MAF Block Off Delete Plate

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.

We start with billet 6061 T6 aluminum and CNC-machine a plate/plug to seal off the opening left when the MAF sensor is removed. The plug has two unique features that are key to reliable performance. The first is an O-ring that tightly seals the Block-Off Plate to the MAF sensor opening, preventing unfiltered air from entering the intake tract. The second feature is the shape of the plug face, which is sculpted to exactly match the inside curve of the MAF tube. When seated, the plug completely fills the MAF sensor opening and the face sits flush with the inside of the MAF tube. This provides smooth, uninterrupted walls that prevent turbulence.
