The BorgWarner EFR low-boost actuator is specified for use with 55mm and 58mm TW configurations and listed alongside 0.92 TH housings, providing a compact boost-control option for compatible EFR turbo setups. It supplies consistent wastegate actuation where lower boost calibration is required and helps tuners match actuator force to specific turbine and housing combinations.
