Speedmaster 1-148-014 EFI 102mm 4 Bolt Intake Manifold Satin for Chevy/GMC

Chevy GM LS1 LS2 LS6 EFI 102mm 4 Bolt Intake Manifold Satin 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. It has an 102MM inlet. Excellent throttle response throughout the RPM range along with smooth engine operation
