Doing an oil change on your Toyota 4Runner or similar model? Don't reuse the old crush washer on the drain plug - it's a recipe for leaks. This is a pack of 5 brand new replacement gaskets. They're made from aluminum alloy (the classic blue color you often see), with an inner diameter of 12mm (M12), outer diameter of 21mm, and 2mm thick. They're designed to match the OEM Toyota part number 90430-12031. Just swap out the old, flattened one for a fresh, soft one before you screw the drain plug back in. It crushes slightly to create a perfect, leak-proof seal between the plug and your oil pan. Super cheap insurance against drips and oil stains on your driveway. Comes as a 5-pack, so you've got spares for future oil changes. An essential little part for any DIY mechanic.
