Are you worried that you may have been running the wrong filter? When I plug that filter part number (pl14459) into the purolator web site, it says that filter fits your car.
Also, when I use the application guide at the purolator web site, it says that is the correct filter for your engine, and that the 14612 is only for the 4 cylinder legacy engines
When I go to the advance auto parts website and search your car, it does in fact say the 14612 oil filter. I wouldn't worry about that though, I would trust what the purolator web site says, which is that the 14459 is the correct filter.
