Fuel economy is diminished.

Inconsistent sparking causes incomplete combustion. Unburned fuel forms a black sooty deposit on the spark plug, eventually leading to poor fuel economy and poor start up of the engine.

Engine power drops on uphill roads and highways.

Poor heat dissipation due to the lack of a copper core center electrode causes pre-ignition. As a result, engine power drops under highway driving or uphill driving conditions.

The plug melts down.

Continued usage of an overheated plug will damage the electrodes.
