About the product
The NGK DILFR7B10G 97218 is a Laser Iridium spark plug with a 12 mm diameter.
It has a laser-welded iridium centre electrode and a platinum pad on the ground electrode, giving both wearing surfaces precious-metal construction. The plug is described as original-equipment specification and is the type fitted on production lines by many manufacturers.
Use it as a like-for-like replacement where the vehicle handbook specifies this part number. Its design allows for the very long service intervals scheduled for modern engines. Consistent ignition over the plug's life keeps fuel consumption and emissions where the vehicle maker intended.
