It’s best to have your original part number or the one listed on your current starter. This part number specifies the number of poles, the mounting type, and the power rating in kilowatts. This is important because there may be several different configurations for the same vehicle.
Depending on the brand—Valeo, SEG Automotive, Denso, or Mitsubishi—the specifications may also vary even for the same configuration.
