The NGK SILFER8C7ES is an iridium spark plug in the NGK Laser Iridium range, with part number 94712.
It pairs a laser-welded iridium centre electrode with a platinum pad on the ground electrode, making both wearing surfaces precious metal. Use it as a like-for-like replacement where the vehicle handbook specifies this part number.
The range is described as original-equipment specification: the plug type fitted on the production line by many manufacturers. Consistent ignition over the plug’s life keeps fuel consumption and emissions where the maker intended, and the precious-metal wearing surfaces allow the long service intervals scheduled for modern engines.
