What is the spark plug gap for a Honda?
The recommended spark plug gap for most Honda vehicles is between 0.028 and 0.031 inches (0.71 to 0.79 millimeters). This gap setting is crucial for proper engine performance and fuel efficiency in Honda cars, trucks, and SUVs.
Understanding Spark Plug Gaps
The spark plug gap refers to the distance between the center electrode and the ground electrode of a spark plug. This gap allows the electrical current to jump across and create the spark that ignites the air-fuel mixture in the engine cylinder. The optimal gap size varies by vehicle make, model, and engine type, as it affects factors like ignition timing, combustion efficiency, and engine wear.
Spark Plug Gap for Honda Vehicles
Honda recommends a spark plug gap range of 0.028 to 0.031 inches (0.71 to 0.79 mm) for most of its passenger vehicles, including the Accord, Civic, CR-V, Pilot, and Odyssey. This gap setting helps ensure reliable ignition and proper fuel combustion in Honda's engines, leading to improved performance, fuel economy, and emissions control.
It's important to note that some Honda models may have slightly different spark plug gap specifications, so it's always best to refer to the owner's manual or contact a Honda dealer for the exact recommended gap for a particular vehicle.
Checking and Adjusting the Spark Plug Gap
- Use a spark plug gap tool or feeler gauge to measure the gap between the center and ground electrodes.
- If the gap is too wide, carefully bend the ground electrode inward to decrease the gap.
- If the gap is too narrow, bend the ground electrode outward to increase the gap.
- Recheck the gap after any adjustments to ensure it falls within the 0.028 to 0.031 inch (0.71 to 0.79 mm) range.
Maintaining the proper spark plug gap is a simple but important maintenance task for Honda owners to ensure their vehicle runs at its best. Following the manufacturer's recommendations will help optimize engine performance, fuel efficiency, and emissions control.
What is the spark plug gap on a 3.5 L Honda?
On the 2008 Honda Odyssey with the V6-3.5L engine, the spark plug gap is: 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 is the spark gap on a 2014 Honda Accord?
Gap 0.043". Quantity per car: 4.
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 |

| Spark plug gap | .028-.031 (0.7 - 0.8 mm) | .049-.053 in. (1.25 - 1.35 mm) |
What is the spark plug gap on a Honda?
0.039-0.044 inches
The proper spark plug gap should be: The spark plug gap should be 0.039-0.044 inches (1.0-1.1mm).
What is the rule of thumb for spark plug gap?
Consult a recommendation list or vehicle manufacturer's handbook for individual gap settings. The rule of thumb for the spark plug gap on older engines is coil ignition 0.025 thou and magneto ignition 0.018 - 0.020 thou.
What happens if your spark plugs are gapped wrong?
Any spark plugs that are gapped incorrectly can result in poor engine performance by altering engine combustion, weakening the ignition spark, and delaying the arcing of the ignition spark as it crosses each spark plug diode.
What happens if spark 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 NGK spark plugs already pre gapped?
While most NGK spark plugs are pre-gapped, there are occasions when the gap requires adjustment. Care must be taken to avoid bending or breaking off the fine-wire electrodes. NGK recommends a round wire-style or pin gauge gap tool to measure the gap.
Are ngk spark plugs pre-gapped on a Honda?
Although the NGK factory will set the gap to a preselected setting, this may not be the right gap for your particular engine.
