What Is Spark Plugs For Mercury Grand Marquis

What Is Spark Plugs For Mercury Grand Marquis

The spark plug is basically a part used in the engine to power up the performance and fuel economy. It sits above each cylinder head in the engine, ignites the air/fuel mixture, and starts the power stroke of the engine. An engine has one spark plug per cylinder used on the cylinder head.

A spark plug does not actually touch the air/fuel mixture; instead, the electrical sparks travel a small gap to initiate the combustion. And the force of this mini-explosion drives the piston down and creates power in the engine. Then the spark plug repeats this process over to run the Mercury Grand Marquis.

How To Read Spark Plugs For Tuning

How To Read Spark Plugs For Tuning

To read spark plugs for tuning, you do not have to be a professional mechanic. But it is also not that effortless either. To read them, you need to know what the sign means specifically.

Normal Condition: You can judge an engine’s condition by the appearance of the spark plug’s firing end. The brown or light grey color in the firing end of the spark plugs tells you that it is operating at optimum temperature and the engine is in good condition.

Dry & Wet Fouling: Suppose the firing end of the spark plug is fouled by either dry or wet carbon, which means the insulation resistance between the center electrode and the spark plug shell drops to 0 ohms. When the insulation resistance is over 10 ohms, the engine can start normally,

Over Heating: When a spark plug overheats, the deposits that have accumulated on the insulator tip get melted. So, a glossy and glazed insulator tip indicates the overheating spark plugs.

Deposits: If you notice the accumulation of deposits on the firing end, it is because of oil leakage. So, the deposit in the spark plug firing end indicates the oil leakage problem in the spark plug.

Lead FoulingP: Lead fouling usually appears as yellowish-brown deposits in the insulator nose. But you can not detect this by a resistance tester at room temperature because these lead compounds combine at different temperatures.

Lead Erosion: Lead erosion is happened due to the lead compounds in gasoline. When the compound reacts with the electrodes, erosion creates. So, lead erosion causes the surface of the electrode to be thinner, and the tip of the electrode looks chipped.

The spark plugs will give you the sign to understand if the spark plugs are in good condition or not. You have to read the spark plugs and replace them before they wear out.

Frequently Asked Question & Answer

1. What does a hot spark plug do?

Ans: A hot spark plug helps to prevent heat transfer in the water jackets. The insulator of a hot spark plug keeps more heat in the tip of the spark plug, which helps to burn off combustion chamber deposits.

2. Which spark plug is better? Iridium or Platinum?

Ans: Iridium spark plugs are more strong and hard than platinum spark plugs. It has a higher melting point compared to a platinum spark plug. Also, the iridium spark plug wears less.

3. How do I know if I need a hotter spark plug?

Ans: You can figure out whether you need a hotter spark plug or not by looking at the current ones. If the current spark plug is too hot, then the tip of the plug may be melted. Or, if the plug is too cold, then the plug may have excessive build-up.

4. Do iridium spark plugs increase horsepower?

Ans: Yes, iridium spark plugs take less voltage to fire, which results in more coil dwell time. And that translates to a better combustion chamber, lower emissions, and better fuel economy. That’s how iridium spark plugs increase the engine horsepower.

5. Which are the best spark plugs for Ford Crown Victoria?
