One of the most important aspects of vehicle maintenance is ensuring your spark plugs are in good working order. There’s a likely probability you will need to replace your old spark plugs several times over the course of owning a 2009 Kia Sportage. Spark plugs are one of the most important parts 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 components, spark plugs experience wear over time and eventually need replacement, 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 maybe 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 roughly 20-45 minutes. This article will go over everything you will need to know about your Kia Sportage’s spark plugs, whether you need some baseline information or a full, step-by-step guide to performing a spark plug change.

NGK 5464[/caption]For any 2009 Kia Sportage, you can use NGK 5464 spark plugs. These will be an exact fit and will match the required specifications of your engine. Make sure you purchase the correct quantity of spark plugs for your engine corresponding to the number of cylinders. Sometimes manufacturers will bundle spark plugs in quantities that make it nearly impossible to buy the exact amount you need for your engine. In this case, it is not a bad idea to purchase enough for your next two spark plug changes just so you will always have a new set ready. 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?
In general, 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 specific interval determined by Kia for the 2009 Sportage. Of course, if you drive your vehicle more aggressively or own a Sportage 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 telltale signs of a car that may potentially need a spark plug replacement prematurely, 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 solitary culprit. However, the best way to prevent any issues with your vehicle is to take care of it with routine maintenance, and you are definitely doing so with the responsible decision to replace your Kia Sportage’s spark plugs on a regular basis.
Changing spark plugs on a 2009 Kia Sportage
This is a process you should be able to do on your own with some commonplace garage tools. Of course, consult your owner’s manual, as well as a factory service manual (FSM) or an equivalent Haynes or Chiltons manual. The video shown below does a good job of outlining the process.
As noted before, you should be able to do a spark plug change with some ordinary tools you likely 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 definitely 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 something going wrong. This tool can help you diagnose the definite problem.
- A set of spark plug sockets – These come in extremely handy because many standard sockets are not deep enough for spark plugs. Additionally, 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 very important tool to have in your collection. You will want to check your factory service manual to determine the correct torque rating to use when putting in the new spark plugs for your 2009 Kia Sportage to be confident 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 this is not the case, you should absolutely have one of these.
- I also highly recommend you have a feeler gauge as it makes it a bit more straightforward to check the exact gap, and it is useful for quite a few other jobs.
Tips for changing spark plugs on your 2009 Kia Sportage
Ensure you watch the video above before you attempt to repair the spark plugs on your 2009 Kia Sportage, as well as review your factory service manual. Additionally, we have some tips below here to help you as you complete this repair.
- 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 2009 Kia Sportage
- You might consider using dielectric grease when installing new spark plugs. You can apply a a small dab to the inside of the boot and the ceramic part of your spark plugs. It lessens the chance of voltage leak and helps avoid the misfortune of the boot fusing to the spark plug over time.
- Before starting, disconnect the negative terminal of your battery. It’s a good idea to disconnect the battery anytime you work on the electrical system of your Kia Sportage or any other vehicle.
- 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 light coating 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.
