Ok, the plot thickens. Here is a photo of a 2009 engine cover:
And here is a 2012 cover.
Yet the part number at the dealer changed in late 2010 and get this, the price MORE THAN DOUBLED from the dealer. Does anyone know or care to guess if Toyota runs into a situation where they have to pay lots more for a part from their suppliers that they would change the part number to justify charging more than twice the amount for the part? Would they do that? Or might there be some change underneath that I'm not seeing, because to my eye, they look exactly the same.
And even if there was a change, what would cause the price to more than double?
