Frequently Asked Questions

What year did Ford 5.4 have spark plug problems blowing out?

The Ford 5.4 liter engine has experienced problems with its spark plugs since it was first introduced in 2004. The design of the spark plug, combined with the high compression ratio of the engine, can cause the spark plug to blow out under certain conditions. While this is not a common problem, it can be a serious one, and it has been known to occur in a number of different years.

In most cases, the problem will occur when the engine is under heavy load or when it is being revved up to high speeds. If a spark plug does blow out, it can damage the engine and cause expensive repairs to be necessary.

Which brand of spark plug is best?

There are a lot of different factors to consider when choosing the best brand of spark plug for your car. Some of the most important factors include the type of engine you have, the climate you live in, and your driving habits. In general, newer cars with fuel-injected engines tend to do well with platinum or iridium spark plugs.

These types of plugs last longer and don't require as much maintenance as older style plugs. If you live in an area with a lot of cold weather, it's also a good idea to choose a plug that's designed for cold starts. For example, NGK makes a line of "V" power plugs that are specifically designed for frigid temperatures.

finally, if you're someone who regularly drives long distances or tends to go hard on the gas pedal, it's worth opting for a high-performance spark plug like those made by Bosch or Denso. These plugs can handle more heat and stress without wearing out as quickly.

What type of spark plug is best for performance?

The type of spark plug that is best for performance depends on the make and model of the vehicle as well as the driving conditions. Some factors to consider when choosing a spark plug include: firing order, heat range, electrode material, and gap width. For example, iridium plugs are good for high performance engines because they have a smaller tip which helps to create a more efficient spark.

Platinum plugs are also good for high performance engines because they last longer and help to prevent fouling. The firing order is the sequence in which the cylinders fire. The order in which the cylinders fire affects how much power is delivered to the wheels.

A change in firing order can increase or decrease power depending on how it is done. The heat range of a spark plug is the measure of how hot or cold it burns. The higher the number, the hotter it burns.

Choosing a heat range that is too hot can cause pre-ignition and engine damage, while choosing one that is too cold can cause fouling and decreased engine performance. Electrode material also plays a role in spark plug performance. Copper has low electrical resistance and conducts electricity well, but it wears out quickly.

Platinum lasts longer than copper but does not conduct electricity as well as copper does. Iridium has excellent electrical conductivity and wear resistance properties, making it ideal for high performance applications. Finally, gap width also affects spark plug performance.

A wider gap means there is more air available for combustion, which can lead to increased power output from the engine.

Which is better iridium or copper spark plugs?

Iridium spark plugs are better than copper spark plugs for a few reasons. First, iridium is more durable and less likely to wear down over time. Second, iridium has a higher melting point, so it can withstand higher temperatures without breaking down.

Third, iridium produces a smaller spark than copper, which means that it is less likely to cause engine knock. Finally, iridium plugs are less likely to fouling than copper plugs.
