vibrant MAF Sensor Adapter Plate for 2002-2007 Subaru Impreza WRX STI use w/ 3in Inlet I.D. filters only
Vibrant Performance mass air flow sensor adapters connect aftermarket 3-inch inlet cone style air filters directly to the MAF sensor in Subaru intake systems. This adapter plate fits 2002-2007 Impreza WRX and STI models equipped with Hitachi oval MAF sensors. It delivers precise alignment and secure mounting for unrestricted airflow and reliable sensor readings during performance driving.
Key Features
- T6061 Aluminum Construction: Lightweight yet durable material resists corrosion and withstands high-heat engine bay conditions for long-term reliability.
- CNC Machined Precision: Exact tolerances ensure seamless fit between cone filter and MAF sensor without airflow restrictions or sensor misalignment.
- 3-Inch Inlet Compatibility: Designed exclusively for filters with 3-inch inner diameter to maintain optimal air velocity and volume into the MAF.
- Subaru-Specific Design: Matches the oval Hitachi MAF housing on WRX and STI models for bolt-on installation without modifications.
- Anodized Finish: Hard anodized coating provides scratch resistance and reduces wear from vibration and debris exposure.
Product Notes
- Compatible only with 3-inch inlet ID cone filters. larger or smaller filters require different adapters.
- Inspect MAF sensor O-ring during install and replace if damaged for accurate readings.
- Compact design ships flat in protective foam sleeve to prevent bending.
Installation Notes
- Professional installation recommended.
- Remove stock airbox and MAF housing. adapter bolts in place using existing hardware.
- No additional clamps needed. uses stock MAF gasket and M6 bolts for secure mounting.
