How Spark Plugs Work

Spark plugs ignite the mix of fuel and oxygen your engine burns to generate the power it runs on. Without them, your Acura wouldn't be able to start. How they work is straightforward. It's a process called "spark ignition."

The process starts when you turn your key in your ignition lock cylinder. An ignition switch triggers, and your car battery, plus other ignition parts such as an ignition coil, a starter solenoid, and a starter motor, begin working together. They create a small electrical charge -- a "spark" -- which the plugs' leads pick up and use to combust the above-mentioned gas and air. Then, each of your engine pistons pump, your crankshaft begins turning, and the many parts of your Acura get moving.

Signs to Replace Spark Plugs

Unfortunately, though, no spark plug lasts indefinitely. You'll need to replace yours eventually. Look for the signs it's time. First, inspect your plug leads. If they're rusty, or they've widened excessively, they may not be capturing charges properly. If your engine is misfiring or it has failed, these are two other possible signs. If your plugs are broken, though, you should change them immediately, as they can seriously damage your engine cylinders.

How Often to Replace Spark Plugs

Luckily, the spark plugs Acura makes are durable enough to last for millions of ignitions, if not for as many as 100,000 miles. Just don't exceed the mileage limits your owner's manual's maintenance schedule recommends. In other words, be sure to replace any spark plug close to surpassing those limits.
