NGK 1311 Spark Plug M14 x 1.25 16 mm

The Green Spark Plug Company

The NGK DIFR5C11 is a discontinued spark plug that is no longer manufactured. Where a current equivalent exists it is shown in the alternatives below.NGK Laser Iridium is original-equipment specification: the plug type fitted on the production line by many manufacturers. It pairs a laser-welded iridium centre electrode with a platinum pad on the ground electrode so both wearing surfaces are precious metal, which is what allows the very long service intervals modern engines are scheduled for. Consistent ignition over the life of the plug keeps fuel consumption and emissions where the maker intended. Use it as the like-for-like replacement where the vehicle handbook specifies this part number.
