Selling 2010-2015 Prius Engine Head Cover: $50 No damage, just dirty. Public meet-up in Central Valley/Bay Area, California
I thought at first it was the valve cover for sale but yeah this is the plastic trim personally if that's missing off one of my generation threes it can stay off.
Yeah I am not to worried about it either did not want to just throw it out if someone else might want it. Had to make room for the oil catch can.
