ABN Oxygen Sensor Offset Puller 3/8 Inch Drive 7/8 Inch Socket
Does what it says on the tin.
Built right, fits well, and makes short work of the job. If I ever need another one, I'll order this again.
Bosch O2 Oxygen Sensor New for Subaru Impreza Forester 1999-2003 13469
Excellent replacement part.
Bought as a "used" part, however the part looks brand new. The only thing setting it apart from a new unit was the anti-sieze compound that had been applied to the threads. Added value not having to spread any more on it before installation!
