Champion Spark Plugs Stock Number 694, Type C53VC, Gasket Seat , 5/8" Hex , 14mm Thread 3/4"Reach , Champion? Racing Plugs Non-Resistor Spark Plug This Racing spark plug is recommended for high horsepower, high boost and Alcohol based fuels (ethanol) It will run smoother, is harder to foul, and helps burn more of the combustion charge due to it's totally open spark kernel. Please Read the Following - These may not be the plugs for you! Don't get them because they are the "new thing on the block" These are very cold race plugs. So you may not run enough heat through your engine to utilize this type of plug. If you are using an HKS DLI you should not use these spark plugs. The DLI requires resistor type spark plugs. A surface gap plug provides exactly what its name describes... a gap at the surface of the combustion chamber. The gap is a .050" annular configuration. The center electrode and insulator tip operate extremely cold (no heat range rating) and are, therefore, nearly impervious to pre-ignition. However, fouling deposits are always present and cannot burn away. These types have limited use in racing. A special ignition system with very high energy and a very fast rise time (CD) is required to fire the gap when fouling deposits are present. The insulator tip does not operate hot enough to allow reading of the spark plug during engine tuning. C53VC are designed for small-block Ford and Chevy engines used in Winston Cup type racing. |
