NGK R0373A 11 5566 Spark Plug Racing R0373A11

The NGK R0373A-11 is part of the NGK Laser Iridium range.NGK Laser Iridium is original-equipment specification: the plug type fitted on the production line by many manufacturers. It pairs a laser-welded iridium centre electrode with a platinum pad on the ground electrode so both wearing surfaces are precious metal, which is what allows the very long service intervals modern engines are scheduled for. Consistent ignition over the life of the plug keeps fuel consumption and emissions where the maker intended. Use it as the like-for-like replacement where the vehicle handbook specifies this part number.

Designed for motorsport use: Specially developed and produced for the extreme conditions of racing. Specially developed earth electrode material and shape to withstand higher temperatures, pressures and vibrations in the combustion chamber. Highest load capacity: Extreme heat protection and vibration to resistance to withstand higher loads. Note: Please observe the general fitting instructions before installation!
