Many automobile manufacturers offer an extended warranty on their vehicles.Typically, in order for the warranty to remain valid, the manufacturer requires that any replacement parts the consumer purchases for their vehicle be OEM parts (parts produced by the original automobile manufacturer).If a consumer purchases and uses replacement parts produced by any other supplier, the warranty will be declared void and canceled.
