NGK WR5IX 7510 Spark Plug Iridium IX
£10
£12.25
The NGK GR7CI-8 is a Laser Iridium spark plug with a 14 mm diameter. It has a laser-welded iridium centre electrode and a platinum pad on the ground electrode, making both wearing surfaces precious metal.
NGK describes the range as original-equipment specification, meaning this is the plug type fitted on the production line by many manufacturers. Use it as a like-for-like replacement where the vehicle handbook specifies this part number, 95476.
Consistent ignition over the life of the plug keeps fuel consumption and emissions where the vehicle maker intended, and the construction allows for the very long service intervals scheduled for modern engines.
