The Typhoon manifold 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 Typhoon is your answer. Note that all of our LSX manifolds come complete with the fuel rail kit as shown in the photos. |
