What is the spark plug gap for a Toyota Tacoma?
The recommended spark plug gap for a Toyota Tacoma is 0.032 to 0.036 inches (0.81 to 0.91 millimeters). This gap ensures optimal engine performance and fuel efficiency for your Tacoma. Properly gapping the spark plugs is an important maintenance task that should be performed regularly to keep your truck running at its best.
Understanding Spark Plug Gaps
The spark plug gap refers to the distance between the center electrode and the ground electrode on a spark plug. This gap allows the spark to jump across and ignite the air-fuel mixture in the engine cylinder. If the gap is too wide, the spark may have difficulty jumping across, leading to misfiring and poor engine performance. Conversely, if the gap is too narrow, the spark may not be strong enough to fully ignite the mixture.
Recommended Spark Plug Gap for Toyota Tacoma
According to Toyota's specifications, the recommended spark plug gap for a Tacoma is 0.032 to 0.036 inches (0.81 to 0.91 millimeters). This gap setting is designed to provide the optimal balance between ignitability, fuel efficiency, and engine longevity for the Tacoma's engine.
How to Check and Adjust the Spark Plug Gap
To check and adjust the spark plug gap on your Toyota Tacoma, follow these steps:
- Locate the spark plugs, which are typically accessible from the top of the engine.
- Use a spark plug gap tool or feeler gauge to measure the gap between the center and ground electrodes.
- If the gap is not within the recommended range of 0.032 to 0.036 inches, carefully bend the ground electrode to adjust the gap as needed.
- Reinstall the spark plugs and torque them to the specified value, typically around 13 to 18 ft-lbs (18 to 24 Nm).
Properly gapping the spark plugs is an important maintenance task that can help ensure your Toyota Tacoma runs at its best. By following the manufacturer's recommended spark plug gap, you can optimize engine performance, fuel efficiency, and overall vehicle reliability.
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 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 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.
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.
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 spark plug gap on a 3.4 L Toyota?
. 44 is the gap.
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.
