MAF Block-Off Plate - Subaru 02-07 WRX/STI

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.

GrimmSpeed was founded in 2006 to provide customers with innovative and highly engineered aftermarket products. On a more personal level, we are a group of car enthusiasts in the lovely city of Minneapolis, Minnesota who are absolutely passionate about what we do. Our bread and butter started out anything Subaru. However, after growing our team and engineering expertise, we started developing products for Mitsubishi, Ford, MazdaSpeed, and Hyundai markets. We are a true garage start-up (single stall townhouse garage in Maplewood, MN) and we've been lucky enough over the years to be able to turn it into exactly the business we had dreamed of....actually, much more. We have a wide breadth of product offerings including: intercoolers, exhausts, intakes, gaskets, engine pulleys, phenolic spacers, boost controllers, and many more.
