Frequently Asked Questions

Answers to Common Questions About Our Spark Plugs

What is a Double Iridium Spark Plug?

A Double Iridium Spark Plug features an ultra-fine iridium alloy tip on the center electrode and a platinum tip on the ground electrode. This design improves ignitability, extends service life, and offers superior resistance to fouling, making it ideal for direct fuel injection engines.

How do Iridium Spark Plugs improve engine performance?

Iridium spark plugs use a finer center electrode (typically 0.7mm) which reduces the voltage required for ignition, improves spark concentration, and enhances combustion efficiency. This leads to better fuel economy, smoother acceleration, and improved overall engine performance.

Are your spark plugs suitable for lawn mowers and small engines?

Yes, we manufacture specialized Lawn Mower Spark Plugs with ultra-fine iridium electrodes that dramatically improve ignitability and lifespan in small engines. These plugs are designed for reliable starting and long-term durability in outdoor power equipment.

What quality certifications do you have?

Our products have passed ISO/TS 16949 quality management certification, which is the international standard for automotive production and service parts organizations. This certification demonstrates our commitment to quality, consistency, and continuous improvement.

What applications are your spark plugs designed for?

Our spark plugs are suitable for a wide range of applications including automotive, motorcycle, ATVs, snowmobiles, marine inboard and outboard engines, personal watercraft, generators, compressors, and other industrial equipment.
