The Speedmaster line of manifolds for LSX type engines was designed to provide extra plenum area which is very advantageous on larger displacement versions of the LS1/ LS6 and LS2 engines. If you have a punched out LS engine the stock manifold will not be able to do the job. Additionally if you are running a supercharger or turbocharger a plastic manifold will not survive a backfire so our aluminum Elite is your answer.  These Manifold is a direct replacement for any LS1 or LS6 intake but has provision for the larger LS2 style throttle body. It also has a 96mm inlet that can be opened up to 101mm.
