Toyota Vios NCP93 (2010) Intake Manifold Description

Engine Model: 1NZ-FE

Material: Composite plastic (main body), with some aluminum components

Configuration:

• 4-cylinder inline
• Natural aspirated
• MPI (Multi-Point Injection)

Key Features:

• Design:
  
• The intake manifold is a plastic resin type, designed for lightweight and efficient air flow.
• It is mounted on the cylinder head, connecting the throttle body to the intake ports.
• 
  
• Airflow Optimization:
  
• Designed with curved runners to improve air velocity and fuel-air mixing.
• Internal flow paths are tuned to enhance low-to-mid range torque.
• 
  
• Vacuum Ports:
  
• Includes several vacuum take-off points for accessories like the brake booster, EVAP system, and PCV (Positive Crankcase Ventilation).
• 
  
• Throttle Body Mount:
  
• The throttle body is bolted to the front of the manifold. It uses a drive-by-wire electronic throttle control system in most variants.
• 
  
• EGR Compatibility:
  
• Certain variants come with EGR (Exhaust Gas Recirculation) port integration for emissions control (varies by region).
• 
  
• PCV Valve Location:
  
• PCV valve is typically mounted directly on the manifold or connected via hose, depending on variant.
