How often do I have to change the spark plugs

It goes without mentioning it, that as any other part of your vehicle some day spark plugs will be worn out and lose their features. Luckily, they don’t need to be replaced very often and can be used for many years and miles.

In general, it’d be better if you get a new spark plug installed after every 30 000 miles, however, it depends on the material, which was used for a spark plug production. Thus, iridium ones last the longest – up to 100 000 miles. By the time spark plugs get really worn out, it has withstood extremely high temperature and that’s the reason why the material plays such a crucial role.

To increase the lifetime of the spark plug, Bosch Double Iridium spark plug, which is the best spark plug for 1999-2019 Honda Civic, includes a high content iridium centre electrode for better durability and a more consistent and powerful spark, which leads to better performance over a lifetime of the spark plug.

Most manufacturers use varying levels of iridium, which can decrease the life of the spark plug as well as the performance.

The thing is that no other spark plug on the market is completely laser welded. But Bosch Double Iridium spark plug utilizes laser welding on the ground electrode as well as 360 degree continuous laser welding on the center electrode. It increases durability. Continuous laser welding increases the durability of the plug.

NGK 2477 is the best spark plugs for Honda Civic 1992-2000. These spark plugs feature a special fine wire iridium center electrode and taper cut ground electrode for maximum ignite ability and performance.

These spark plugs still have a copper core electrode and the iridium is in the tip of the plug.

So, as we've said many times before, iridium is a very strong material and has a high melting point, which makes it perfect for the performance based application.

The core and the iridium tip are going to be the determining factors of the heat range of the plug.

The idea behind fine wire spark plugs is to open up more area for flame expansion by reducing the mass of the center and ground electrodes. As the plug fires to ignite the air and fuel mix, there's more available area for flame expansion providing quicker starts, improved performance and better efficiency.

Additionally, this is going to feature some trivalent metal plating to ensure that this is not going to corrode and it's going to give you a long-lasting life.

Key features:

  • Iridium
  • Iridium Tip for a Constant Stable Spark
  • Pack of 4

Best Spark Plugs For Honda Civic Buying Guide

Hot or cold – Type of a Spark Plug to Choose

Besides the material composition, spark plugs differ depending on the heat range

The length and diameter of the insulator tip surrounding the center electrode regulates a spark plug's heat extent. This will influence how hot or cold the plug's tip operates.

A spark plug of a hot type will work at the highest temperatures (up to 850 C degree), which means they will rebuff the carbon deposits much better and efficiently. Thus, most cars, which are designed to be used in urban areas and city traffic, will have hot-type spark plugs.

However, the vehicles that are used for highway most of the time and which have really heavy loads, need cold-type spark plugs. They deplete heat faster and don’t let the engine get overheated as well as prevent pre-ignition.

Causes of spark plug fouling

A spark plug is like a canary in a coal mine for your engine. On the porcelain and electrodes it shows a lot of what's going on inside the engine.

There are three things that can foul a spark plug:

Too rich of a fuel mixture

Too rich of a fuel mixture on the electron or the spark plug will show up as a gray to matte black finish, that will be evenly distributed over the spark plug electrode and the porcelain. This is because there's too much fuel in the cylinder. A lot of the carbon that's left over gets on to the hot parts of the plug and sticks.

If you see a plug like this, there are a couple of things you need to look into. Look at the long term and short term fuel numbers to see what the engine’s doing. Look at the state of the injectors, it could be a clogged injector or an injector that's stuck open causing this condition.

Engine oil leak

Engine oil on a spark plug will have a black finish, but in some cases it's going to be a shiny black finish and it's not going to look the same as carbon deposits from fuel. It will be blotchy and inconsistent and may build up more in some of the colder areas of the spark plug.

Oil fouling might be caused by the positive crankcase ventilation system or an out rings or other things that can allow crankcase vapors and oil droplets into the combustion chamber, so make sure you diagnose this problem before you put the new plugs in.

Coolant

A leaking head gasket intake manifold gasket or other things on the vehicle that allow coolant to get into the combustion chamber can stick to the plug itself and cause it to foul. This will be a gray ashy appearance and may change a little bit, depending on the type of coolant that's in the vehicle.

Before you put new plugs in make sure you pressure test the system and diagnose all head gasket leaks.

So, oil, coolant or gas - these are the three things that can contaminate a spark plug, so make sure that you resolve those issues with that engine before you put new plugs in the vehicle. If not that canary in the coalmine may not be breathing too well.

Conclusion

To sum up, you can see that there are three main types of spark plugs – copper, platinum and iridium. Regarding all the expertise provided in the article, we can highly recommend to choose the iridium ones, bearing in mind that iridium plugs can remain in service up to 100 000 miles, while platinum ones – only up to 60 000 miles and copper ones – up to 25 000 miles.

So you can see how important the material of your spark plug is in terms of its longevity. Don’t forget that they should be replaced regularly, otherwise your vehicle will get really low supply of energy and won’t benefit from it at all. So keep up to all the recommendations listed above and you’ll never have any troubles!
