OES - Original Equipment Supplier (dealer Parts)
OES stands for Original Equipment Supplier. This refers to the part that is provided to us by the actual vehicle manufacturer. So when you see a part that has OES in the description, or we refer to a part as OES this part actually came from the vehicle manufacturer and in most cases will come in the vehicle manufacturers packaging and is the genuine product. On our web site we are not allowed to indicate the item as “genuine”, so for the items that are genuine factory parts you may see the item listed as OES or in some cases you may see OE Service. So if there is any confusion as to whether an item listed on our site is genuine, please call our customer support staff as they can determine if the item is in fact genuine. These parts are in fact the same part you would get at the local dealer.
