How do I tell if I have a MY09 Pontiac G8?

"How do I tell if I have a MY09 Pontiac G8?" If you contact you local GM dealership they should be able to tell you based off the VIN. However generally if you engine as a single large engine cover, covering the intake manifold, it would be a MY09. Spit covers and it would be a MY08. To be sure though, best to contact your local GM dealership.
