The COBB Tuning MAF Block-Off Plate Kit is the perfect complement to Speed
Density tuning. Speed Density tuned vehicles use a Manifold Absolute
Pressure (MAP) sensor to monitor the mass of ingested air instead of the
OEM Mass Airflow (MAF) sensor, which means the MAF sensor can be
removed from the intake tube. 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 COBB Tuning 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
completey fills the MAF sensor opening and the face sits flush with the
inside of the MAF tube. This provides smooth, uninterrupted walls that
The COBB MAF Block-Off Plate is hard anodized in black for a durable,
corrosion resistant finish. The Block-Off Plate then go back on the CNC
mill for a final pass to have the COBB logo machined into the top face.
The kit is finished off with stainless steel button-head screws and
black nylon washers that gives the plate a professional appearance when
installed. The COBB MAF Block-Off Plate Kit works with the stock intake,
COBB SF Intake and any direct replacement intake with an inner diameter
similar to stock.
