SKU: TB48 6 INT Category:

Plazmaman's Billet inlet manifold to suit Nissan's incredibly robust TB48DE engine. Designed for tough street/strip conversions or full chassis drag cars running this motor combo.

This intake is best used in conversions or race only vehicles. It is not a direct bolt-in fitment for Nissan Patrols.
This manifold will not fit in a Patrol/Safari without significant modification to the firewall and relocation of other engine bay items.

Contact Us if you'd like application advice or further information.

Our TB48 Billet Inlet Manifold is available in either 6 or 12-injector versions. This billet inlet can be made to suit one of our Plazmaman Universal Billet, or the increasingly popular Bosch Motorsport DBW, throttle bodies, which can be pre-selected prior to ordering.

Also included alongside the manifold is a CNC machined fuel rail or rails (12-injector version), in either single feed, or dual feed. These fuel rails accept 14mm top feed injectors. All fuel rail comes with mounting hardware, including stainless steel fasteners and CNC spacers/brackets.

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

***Some minor under manifold water line modifications will be needed for fitment - on race cars this is removed***

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

  • Built-In Ram Tubes
  • 6061 T65 Aluminium.
  • 6 or 12 Injector options.
  • O-ring port seal design.
  • Precision CNC machined billet base, with hand made 3mm smooth design plenum dome.
  • Professionally TIG welded in house by our highly experienced fabricators.
  • Ergonomic appeal and lifetime structural guarantee.

*** 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 ***
