The process of determining equivalent spark plugs between different manufacturers, specifically from Champion to NGK, involves identifying plugs with similar physical dimensions, heat range, and thread characteristics. This comparison ensures proper fit and function within an engine. For example, a Champion RJ12YC spark plug might be cross-referenced to an NGK B6HS spark plug based on their comparable specifications.
Accurate cross-referencing is crucial for vehicle maintenance and repair, enabling the selection of suitable replacement parts when the original manufacturer’s plug is unavailable or a different brand is preferred. This process also provides historical context, as spark plug technology has evolved, and equivalent models may offer improved performance or longevity compared to older designs. Benefits include broadened part sourcing options, potentially lower costs, and optimized engine operation.
