TPI intake question

I have a 91 L98 with the dealer installed SLP kit and have a question about the intake manifold. Is the factory manifold aluminum or steel on a 91 L98? Mine is aluminum and I am wondering if it is original or not. The reason I ask is because I dont think that the intake was part of the SLP kit. Thanks.

The stock manifold is aluminum, and was not part of the SLP kit.

Dealer installed SLP kit? Only one I've ever heard of was the T-RAM on the Firehawk.
Stock intakes were aluminum however.
