Genuine Honda Spark Plugs

Honda Spark Plugs: What You Need to Know

What They Do

They ignite the mix of air and fuel in your vehicle's engine, so it can burn it to produce the power the vehicle runs on. In short, they help start your Honda.

How They Work

The process is called spark ignition. It starts when your key turns in its ignition lock cylinder. An ignition switch triggers, and your battery, starter motor, starter solenoid, and ignition coil generate electricity.

The charge travels to the plugs' leads; they capture it, and combustion occurs. Your engine's pistons then start to pump, and its crankshaft begins turning. Most importantly, your vehicle's many systems start running.

The Symptoms of Failing or Bad Ones

Sadly, none are permanent. For instance, their leads can corrode, that is, if they don't otherwise widen too far for proper conductivity. Worse yet, they can physically weaken, and if they do, they can break -- a worst-case scenario that almost always results in severe and expensive engine cylinder damage.

Think you've got spark plug problems? There are signs to tell you, and they usually show up before things get worse. They include:

• Hard starts
• Engine misfires
• Trouble accelerating
• Rougher idling than usual
• Worsening fuel efficiency

If you see any of them, inspect your engine and replace any spark plugs necessary according to the results. Otherwise, be sure you change them before they reach their recommended mileage limits.
