When you upgrade your Subaru to a Blow Through System you will need a way to block off the location where the old MAF Sensor was located. Now GrimmSpeed has the answer with the GrimmSpeed MAF Block-Off Plate which allows you to black off the factory MAF provision. This compact design features black anodized aluminum for a very clean finish. Grimmspeed has taken it one step further and matched the bottom of the plug to the diameter of the Subaru intake piping so the plug is not in the way of flow.
Installation of this component is considered to be simple and can be done in a few minutes. An O-ring will be supplied to provide a perfect airtight seal, and hardware will also be provided to make this MAF Block-Off Plate ready for the installation.
