Is it only PI manifolds that are equipped with the aluminum crossover? I was under the impression that some NPI manifolds had the aluminum crossover as well, making it hard to determine which is which.

I have a NPI intake on my 98 that has the aluminum crossover. You need to look at the ports and the depth of the runners.
