Spark plugs are used to ignite the air / fuel mixture in the engine
The ( 8 ) spark plugs ( in your navigator ) are needed for the engine to run properly
For example : if the engine cranks but does not start the engine is either not getting fuel , SPARK , or air
Another example is if an engine cylinder is " missing " so the engine is running rough the cause may be the SPARKPLUG , coil , not the correct air / fuel ratio etc.
The coils are bolted to the side of the engine, The spark plugs are under the coils, NO PLUG WIRES. unbolt the coils and use A spark plug socket.
