£9.41
The NGK ILKAR7A7 91432 is a Laser Iridium spark plug with original-equipment specification.
It has a laser-welded iridium centre electrode and a platinum pad on the ground electrode, making both wearing surfaces precious metal. The plug is described as part of the NGK Laser Iridium range, which is fitted on the production line by many manufacturers.
Use it as a like-for-like replacement where the vehicle handbook specifies this part number. The stated construction allows the long service intervals scheduled for modern engines. Consistent ignition over the plug’s life keeps fuel consumption and emissions where the maker intended.
