Description
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, teh 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 they found the perfect design with the best balance possible.
Features:
- Made form 6061-T6 aircraft quality aluminum
- CAD designed
- Fully CNC machined components, no welds
- Modular bolt together design for cost effective upgrades from our street/race versions
- 15° throttle body inlet eliminates turbulence and adds more intercooler pipe clearance
- CNC machined velocity stacks
- Tapered runners
- 5.68L Plenum Volume
- O-ring'd head flange eliminates the need for a gasket
- 5 port vacuum plate with 1/4" NPT threads
- NOS provisions standard
- Several different finishes and throttle body flange options available
- Limited Lifetime Warranty
Includes:
- DRAG version intake manifold
- Adjustable throttle cable bracket (except Bosch and RWD)

- (1) 1/8" brass hose barb
- (1) 1/4" NPT brass plug
- Stainless steel throttle body bolts

Note: 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. We highly recommend running 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.
