What is an OE number?

An OE (original equipment) number is the part number assigned by the vehicle manufacturer to a component fitted on the production line. The same part is often sold under several aftermarket numbers, so an OE number is the most reliable way to find an exact replacement. Search a number to see every matching part in our catalog with prices, brands and vehicle fitment.
