How do iridium electrodes affect performance and durability?

Iridium is used for its high melting point and wear resistance, enabling a finer electrode tip that sustains a consistent spark over many miles. This typically translates into dependable ignitions and longer service intervals compared with standard copper plugs.

• Fine iridium center electrode for faster ignition and stable combustion.
• High-temperature resistance reduces electrode erosion and carbon build-up.
• Rated for longer service life—up to approximately 80,000 km under normal conditions.

Are these plugs ready to install, and what does "OEM fit" mean?

Yes—each plug comes factory pre-gapped to match OEM specifications so they can be installed without gap adjustments for the listed vehicles. "OEM fit" indicates thread size, hex dimensions and reach match original spark plugs for direct replacement.

• Factory pre-gapped for plug-and-play installation.
• Matching dimensions for secure seating and correct heat range.
• Packaged as a 4-pack (sold in a box suitable for replacing all cylinders on many 4-cylinder engines).

What should I expect in terms of maintenance and longevity?

With quality materials and correct installation, these iridium plugs are designed to extend the interval between replacements. Real-world results vary with driving style, engine condition and service environment.

• Typical life expectancy up to around 80,000 km under normal driving conditions.
• Reduced need for frequent replacements compared to copper plugs.
• Less carbon deposition means more consistent performance between tune-ups.

Who is this for? Car owners and independent mechanics who need a cost-effective, OEM-style replacement for worn spark plugs on compatible GM four-cylinder engines will benefit most.
