Champion 431 Copper Plus Spark Plug

Manufacturer

Champion

<h3>Over a Century of Ignition Excellence</h3><p>Few names in automotive history carry the weight of <strong>Champion</strong>. Founded in 1905 by Albert Champion in Boston, Massachusetts, the brand has spent more than a century engineering ignition and engine maintenance parts for virtually every combustion engine on the planet. What began as a small spark plug operation grew into one of the most recognized names in the global automotive aftermarket — a brand that has fired engines in everything from the Ford Model T to Formula 1 race cars, the Concorde supersonic jet, and land speed record vehicles.</p><h3>A Legacy Built on Spark Plugs</h3><p>Spark plugs are the heart of the Champion story. Champion spark plugs have been improving engine performance since the earliest days of the automobile, and that tradition continues today with a comprehensive lineup that spans Copper Plus, Platinum Power, Double Platinum, and Iridium technologies. Whether you drive a daily commuter, a powersports machine, a marine vessel, or a lawn-and-garden engine, Champion catalogs a plug engineered for your application. The brand&apos;s Iridium plugs are backed by a 7-year unlimited-mileage guarantee — a testament to Champion&apos;s confidence in its own engineering. Champion has also powered motorsports legends, including victories at Le Mans and Fernando Alonso&apos;s Formula 1 championship season in 2005.</p><h3>Engine Protection Beyond Ignition</h3><p>Champion&apos;s expertise doesn&apos;t stop at the spark. The brand has expanded its aftermarket presence to include Champion air filters, designed to shield your engine from harmful contaminants and keep it breathing cleanly. Champion&apos;s air filter lineup is engineered to meet or exceed original equipment specifications, offering broad coverage across the North American passenger vehicle population. The same philosophy that has guided over a century of spark plug innovation — precision engineering, rigorous testing, and OE-level quality — carries through to every filter Champion produces.</p><h3>Who Champion Serves</h3><p>One of Champion&apos;s greatest strengths is the sheer breadth of its application coverage. The brand serves passenger cars, light trucks, powersports, marine, aviation, industrial, and lawn-and-garden markets. If it has a combustion engine, there&apos;s a strong chance Champion has a part engineered for it. Now operating under DRiV, Tenneco&apos;s aftermarket division, Champion continues to leverage decades of original equipment manufacturing experience to develop parts that perform reliably in the real world.</p><h3>Why Enthusiasts and Professionals Trust Champion</h3><p>Champion&apos;s long-standing reputation is grounded in genuine engineering milestones. The brand was present at some of the most iconic moments in engine-powered history — from powering the world&apos;s first mass-produced automobile to igniting jet fighters and supersonic aircraft. That heritage informs every product Champion brings to market today: parts built with the same commitment to quality, reliability, and performance that made the name legendary.</p>
