A properly designed spark plug takes the high voltage generated by the ignition coil and creates the spark needed to jump across the gap and start combustion. It also seals the combustion chamber and transfers the heat it picks up in the combustion process to the cylinder head and into the cooling system. When a spark plug provides these three basic functions, it is then capable of initiating and sustaining the combustion process thus ensuring effective engine operation. To make these spark plugs meet these requirements as well as provide superior performance and long life, Champion engineers employed a vast amount of technology into the design and manufacturing process.
To meet OE standards and specifications, these spark plugs are made of premium quality materials and are also tested to ensure they deliver a consistently focused spark that optimizes performance. Champion engineers also use thermocouple spark plugs to read electrode temperatures and the engine expertise of Federal-Mogul engine research centers to determine the proper heat range for each application and ensure that these products meet the requirements of your vehicle. Whether you want to replace your worn out or damaged platinum spark plug or upgrade a vehicle originally equipped with standard nickel/copper type plugs, these spark plugs are an excellent choice.
With a platinum tip welded to a nickel alloy center electrode, these products last long while maintaining the gap setting over their lifespan, which means the voltage to fire the spark plug is kept at consistent levels, reducing the chance of misfire. Thanks to an ideal combination of a thin-wire center electrode with a V-trimmed ground electrode, spark scattering is kept to a minimum. By creating sharp spark focus and less spark scatter, this electrode combination ensures better engine performance compared to a traditional spark plug. The electrodes also use an exclusive Heat-Active alloy that allows the plugs to reach operating temperature quickly and maintain stable operating temperatures under varying engine loads.
For over 100 years, Champion® has been a world leader in the manufacture of spark plugs for a wide range of cars, SUVs, trucks, racing, and marine applications. Using the latest technology, from iridium and precious metal technologies, to F.I.S.S. resistor (Fired In Suppressor Seal) technology and MLR (Metal alloy Low ohm Resistor) technology, the company develops, engineers, and manufactures spark plugs in a number of materials and designs. Champion also offers a variety of glow plugs, spark plug wires, and other ignition system specific wiring that meet the industry’s toughest standards.
