2014 Kia Soul Spark Plug Replacement Guide

One of the most important aspects of vehicle maintenance is ensuring your spark plugs are in good working order. There’s a good chance you will need to replace your set of spark plugs several times during your ownership of a 2014 Kia Soul. Spark plugs are one of the most important components inside your engine as they start the entire combustion process that starts and keeps your engine running for many thousands of miles. Like most engine parts, spark plugs experience wear over time and eventually need to be swapped out for new replacements, but fortunately this is a repair you can do yourself. Chances are, if you’ve found yourself here, you have no idea how to do that, or potentially you’d just like to know what kind of spark plugs you need to buy. The entire process of changing your spark plugs should take approximately 20-45 minutes. This article will go over everything you should need to know about your Kia Soul’s spark plugs, whether you need some general information or a full, step-by-step guide to performing a spark plug change.

Correct spark plugs on a 2014 Kia Soul

CHAMPION 445[/caption]For any 2014 Kia Soul, you can use CHAMPION 445 spark plugs. These will be an exact fit and will match the required specifications of your engine. As this 2014 Kia Soul features a 4 cylinder engine, ensure you purchase 4 spark plugs. We always try to recommend the best possible spark plugs for the money, and these spark plugs are either a factory recomendation or an equivalent replacement available now at an affordable price.

How often should I change my spark plugs?

Very generally, it is advised that you replace spark plugs once every 20,000 to 40,000 miles. Of course, please make sure to check your owner’s manual to determine the exact interval determined by Kia for the 2014 Soul. Of course, if you drive your vehicle more aggressively or own a Soul with some modifications, you may want to consider changing your spark plugs closer to the 20,000 miles end of that spectrum.

However, there are also classic signs of a car that may need a spark plug replacement early, such as:

  • Rough idle
  • Engine misfiring
  • Problems starting your engine

As a quick note, keep in mind that this list is of course not comprehensive, and these problems on their own do not necessarily point to the spark plugs being the standalone culprit. However, the best way to prevent any issues with your vehicle is to take care of it with organized maintenance, and you are definitely doing so with the responsible decision to replace your Kia Soul’s spark plugs on a regular basis.

Changing spark plugs on a 2014 Kia Soul

This is a process you should be able to do on your own with some ordinary garage tools. Of course, consult your owner’s manual, as well as a factory service manual or an equivalent Haynes or Chiltons manual. The video shown below does a good job of outlining the process.

Helpful Tools

We recommend having a spark plug gap tool in your arsenal. It’s an inexpensive tool that will come in handy often.
As noted before, you should be able to do a spark plug change with some ordinary tools you probably already have. However, there are a few tools that are specific to this job that you may not have, and we also want to recommend some general tools that you should for sure have in your toolbox if you don’t already.

  • A spark plug tester – this is definitely a niche tool, but it can save you a ton of time. Although we’ve discussed spark plug replacement being a good thing to replace regularly and not just when issues occur, you may also be replacing your spark plugs because of a problem. This tool can help you diagnose the exact problem.
  • A set of spark plug sockets – These come in very handy because many standard sockets are not deep enough for spark plugs. Also, some spark plug holes are a bit smaller, so it requires a thinner wall like the one featured in the product here to fit. The linked product also features a magnet to keep a good hold of the spark plug so you do not drop it into your engine bay!
  • A torque wrench is a vital tool to have in your collection. You should check your FSM (factory service manual) or owner’s manual to determine the correct torque rating to use when putting in the new spark plugs for your 2014 Kia Soul to be certain they are installed properly.
  • A spark plug gap tool. This allows you to check the gap of your spark plugs and modify it if necessary. Most plugs will come pregapped, but if not, you should definitely have one of these.

Tips for changing spark plugs on your 2014 Kia Soul

It is a great idea to have some dielectric grease handy.
Be sure to reference the video above before you attempt to repair the spark plugs on your 2014 Kia Soul, as well as review your FSM (factory service manual) or owner’s manual. Be sure to check the tips shown here to help you as you perform this repair.

  • Before you begin, disconnect the negative terminal of your battery. It is wise to disconnect the battery anytime you work on the electrical system of your Kia Soul or any other vehicle.
  • You might consider using dielectric grease when installing new spark plugs. You can apply a a very light coating to the inside of the boot and the ceramic part of your spark plugs. It prevents voltage leak and helps avoid the misfortune of the boot fusing to the spark plug over time.
  • Note that this is not official advice as many spark plug manufacturers advise against the use of anti-seize. However, I have heard from numerous old-school mechanics that they always apply a small amount of anti-seize to the threads of their spark plugs, especially on older vehicles.
  • During this process, one of the most vital things to ensure you do is to avoid overtightening the plugs or worse, cracking them due to overtightenting. Use a torque wrench capable of lower, more precise torque ratings to be sure that you don’t make this mistake.
  • Your engine should be completely cold before you replace your spark plugs. Wait at least 30 minutes after your engine has been running before attempting to replace the spark plugs on your 2014 Kia Soul
