Blockoff / lock / flange for speed sensor hole EFR / AirWerks / G25 / G30 incl. mounting material Block Off Speed Sensor Kit for EFR / AirWerks / G25 / G30 Blockoff flange for speedsensor port of EFR / AirWerks SX-E / Garrett G25 / G30 To block off the speed sensor port of the BW EFR / AirWerks SX-E / Garrett G25 / G30 compressor housings Block Off Flange for BorgWarner EFR / AirWerks SX-E / Garrett G25 / G30 compressor housings, to replace and close the port in the compressor housing for the EFR speed sensor. The flange comes as kit incl. O-ring and mounting screw. One or the other may not always want the speed sensor mounted on the BorgWarner EFR / AirWerks SX-E / Garrett G25-550 / G25-660 / G30-660 / G30-770 compressor housings. For this we have produced a sealing flange that fits perfectly into the original port. Our flange is made of a special polymer (much more stable and heat resistant than other plastic versions), the sealing ring is heat resistant up to 200°C and therefore completely sufficient for the compressor housing. The shown compressor housing is not part of the scope of delivery, but serves only for a better illustration of the Block Off flange!
