What is the spark plug gap for a 2007 Toyota FJ Cruiser?
The spark plug gap for a 2007 Toyota FJ Cruiser is typically 0.043–0.047 inches (1.1–1.2 mm).
The 2007 FJ Cruiser uses the 4.0-liter 1GR-FE V6. For this engine, the widely accepted gap range stays within about 0.043–0.047 inches (1.1–1.2 mm) for both OEM and many aftermarket plugs. Using a plug with a gap outside this range can affect ignition performance, fuel efficiency, and overall engine smoothness, so check the exact spec for the plug you install.
Gap specification for the 1GR-FE engine
Here is the guideline most commonly cited for this engine family. Toyota service literature and typical aftermarket guidance align on a narrow gap around 0.043–0.047 in (1.1–1.2 mm). If you’re using a non-OEM plug, always confirm its specific gap requirement from the plug manufacturer.
Recommended gap range
The standard gap for the 1GR-FE engine in the FJ Cruiser, including OEM plugs and many aftermarket options, is 0.043–0.047 inches (1.1–1.2 mm). Some plug types (especially certain iridium or platinum designs) may specify the same or a very similar gap; always verify the plug’s own specification before installation.
How to measure and adjust the gap
To ensure accuracy, measure the gap with a proper feeler gauge and adjust if necessary. The following steps outline a safe, common approach. Before any work, ensure the engine is cool and disconnect the negative battery terminal when removing plugs.
- Remove the spark plug from the cylinder head using a spark plug socket and a suitable extension; inspect the plug for wear or fouling.
- Use a feeler gauge to compare the actual gap to the target range of 0.043–0.047 inches (1.1–1.2 mm).
- If the gap is outside the range, adjust by carefully bending the ground electrode with a precise spark plug gap tool, or replace the plug with one that has the correct gap.
- Reinstall the plug and torque to the manufacturer’s specification using a torque wrench; consult the service manual for the exact value for your plugs and engine.
Maintaining the correct gap promotes proper ignition timing, smoother idle, and optimal combustion. Using plugs with an incorrect gap can lead to misfires, reduced performance, and higher fuel consumption.
Summary
For a 2007 Toyota FJ Cruiser, the spark plug gap is generally 0.043–0.047 inches (1.1–1.2 mm). Always verify with the plug manufacturer’s specifications and follow the Toyota service manual for proper torque when installing. If in doubt, consult a qualified technician.
