JMF Drag Intake Manifold for 1G DSM




The JMF 1G "DRAG" version intake manifold is for hard core racers putting down serious power. If you need one of the highest flowing 4G63 intake manifolds available look no further! 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 with the best balance possible was achieved.

Install Notes:
Some modifications to your coil pack mounts and upper intercooler pipes may be needed as this manifold sits down a lot lower than stock. Drag version will not work with OEM fuel filter and cruise control. It is highly recommended to run at least a 74mm throttle body with this manifold. If using the Accufab and other aftermarket throttle bodies please note that the throttle cable and TPS sensors may need modifying. If you need additional vacuum ports, the JMF Vacuum Distribution Block is a great option for up to 6 more ports.
