BorgWarner EFR Turbo Speed Sensor Kit

This kit is to be used exclusively in conjunction with BorgWarner EFR turbo line. Being able to properly measure turbo speed (how fast your turbo is spinning) is crucial in determining your engine's peak operating range. Traditionally, turbo speed sensor installations were extremely difficult for the end user, requiring arduous machine work. Fortunately, the EFR lineup is already setup to accept their own speed sensor, all that is required is to drill a 1/4" hole in their predetermined location, and you've got your monitoring location.
