A surface gap plug provides exactly what its name describes - a gap at the surface of the combustion chamber. The gap is an annular configuration. The center electrode and insulator tip operate extremely cold (no heat rating) and are therefore nearly impervious to pre-ignition. Power tip X does not use a side ground electrode, eliminating the need for indexing of the spark plug and any gap setting adjustments. This innovative design also reduces the volume of the combustion chamber, increasing the Compression Ratio for enhanced performance. While fouling deposits are always present and cannot burn away, the overall design ensures reliable and efficient operation.

Product Features:

• Power tip X does not use side ground electrode
• No need for indexing of spark plug
• No gap setting to adjust or monitor
• Power tip X reduces the volume of combustion chamber for increased Compression Ratio
• Enhanced Performance: The Autolite Racing Non-Resistor Spark Plug increases the Compression Ratio, delivering superior performance for racing applications.
• Cold Operation: The center electrode and insulator tip operate extremely cold, making the spark plug nearly impervious to pre-ignition.
• Reliable and Efficient: Despite the presence of fouling deposits, the overall design ensures reliable and efficient operation under intense conditions.
