Frequently Asked Questions

Why are Iridium spark plugs better than standard copper plugs?

Iridium spark plugs offer superior durability and a much longer lifespan (often 80,000 to 100,000 miles) compared to copper plugs. The fine Iridium tip allows for a more consistent and powerful spark, improving fuel efficiency and engine performance.

Can I install these spark plugs myself?

Yes, spark plug replacement is a common DIY task. Most modern spark plugs, including those listed, come pre-gapped. You will need a spark plug socket and a torque wrench to ensure they are installed correctly and securely.

What is the benefit of a full ignition coil and spark plug kit?

A full kit ensures that both the coils (which provide the high voltage) and the plugs (which ignite the fuel) are new and matched. Replacing both simultaneously eliminates potential weak points in the ignition system, leading to smoother performance and fewer future maintenance issues.
