If 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. The GrimmSpeed MAF Block Off Plate allows you to do just that! This compact design features black anodized aluminum for a very clean finish. We 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!


  • Easy to Install, under 2 minutes.
  • Durable o-ring for a perfect air tight seal.
  • Compact, clean, and proudly displaying the GrimmSpeed Logo.
  • Logical Design. Plate is curved to fit piping for no intrusions into the flow path.

missing screws and washers

Grimmspeed's site shows screws and washers...I didn't receive any.


We appreciate your review of the GrimmSpeed MAF Block Off Plate. Unfortunately GrimmSpeed does not offer the screws with their block off plate and OEM hardware should be reused. I do apologize for the confusion.
