£21.58
The NGK SILMAR9A9S 6213 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. This plug is intended as a like-for-like replacement where the vehicle handbook specifies this part number. The source describes the Laser Iridium range as having precious metal on both wearing surfaces and says consistent ignition over the plug’s service life keeps fuel consumption and emissions where the maker intended.
