Last year i installed a used engine in my 96 pontiac bonneville in which came from a 2003 grand prix i was doing some comparison and i notice that the lower intake on my old engine looks different than the one on my new engine... could this be that the lower intake was change?? help??

How does it look different?

The upper intake manifold (top most middle part) changed from plastic to aluminum in 04, I thought. Other than that, I can't think of anything...

Aluminum vs. plastic gaskets, perhaps? Or is 03 too early? Well, it's "old" GM, anything's possible...
