The IAG Performance MAF Sensor Block Off Plate for the 2008+ Subaru WRX, 2008-21 STI & 2005-09 LGT is designed to seal the MAF sensor location on cars that are converted to speed density tuning (where the MAF sensor is no longer needed). The block off plate can be used in a wide range of aftermarket intake applications utilizing a stock-style MAF flange. The IAG block off plate is engineered and manufactured in our own facility in Westminster, Maryland. The product is machined from 6061 billet aluminum, then anodized clear to add a protective finish. Each plate features our laser engraved piston logo on the top. The IAG MAF Sensor block off plate includes a new o-ring for easy installation.
