The letters on Champion spark plugs indicate various specifications and features, including heat range, thread size, and design characteristics. For example, the first letter often represents the type of plug (e.g., "R" for resistor), while subsequent letters and numbers provide information on the heat range and other design aspects. This coding helps users select the appropriate spark plug for specific engine types and performance needs. Understanding these letters ensures optimal engine performance and longevity.
