I bought a set of LS6 heads locally a while back and the guy threw in this SLP LS6 intake manifold. It’s an LS6 manifold that has been fitted with the EGR fitting that the 98-00 F-Body LS1s needed to pass emissions. I don’t have a use for it since I have an LS1 from a 2002 that does not require EGR. Part# 12573572
