What is the spark plug gap for a Toyota Tacoma?
Understanding the correct spark plug gap for your Toyota Tacoma is essential for optimal engine performance. Spark plugs play a crucial role in igniting the air-fuel mixture in the engine's combustion chamber, and the gap between the electrodes can significantly affect engine efficiency, fuel consumption, and emissions. In this article, we will explore the recommended spark plug gap for various Toyota Tacoma models and provide tips on how to check and adjust it.
Recommended Spark Plug Gap
The spark plug gap for a Toyota Tacoma typically varies depending on the engine type and model year. For most models, the recommended gap is:
- 2.5L 4-cylinder models: 0.043 inches (1.1 mm)
- 4.0L V6 models: 0.043 inches (1.1 mm)
It's important to consult your owner's manual or a reliable service guide for the specific model year of your Tacoma, as there may be slight variations based on engine specifications.
How to Check and Adjust Spark Plug Gap
Checking and adjusting the spark plug gap is a straightforward process that can be done with a few simple tools. Here’s how to do it:
- Gather your tools: You will need a spark plug gap tool or feeler gauge, a socket wrench, and possibly a torque wrench.
- Remove the spark plug: Use the socket wrench to carefully unscrew the spark plug from the engine.
- Measure the gap: Insert the feeler gauge into the gap between the electrodes. If it fits snugly, the gap is correct. If it’s too tight or too loose, adjustments are needed.
- Adjust the gap: If the gap is incorrect, gently bend the ground electrode to achieve the desired gap measurement.
- Reinstall the spark plug: Once adjusted, reinstall the spark plug, ensuring it is tightened to the manufacturer’s specifications.
Conclusion
Maintaining the correct spark plug gap in your Toyota Tacoma is vital for ensuring your vehicle runs smoothly and efficiently. Regular checks and adjustments can help prevent engine misfires and improve fuel economy.

What is the gap on a factory spark plug?
The gap setting is different for each vehicle but most are somewhere between 0.028" and . 060".
What happens if spark plugs are not gapped correctly?
The incorrect plug gap for your engine can contribute to a high rate of misfires, loss of power, plug fouling, poor fuel economy and accelerated plug wear. It is always best to check the gap against the manufacturer's specifications.
What happens if the spark plug gap is too big?
Consequences of Incorrect Spark Plug Gap
Too small of a gap may give too weak of a spark to complete the combustion process within the engine; too wide of a gap can lead to the spark plug not firing correctly, causing misfires at high speeds.
What is the spark plug gap on a 2002 Toyota Tacoma?
Toyota recommends NGK# BKR5EYA (which are single electrode) spark plugs. The gap is 0.8mm. Most spark plug brands such as NGK or Bosch usually come pre-gapped.
What is the correct spark plug gap?
between 0.028″ and 0.060″
To put it simply, the gap is the space between the central and side electrodes. This spacing is pivotal, dictating the spark intensity, which is crucial for efficient combustion. Vehicle manuals provide the ideal gap, which usually ranges between 0.028″ and 0.060″.
What is the spark plug gap on a 3.5 L V6?
Engine Specifications
| Engine | 2.7L EcoBoost | 3.5L V6 TiVCT |
|---|---|---|
| Required fuel | Minimum 87 octane | Minimum 87 octane or E85 |
| Firing order | 1-4-2-5-3-6 | 1-4-2-5-3-6 |
| Ignition system | Coil on plug | Coil on plug |
| Spark plug gap | .028-.031 (0.7 - 0.8 mm) | .049-.053 in. (1.25 - 1.35 mm) |
What is the gap size for spark plugs on a Toyota?
Electrode gap 1.0 - 1.1 mm (0.039 - 0.043 in.)
What is the spark plug gap on a 3.4 L Toyota?
. 44 is the gap.
Are OEM spark plugs gapped?
Since the gap size has a direct effect on the voltage necessary to jump the gap and ionize (light) the air-fuel mixture, careful attention is required. While plugs are pre-gapped from the factory, the gap may need to be adjusted for the vehicle that the spark plug is intended for.
