These oil pan drain valves replace your pan drain bolt and make chaning your oil easy and clean!

I bought the F106N version, which includes a nipple that you can connect a plastic tube to. This way, you can connect the tube, flip the valve lever, and drain the oil right into a container, no mess!
May want to consider a oil pan skid plate to protect the valve since it will be more suseptable to damage offroad.
