4AGE Toyota Small & BIG Port

Plazmaman Billet Inlet manifold to suit the Toyota 4AGE Small and Big Port 

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.

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.

Our 4AGE  Inlet Manifold can be built for and supplied with a number of our Plazmaman universal billet throttle bodies or the increasingly popular Bosch Motorsport Drive-By-Wire units, which can be selected prior to ordering.

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.
• O-ring port seal design.
• Tapered RAM tubed runners.
• Professionally TIG welded in house by our highly-experienced fabricators.
• Ergonomic appeal.
• Optional Plazmaman Billet Fuel rail.
• LIFETIME WARRANTY
