OEM Subaru Spark Plugs

Refine Results

The engine in your Subaru wouldn't even start, let alone run, without spark plugs. There's a lot to learn about them. Get all the details, right here.

Subaru Spark Plugs FAQ

What Do They Do?

They ignite the mixture of oxygen and fuel in your engine, producing the power the car or SUV you love runs on.

How Do They Work?

The process is called "spark ignition." It works as follows.

  • Your key turns in the ignition lock cylinder.
  • An ignition switch activates.
  • The car battery, a starter motor, a starter solenoid, and an ignition coil work together to generate electricity.
  • The charge travels to the plugs' leads.
  • When it reaches them, they capture it, and combustion occurs.
  • The engine's pistons pump, its crankshaft turns, and your vehicle starts up and, with a little help from the alternator, stays running.

What are the Signs They're Going Bad?

Sadly, no spark plug lasts forever. For example, their leads can corrode or widen. This makes it so that they can't conduct electricity as well.

They can also weaken physically and break. If that happens, it's a worst-case scenario: severe engine cylinder damage results. Ditto for an expensive repair.

If you think your spark plugs may have problems, look for:

  • Hard engine starts
  • A marked reduction in gas mileage
  • A misfiring engine
  • Rough idling
  • Trouble speeding up

If you experience any such symptoms, run an engine inspection, replacing any spark plugs you have to. Otherwise, change them when your owner's manual recommends doing so -- before they reach their mileage limits.

If you're looking to buy some online, choose genuine Subaru.
