Plazmaman Big Port Billet Inlet manifold to suit the Mitsubishi 4G63.

Found in the 1st Generation Galant VR4 Series and 1st Generation DSM vehicles overseas. This inlet manifold was designed utilizing over 25 years of experience at the forefront of turbo technology. Plazmaman has taken all the key design areas into account, included ram tube length, taper and inlet volume.

With precision TIG welding by our in-house experts at our Sydney Facility, this allows us to guarantee these inlets with a life time workmanship warranty and a 100psi rating at any rpm level.

These manifolds were primarily designed for Mitsubishi's 1st Generation VR4 (E39A), but we have supplied a number of these manifolds for 4G63 converted vehicles.

This manifold is also available in Rear Wheel Drive application. Contact Us if you’d like application advice or further information.

Plazmaman inlet manifolds utilize some of the most advanced manufacturing techniques. Multi axis HAAS CNC machines ensure that all the one-piece billet bases have tolerances to within .005. The inlet manifold dome uses a hard temper 3mm sheet alloy surface, that has been made to shape in house with advanced forming techniques.

An added feature of these manifolds is that they can be ordered and manufactured specifically to suit 4, or 8 injector operation. For both injector options, we include our CNC machined fuel rails in either single or dual feed. These CNC fuel rails accept 14mm top feed injectors and comes with all mounting hardware, including stainless steel fasteners and CNC spacers/brackets.

Our 4G63 Inlet Manifold can be made to suit a number of our universal or the increasingly popular Bosch Motorsport DBW throttle bodies.

Our billet manifolds are offered with, or without a provision for the factory IAC (idle air controller). A lot of race cars would not run the IAC, as most of these cars are run by independent standalone ECUs.

These manifolds can be supplied in 3 finishes, Raw, Polished, or powercoated Black, for the stealth look.

As with all Plazmaman inlet manifolds, these are packed with many features such as:

  • Lightweight and rigid design.
  • Precision CNC machined billet base.
  • 3mm smooth design plenum dome.
  • Tapered RAM tubed runners.
  • Professionally TIG welded in house by our highly-experienced fabricators.
  • Ergonomic appeal.

*** PLAZMAMAN also has a range of Flow matched fuel injectors available in the Fuel System Section of this online shop - these will make a great addition to your intake purchase . Any Injector you can not see please feel free to email/contact us, as we can source them ***
