Spark plugs can seize due to corrosion, over-tightening, or carbon build-up in the threads. This can make them difficult or impossible to remove without damaging the engine. To avoid this, ensure you use anti-seize lubricant on the threads during installation and properly torque them to the manufacturer's specifications. Regular maintenance and timely replacement of spark plugs also help prevent seizing.
