Fitment

This listing does not name specific vehicles. Match the part number and the specifications with the part you are replacing.

What it does

Performance manifolds change the runner shape to move power up or down the rev range. Air and fuel parts decide how well the engine breathes and how cleanly it runs, so the right part restores smooth running and can support more power on a modified engine.

Installation & tips

  • Fit new intake gaskets and torque the bolts in sequence to avoid vacuum leaks.
  • Intake manifold gaskets: Always new.
  • Vacuum hoses: Old hoses crack when disturbed.
  • Work on a cool engine with the vehicle secured, and use a service manual for your vehicle for torque specs and procedures.
