£41.33
The NGK R7437-8 is a spark plug in the NGK Laser Iridium range. It has a laser-welded iridium centre electrode and a platinum pad on the ground electrode, so both wearing surfaces are precious metal.
Use it as a like-for-like replacement where the vehicle handbook specifies this part number. NGK describes the range as original-equipment specification and says this plug type is fitted on the production line by many manufacturers.
