If you’re cruising around in a Honda, you’re probably already aware of its reputation for reliability and efficiency. To keep it that way, you have to maintain it, and one of the items on your checklist should be replacing the spark plugs. These plugs are vital for your engine’s performance, but how often should you have them replaced at your Honda dealer?

Understanding How Spark Plugs Work

These small but mighty components are responsible for creating the spark that ignites the fuel-air mixture in your engine’s cylinders. This ignition is what powers your car, allowing it to start and keeping it running. Over time, your plugs can wear out or become fouled, leading to various engine problems.

Typical Replacement Intervals

The best guide for replacement intervals is your Honda’s owner’s manual since different models and engines have different requirements. However, a general rule of thumb for many modern Hondas is to replace the plugs every 30,000 to 90,000 miles. That’s a big range, influenced in part by whether your car uses conventional or long-life plugs.
Your driving habits and the conditions in which you use your car can also have an impact on this schedule. Frequent short trips, a long time in stop-and-go traffic, or harsh weather conditions can lead to more frequent replacements.

Signs It’s Time for a Change

Engine Misfires

One of the first signs your plugs are starting to wear out is engine misfiring. This can feel like a hesitation or brief pause from your engine while it is running. Engine misfires can cause serious, expensive engine damage, so if you notice this symptom you should have your plugs checked by a professional right away.

Rough Idling

Does your Honda shake or vibrate more than usual when idling? Rough idling can be a symptom of problems with your plugs, where the engine is not running as smoothly due to misfires or incomplete combustion.

Difficulty Starting

Worn or fouled plugs can make it hard to start your car. If you’re noticing that your Honda is becoming increasingly difficult to start, checking your plugs is a good idea.
