I bought this to replace the cracked plastic plug (original) on a 2017 Jeep Renegade Trailhawk. It fit better than OJ’s glove!

This copper replacement plug was cleary the best choice. My vehicle had a plastic one from the factory.

I bright this because I snap the drain plug screw while flushing the coolant system after changing the water pump so I bought this screw and it does not fit at all it doesn't even twist down so if you have an LR4 or Land Rover in general do not buy this product.
