MAF Block Off Plate

• 2004-2008 Subaru | Forester XT
• 2002–2014 Subaru | WRX
• 2004–2021 Subaru | WRX STI

The GrimmSpeed MAF Block Off Plate (053001 / 053002) blocks off the original MAF sensor location when a Subaru is upgraded to a blow-through system. The compact plate features black anodized aluminum for a clean finish, and the bottom of the plug is contoured to the diameter of the intake piping so the plug is not in the way of flow.

• Black anodized aluminum plate
• Durable O-ring for a perfect air-tight seal
• Plate is curved to fit the piping, with no intrusions into the flow path
• Easy to install in under 2 minutes
• Two versions: 053001 for 2002-2007 WRX/WRX STI and 2004-2008 Forester XT; 053002 for 2008-2014 WRX and 2008-2021 WRX STI
• Part numbers: 053001, 053002
