Spark Plugs

Refine Results

Spark plugs are small engine parts, but vital ones for the engine combustion process of your Subaru. Here's how they function, and when to replace them.

Spark plugs are primarily made of a durable aluminum oxide ceramic body that surrounds high-nickel alloy electrode with a steel wire shell. The ceramic body is capable of withstanding extreme temperatures which is needed because the spark plug is the main factor in your engine's combustion process.

There is a spark plug for every cylinder of your engine. They create the spark which ignites the mixture of oxygen and fuel that is needed to get your engine going. Simple, yet technical, spark plugs can reliably last up to 90,000 miles before requiring a replacement.

When to Change Your Subaru Spark Plugs

Like most tiny engine parts, spark plugs are exposed to long periods of heat and over a handful of years or right around the 100,000-mile mark, you should consider replacing all your spark plugs. This will optimize engine performance and keep your car running at a healthy pace. Signs that your Subaru requires a spark plug change are:

  • Engine trouble starting
  • Engine misfires
  • Engine surges
  • Higher fuel consumption
  • Low acceleration
