What to do when you change spark plugs?

When changing the spark plugs, always ensure that the spark plug threaded portion of the shell (from the spark plug seat) is same length (or very close to) the O.E. spark plug. If the threaded portion is slightly longer, spark plug indexing washers can be used to obtain the desired spark plug reach.

The dense A/F mixture is much harder for spark to penetrate, and require much higher voltage (pressure). Higher fuel concentration has the same effect (lower A/F ratio).

How does a spark plug work in a Nissan?

Each spark plug works hard to kindle the air-fuel mix in the combustion chamber which drives your automobile. Your typical Nissan spark plug generates an electrical spark over a set gap on your plug, and once that happens, the delta is complete, so the boom can happen within your engine.

How big is the spark plug gap on a Promod Turbo?

Some applications such as ProMod turbo cars using M1 fuel frequently run a spark plug gap as small as .012″, even though they are equipped with some of the highest output ignition systems providing in excess of 60,000 Volts high current and high mJ power output.

What are the spark plugs on a Saturn?

The Saturn car has four spark plugs, one for each cylinder. Unlike other vehicles, however, the Saturn car uses a coil-on-plug setup instead of spark plug wires, where each spark plug has a separate ignition coil that amps up the battery voltage to the necessary power required to fire the spark plug.

Why are spark plugs so hard to fire?

Used spark plugs are hard to fire as the gaps are worn out, and insulation properties of the ceramic is compromised by solid combustion deposits and old fuel saturation. This robs available voltage at the spark plug gap, as it “leaks” through the low resistance carbon deposits to the ground, resulting in a weak spark.

How does the potential of a spark relate to the spark plug?

1) Potential of the ignition system – Spark Voltage (sometimes explained as Voltage potential or electrical pressure) corresponds with the distance that spark can cross at given air pressure and enviroment (concentration of the A/F (Air/Fuel) mixture etc… between the spark plug gap (center electrode and ground electrode).
