Full 2F EFI Conversion Kit — Base Adapter + Air Cleaner Adapter (FJ40 & FJ60)

Modern EFI drivability with a factory-correct engine bay — all in one bolt-on package.

This full kit pairs our CNC-milled 2F Intake Manifold Base Adapter (choose FiTech or Holley Sniper thickness) with the 2F Air Cleaner Adapter so you can convert a carbureted 2F to an EFI throttle-body setup while preserving the OEM air cleaner assembly and factory look. The Base Adapter sets the correct throttle-body height for your chosen EFI unit; the Air Cleaner Adapter then allows the original air cleaner housing to sit properly on top.

Why this kit

• This is the ORIGINAL adapter kit and best design for the EFI conversions on Toyota 2F Motors.
• Keeps the classic, factory-correct engine bay while upgrading to modern EFI drivability.
• Bolt-on design — no cutting, welding, or custom fabrication required.
• Precision CNC aluminum construction for a reliable, accurate fit that lasts.

Kit options

Select the Base Adapter that matches your EFI throttle body:

• FiTech option (for FiTech throttle bodies).
• Holley Sniper option (for Holley Sniper throttle bodies).

What’s included

• CNC-milled Aluminum 2F Intake Manifold Base Adapter (FiTech or Holley)
• CNC-milled Aluminum 2F Air Cleaner Adapter
• Mounting hardware for base adapter (to intake manifold)
• Studs and nuts for attaching your EFI throttle body
• Extended stud and hardware for securing the OEM air cleaner housing (reuse OEM M6x1.0 wing nut)
• (Items match the contents listed on each product page.)

Note: Gaskets are not included — we recommend installing a new OEM 2F intake gasket and verifying the condition of any factory air cleaner sealing O-ring before installation.

Compatibility & fitment

• Designed specifically for Toyota 2F engines in FJ40 and FJ60 applications.
• Works with Holley Sniper and FiTech throttle-body EFI systems (throttle bodies sold separately).

Installation notes

• Base adapter selection is required to set proper throttle-body height — choose FiTech or Holley when ordering.
• The kit reuses your factory air cleaner wing nut; no aftermarket wing nut is necessary.
• We recommend replacing the OEM intake gasket and inspecting the air cleaner sealing surface during installation for a reliable dust seal.
