JM Fabrications "Race Version" Intake Manifold | 1990-1994 1G DSM (1G-INTA-01)
JM FabricationsJM 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.

Customer Reviews
Recently installed the JM Fab intake manifold from going from stock to this, for one looks Amazing and fits perfectly like it says even with the Thermal intake gasket. I would say the bolts were a little easier to get to to put them in rather then removing them from the stock intake. Installed the S90 throttle body. Still need to tune vehicle and remove/relocate things so performance wise I won't know just yet
So I had the previous or older race version and decided to get this revised version with the billet runners. So for me the runners are a little shorter and thicker in diameter and I just had a little hard time putting a wrench to the under bolts... so just be patient with a open end wrench or buy new bolts(exact length and threads) with an allen key/hexagonal head screw and go at it with an allen key... either way it was worth taking the time to get this beauty bolted up. I'd recommend as I do not regret this purchase.
Just received this manifold and it is everthing I expected and more... Worth every penny I paid and was shipped to me super fast :) thanks again MAP!
I was expecting to have to wait longer but recieved the manifold less a week after I ordered it. The pictures dont do the manifold justice as this is the latest revised version of the manifold. That being said the staff over at MAP are extremely friendly and always get my orders shipped quickly! I have not installed the manifold yet but have had JMF manifolds in the past the quality has only increased since then!
