Genuine Hyundai Oil Pan Drain Plug Gasket, 21513-23001, Pack of 10
Drain plug gaskets may seem like an unnecessary expense, but they are inexpensive and serve a very important purpose. Drain plug gaskets not only ensure that the drain plug seals properly on the oil pan, but also makes sure that the drain plug isn't tightened so tight that it seizes, causing damage to both the drain plug and oil pan threads. They should be a part of every oil change.
