THIS IS METAL! I can confirm that this will fit a 2014 Rav 4 with a 2.5 liter four cylinder engine. This fixed a leak (minimal thread crack) on the cheap factory plastic. It's also much easier to screw in than plastic. Received in three days with regular free shipping. There are too many bad reviews about aftermarket metal replacements, which is why a Toyota OEM part is only a few dollars more.
