Original Toyota Spark Plugs Online

Spark plugs play a key role in your engine’s ignition system, generating the spark that ignites the air-fuel mixture inside each cylinder. A worn or faulty spark plug can lead to misfires, lower fuel efficiency, and sluggish performance.

What Are the Types of Spark Plugs for a Toyota Prius?

Spark plugs are made from different materials, and each type affects how long the plug lasts and how it performs. For your Toyota Prius, here are the most common types available:

Types of Spark Plugs by Material

Copper Spark Plugs

These are the most affordable option and offer strong conductivity, but they wear out faster.

Platinum Spark Plugs

Platinum plugs last longer than copper and provide better fuel efficiency thanks to a higher melting point and more stable performance.

Double Platinum Spark Plugs

These feature platinum on both the center and ground electrodes for improved durability and are ideal for wasted-spark ignition systems.

Iridium Spark Plugs

These plugs offer precise ignitability and are commonly recommended for modern Toyota engines.

Ruthenium Spark Plugs

The newest type on the market, ruthenium plugs combine long life and high performance, making them a great fit for fuel-efficient hybrids like the Prius.

Other Key Parts for Best Prius Engine Performance

When replacing spark plugs, inspect your air filters, as well. A clean filter helps maintain peak combustion and protects your engine from debris.
