Spark plugs are an essential component of any vehicle’s engine, responsible for igniting the fuel and air mixture within the engine’s combustion chamber. As such, it’s important to ensure they are working correctly and replaced as needed. 

However, changing spark plugs can be a daunting task for many people, especially those without much experience working on cars. In this blog post, we’ll discuss some of the most common issues people face when changing spark plugs in their cars and how to address them.

How Often Should You Replace Spark Plugs Anyway?

The frequency at which you should change your spark plugs can vary depending on a few factors, such as the make and model of your vehicle, your driving habits, and the type of spark plugs you use. However, as a general guideline, it’s recommended to change your spark plugs every 30,000 to 100,000 miles.

If you have an older vehicle or if you frequently drive in stop-and-go traffic or harsh conditions, such as extreme temperatures or dusty environments, you may need to change your spark plugs more frequently. On the other hand, if you have a newer vehicle with iridium or platinum spark plugs, you may be able to go longer before needing to change them. Either way, make sure to use quality spark plugs from brands such as NGKBosch and others.

Ignoring spark plug replacement can lead to decreased engine performance, decreased fuel efficiency, and potential engine damage. So, it’s essential to stay on top of your vehicle’s maintenance needs and replace your spark plugs as needed.

Common Issues You Might Face When Replacing Your Spark Plugs

Spark plug replacement is one of those jobs that seems straightforward enough on paper. However, it can sometimes prove to be a major pain, turning a 20-minute project into a full day of work. Here are the most common issues you can face when replacing your spark plugs.

Difficulty Accessing the Spark Plugs

When changing spark plugs, accessing them can be challenging, especially if they’re located in hard-to-reach areas like under the engine cover or deep within the engine block. The situation can be aggravated if you don’t have the appropriate tools, such as a socket wrench with an extension, to help with removing and replacing them.

To overcome this challenge, it’s crucial to have the necessary tools, including removing any obstacles that may hinder accessing the spark plugs. You can also refer to your vehicle’s owner’s manual or online resources for guidance on how to access the spark plugs.

Incorrectly Gapped Spark Plugs

Incorrectly gapped spark plugs can also be a problem when replacing spark plugs, affecting engine performance, fuel consumption, and potentially causing engine damage. The gap refers to the distance between the center electrode and ground electrode of the spark plug, and it’s important to ensure this gap is correct for your vehicle’s engine.

To address this issue, check your vehicle’s owner’s manual or online resources to determine the correct spark plug gap for your engine. You can then use a feeler gauge to check and adjust the gap as needed.

Stripped or Stuck Spark Plugs

Stripped or stuck spark plugs can be a common problem when replacing spark plugs, usually when the spark plug threads are damaged or rusted, making them difficult to remove. It’s essential to avoid forcing them out, as it can cause further damage to the engine.

To handle this issue, use the appropriate socket wrench size and apply steady pressure when removing the spark plug. If the spark plug is stuck, apply a penetrating oil to loosen it. Avoid using too much force when removing the spark plug, as it can break off inside the engine.

Using the Wrong Type of Spark Plug

Using the wrong type of spark plug can lead to poor engine performance and potential engine damage. Spark plugs come in different types and heat ranges, and it’s essential to use the correct type of spark plug for your engine.

To avoid this issue, refer to your vehicle’s owner’s manual or online resources to determine the correct type and heat range of spark plug for your engine. You can then purchase spark plugs that meet these specifications.
