JM Fabrications “Race Version” Intake Manifold | 1990-1994 1G DSM (1G-INTA-01)

JM Fabrications “Race Version” Intake Manifold

The JMF “RACE” version intake manifold is for the daily driven weekend race warriors who want the best of both worlds, more HP without sacrificing a lot of spool and streetability. With over 10 years of proven results, our budget friendly “RACE” version intake manifold is the best bang for you buck. Our latest revision introduces a CNC machined billet runner section that bolts to the plenum for modular functionality. Expected gains can be anywhere from 10-45 HP based on your setup and tuning.

Our manifolds are designed for DSM’s with eliminated EGR. Some modifications to your coil pack mounts and upper intercooler pipes may be needed as this manifold sits down a lot lower than stock. If using the Accufab and other aftermarket throttle bodies please note that the throttle cable and TPS sensors may need modifying.

NEW:These manifolds now have NOS provisions standard. The NOS provisions are a small machined area on the runner section that will allow the end user to drill and tap for NOS nozzles should they have the need. There is a small dimple to mark center but they are NOT drilled so there is no need to plug any holes.
