The engine in your Land Rover SUV can't burn fuel and oxygen for power without spark plugs. They're what start the combustion process. Turn your key in the ignition lock cylinder, and you'll see how that process works: first, the ignition switch triggers, and many other ignition parts, from your battery and starter motor to your starter solenoid and ignition coil, work to send electricity to the plugs' leads. Second, when the "spark" reaches them, the engine's complement of air and gas ignite, releasing power. Finally, the engine's pistons and crankshaft get moving, and the many other parts that drive your vehicle get going.
Without spark plugs, though, no vehicle, Land Rover or otherwise, could start at all, and even the best can go bad sooner or later. Signs of that include rusted or overly widened leads, weak conductivity, engine misfires, and a complete engine shutdown. Broken spark plugs, however, do a lot worse: they can damage an engine's cylinders severely.
Luckily, those manufactured these days are built to last, up to approximately 100,000 miles and for millions of ignitions - they'll just need to be replaced before they near their recommended mileage limits. The question becomes "what spark plugs do I need?" That depends on your Land Rover model. The genuine article works best either way.
