£11.83
The NGK SIFR6A11 Laser Iridium is a spark plug with a 14 mm diameter and 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. Use it as a like-for-like replacement where the vehicle handbook specifies this part number. The source also states that consistent ignition over the plug's service life keeps fuel consumption and emissions where the maker intended.
