OEM Acura Spark Plugs

Without spark plugs, the engine in your Acura wouldn't start, let alone run.

All About Acura Spark Plugs

What They Do

Your luxury ride runs on a mixture of oxygen and fuel, but its engine must burn it, and it can't do it without help. Spark plugs, found atop the cylinder head, are what are responsible for igniting the mix, a process which is called "spark ignition."

How They Work

Spark ignition starts when the key turns in the ignition lock cylinder, triggering the ignition switch. The car battery, a starter motor, a starter solenoid, and an ignition coil then collectively generate electricity. The charge travels to the plugs' leads; they capture it, combustion occurs, the engine's pistons pump, its crankshaft turns, and your vehicle's systems start running.

Sadly, spark plugs aren't permanent. Their leads can eventually corrode, for instance -- that is, if they don't otherwise widen far enough that they can no longer conduct electricity properly. They can also weaken physically, and if they do, they can break. When that happens, severe and expensive engine cylinder damage results.

Think yours have problems? There are signs to tell you, and luckily, they usually show up before the worst happens.

The Symptoms They're Failing or Bad

• Look for hard engine starts and a drop in gas mileage
• Listen for engine misfires
• Feel for rough idling and issues accelerating

In any case, run an engine inspection. Replace any spark plugs the results call for. Otherwise, change them according to your owner's manual's recommendations -- before they reach their mileage limits.
