Infiniti M35 Spark Plugs

Without spark plugs, the engine in your INFINITI M35 wouldn't start. After all, their job is to ignite the mixture of oxygen and fuel your favorite luxury sedan runs on. The process is called "spark ignition."

It works like this. First, your key turns in the ignition lock cylinder. Then, an ignition switch triggers. Finally, the car battery, a starter motor, an ignition coil, and a starter solenoid generate electricity. The charge travels to the plugs' leads. When it reaches them, they capture it. Combustion occurs, and the engine's pistons start pumping, its crankshaft turns, and your vehicle starts running on its own power.

Sadly, though, spark plugs aren't permanent. Their leads can corrode or widen, for instance. This makes it so they can't conduct electricity properly anymore. The plugs themselves can also weaken physically. If they do, they invariably break. When that happens, severe (and costly) engine cylinder damage results.

If you think yours have problems, a few signs will tell you. Luckily, they show up before the worst happens, most of the time. Look for:

• Hard engine starts
• Worsening gas mileage
• Engine misfires
• Rough idling
• Trouble accelerating

If you see any, run an engine inspection and replace any spark plugs you need to. Otherwise, change them before they reach their mileage limits, according to the recommendations in your owner's manual.
