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, well GrimmSpeed™ has the answer. GrimmSpeed™ MAF Block Off Plate allows you to do just that! Compact design that features black anodized aluminum for a very clean finish. We have 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!!
- Easy to Install. Under 2 minutes for installation.
- 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.
