Review on 🔧 Genuine Hyundai Oil Pan Drain Plug Gasket 21513-23001 - Pack of 5 - Enhancing SEO by Michael Lucas

That's exactly what they say and if you have a Kia/Hyundai and change the oil yourself you should always change it after you drain it. On the other hand, it would be nice if Kia/Hyundai just included it in the filter, but it's nice to have them on hand. Sometimes you're lucky and the retailer gives you a filter for free, but the filters there have a premium, so it's cheaper to buy it here.
