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 LS2 intake. It has a 96mm inlet but can be enlarged to accept a 101mm throttle body.
- Excellent throttle response throughout the RPM range along with smooth engine operation
