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.
More than 30 years ago, Champion pioneered the use of iridium in the manufacture of spark plugs because of its excellent wear characteristics and stabilizing effect on ignition voltage. Today Champion Iridium spark plugs offer maximum performance for a wide array of engines. Every iridium spark plug by Champion has a fine-wire iridium center electrode, and “laser-locked” platinum V-trimmed ground electrode, which ensures a consistently focused spark, the longest service life, and greatest erosion resistance. These products also reach operating temperatures quickly and maintain stable operating temperatures under varying engine loads thanks to their exclusive Heat-Active alloy.
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.
