The Fuji Racing MAF Block-Off Plate is the perfect complement to Speed Density. Speed Density tuned vehicles use a Manifold Absolute Pressure (MAP) sensor to monitor the mass of air instead of the Airflow Meter (MAF) sensor, which means the MAF sensor can be removed from the intake.
Removing the MAF sensor eliminates a point of restriction and turbulence in the intake tract, but can present additional issues if not done properly. The Fuji Racing MAF Block-Off Plate is the easiest way to safely delete the MAF sensor for optimal performance and enhanced engine bay appearance.
Suitable for the following models:
Subaru Impreza 2000 – 2007
Subaru Forester 2002 – 2008
Subaru Legacy Twin Turbo 2000 – 2003
Subaru Legacy 2003 – 2009
