Product Usage

Components of a Spark Plug:

 *A metal terminal that connects to the ignition system.

*A center electrode for current to flow through the spark plug with a tip for the current to jump making the spark.

 *A ribbed ceramic insulator to keep current flowing through the spark plug center electrode and not into other parts of the engine.

*A threaded metal case to anchor the spark plug into the cylinder head with a ground electrode for the spark to jump. 

 *A seal to seal the spark plug case to the cylinder head to prevent cylinder compression from escaping.

•  

 

Periodic spark plug replacement prevents many common problems caused by worn, contaminated plugs, including misfire, reduced power and fuel economy, and an illuminated Check Engine Light. Fresh plugs promote good engine performance and fuel economy, whilereducing engine misfire that stresses and damages expensive ignition coils and catalytic converters.

Most engines are designed to run on only one type of spark plug based on its use. Be sure to check your owner's manual for the right type of spark plug needed for your BMW.
