Original Equipment Manufacturer is the company that made the part(s) that were installed by the car maker at the factory. Due to federal and international guidelines for good business practices, there are normally two or more OEM brands for nearly every maintenance part on a vehicle. The use of an OEM part will ensure that you have a part made specifically to fit your vehicle.

Left = Driver side and Right = Passenger side.

All parts are priced individually unless identified as a set or kit. “Per car” notes identify how many of a given part your car has and
“Left/Right or Front/Rear” notes means the part fits the left or right side of the car. These parts are still sold individually and you’ll
need to select the appropriate quantity if you plan to replace more than one of this item.
