VQ35HR/VQ37HR Engines
Hey guys,
I'm reading through this owner's manual and I'm noticing it keeps referencing a VQ35HR engine and a VQ37HR engine. Biggest differences I seem to find is that they use different spark plugs, and the VQ35 recommends 91 octane fuel while the VQ37 absolutely needs 91 octane.
How do I know which of these engines I've got? Is it as simple as G35s have the VQ35 and G37s have the VQ37? Or is it something else? I'm using premium fuel, so I'm not really worried about it...just thought it'd be something worth knowing.
EDIT: Sorry if this is covered somewhere. I searched through a few different forums and couldn't find anything.

The VQ37 currently on the coupes do not make into the sedans until the 09 model year.
