Features:
The GrimmSpeed MAF Block Off Plate allows you to block the location where the old MAF Sensor was when upgrading your Subaru to a Blow-Through System. This compact design features black anodized aluminum for a clean finish. At GrimmSpeed, they have taken it one step further and contoured the bottom of the plug to the diameter of the intake piping so the plug is not in the way of flow!
Anodized black finish with white GrimmSpeed logo
Durable aluminum construction
Includes O-ring for a perfect air tight seal
Designed to block the factory MAF provision when converting to speed density
Compact, clean, and logical design - the plate is curved to fit piping for no intrusions into the flow path
Easy install
