Holding the 2 gaskets side by side it took me a while but there is a visual difference, there are some ribs added to the new unit that are not present on the old one. Digital calipers did not pick up any difference on thickness.

The valve covers and the brass dowels appear to be identical.

The added ribs look like they will help, they are spaced between the bolt holes every inch or so. they look like they will act like a wedge to keep the gasket from compressing up into the grove on the cover.

So, if your 09 leaks, just get the gasket and bring your old one with you to compare.You CAN buy just the gasket, my dealer got me one not knowing it was included in the cover assembly.
