Champion Spark Plugs

When it comes to spark plug manufacturing, few names carry the heritage and proven performance of Champion. For over 100 years, Champion has been a world leader in the manufacture of spark plugs for every kind of combustion engine, establishing a reputation built on innovation that extends from aviation to motorsports to everyday automotive applications.

Engineering Excellence in Spark Plug Design

Champion's approach to spark plug engineering reflects decades of specialized research and development. Champion uses a proprietary approach in designing their automotive spark plugs, from the use of iridium and precious metal technologies, to F.I.S.S. resistor technology and MLR™ technology. This engineering philosophy ensures that whether you're replacing plugs in a daily driver or building a high-performance engine, Champion offers solutions tailored to specific ignition requirements.

Almost 30 years ago, Champion established the use of iridium in aviation and industrial applications, now offering ultimate performance regardless of ignition or engine type. Their iridium spark plugs feature center electrodes paired with platinum ground electrodes, delivering maximum plug life and sharp spark focus for reliable ignition across varying engine loads.

Comprehensive Product Range

Champion's spark plug lineup addresses every performance tier and application need. The Iridium series represents the pinnacle of their technology, utilizing precious metals that resist wear and maintain precise gaps over extended service intervals. The Double Platinum Power line features platinum on both the center and ground electrodes, ensuring longer life and durability. For vehicles originally equipped with standard technology, the Platinum Power plugs offer an excellent upgrade path with enhanced heat dissipation and focused spark delivery.

The Copper Plus series continues Champion's tradition of reliable OE-replacement solutions. Champion's introduction of a copper core electrode improved the plug's ability to conduct electricity and provided a more reliable spark for ignition, a design innovation that remains relevant for older automotive engines, lawn equipment, and small engine applications.

Proven in Extreme Conditions

Champion's spark plug technology has been validated in some of the world's most demanding environments. Richard Noble drove the extraordinary Thrust 2 across the Black Rock desert to become the fastest man on earth, fired by Champion ignitors, achieving 633mph. From Formula 1 victories to Le Mans endurance racing, Champion spark plugs have demonstrated their ability to perform when precision ignition matters most.

Proven expertise in engineering and manufacturing OE components for the world's major automotive manufacturers translates into innovative maintenance solutions for professional repair technicians, do-it-yourselfers and performance enthusiasts. This OE experience ensures proper fit, form, and function for modern ignition systems while maintaining backward compatibility with classic vehicles.

Innovation Rooted in History

In 1931, Champion introduced its first suppressor-type spark plugs, using a carbon-based resistor to reduce the effects of ignition noise on radio waves—an early example of the brand's commitment to solving real-world problems through engineering innovation. That same spirit drives their contemporary technologies, including exclusive Heat-Active alloys that ensure operating temperatures are quickly reached and maintained even with varying engine loads, optimizing combustion efficiency and reducing emissions.

Whether you're performing routine maintenance or seeking performance gains, Champion spark plugs combine proven metallurgy, precision manufacturing, and over a century of ignition expertise into products designed to meet the exacting standards of today's engines.
