The NGK IFR5E11 7994 is a spark plug in the NGK Laser Iridium range. Its centre electrode is laser-welded iridium, and the ground electrode has a platinum pad, so both wearing surfaces are precious metal.
Use it as a like-for-like replacement when the vehicle handbook specifies this part number. The source describes the range as original-equipment specification and notes that modern engines may be scheduled for very long service intervals with these plugs.
