BMW has been known to use cheap plastic radiator drain plugs in their cars. Over time the heating and cooling of the radiator causes the plastic drain plug to crack or strip.  To solve this issue, we created a brass alternative.  Completely plug and play to the original plug, these upgraded plugs will last a lifetime, and not strip. We have also added a safety wire hole for extra security if you choose.
