Description
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 LS2 or LS6 intake.
