NGK Laser Iridium Spark Plug ILKAR7C10 for Jaguar F-Type/XF/XJ/XK and Land Rover Range Rover/Range Rover Sport/LR4 (2010–2020)

NGK part 94940 is a Laser Iridium spark plug, NGK code ILKAR7C10, that ignites the air-fuel charge in each cylinder of supercharged and naturally aspirated Jaguar and Land Rover models from 2010 to 2020. NGK manufactures this plug in Japan at OE quality. It cross-references to Jaguar and Land Rover numbers C2P23089, LR032080, LR011987, and LR019484, which is useful when you are matching a plug pulled from the engine or a number from a service record. The Laser Iridium name refers to NGK's iridium-tipped plug line. Coverage runs from the F-Type, XF, XFR, XFR-S, XJ, XJR, XJR575, XK, XKR, and XKR-S on the Jaguar side to the Range Rover, Range Rover Sport, and a single LR4 model year on the Land Rover side.

This NGK spark plug carries a 24-month or 24,000-mile warranty.

Several Jaguar and Land Rover plug numbers point to this one NGK part, and C2P23089 is also shared with a later NGK plug that covers newer models. Because of that overlap, go by the vehicle and year rather than the Jaguar or Land Rover number alone. A spark plug delivers the high-voltage spark from the ignition coil across its electrode gap, and its electrodes slowly erode over thousands of firing cycles. When a plug is worn, NGK and Jaguar Land Rover owners commonly see misfiring, a check engine light, hesitation, loss of power, or poor fuel economy.
