JM Fabrications: 1G DSM Drag Version Intake Manifold

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, our 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 we found the perfect design with the best balance possible.
