JMF Dual Port Drag Intake Manifold for Evo 4-9



The JMF "DRAG" version intake manifold is for the hard core racers putting down serious power. If you need one of the highest flowing 4G63 intake manifolds available look no further. Over a year in the making, the JMF DRAG manifold went through a complete overhaul. No corners were cut when it came to the design and functionality of this manifold. Every component on this manifold is CNC machined from billet aluminum, not a single weld is present. Extensive flow testing was conducted on several prototypes until the perfect design was found with the best balance possible.

1996-2006 Evolution IV V VI VII VIII IX

NOS Provisions:
The NOS provisions are a small machined area on the runner section that allows you to drill and tap for NOS nozzles should you need them. There is a small dimple to mark center but they are NOT drilled so there is no need to plug any hol

Install Notes:
JMF manifolds are designed for EVO's with eliminated EGR. Some modifications to your 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. It may be necessary to rotate your throttle body 180° for proper cable clearance. If you need additional vacuum ports our Vacuum Distribution Block is a great option for up to 6 more ports.

MAP Sensor:
The MAP sensor mount is not included, but available below:
JMF MAP Sensor Adapter

If you're running ABS:
The DRAG plenum is large and clearance is tight around the ABS module however the manifold will fit! During the install to minimize contact with the ABS module we recommend either removing the M10 studs in the head and replacing them with bolts or loosening the bracket that holds the ABS module in place allows you to push the module aside just enough to squeeze the intake in place. Once installed there is adequate clearance.

Shipping Times:
Usually ships in 4-6 weeks.
