Summary: Learn about the role of spark plugs in your Subaru Forester’s ignition process and why they need to be replaced over time.
Spark plugs are small, but they play a crucial role in the overall functioning of your Subaru Forester’s engine.
They are responsible for generating the electric spark that ignites the air-fuel mixture in the combustion chamber, resulting in the controlled explosion that powers your vehicle. Without functioning spark plugs, your engine simply wouldn’t start.
Over time, spark plugs can become worn out and less effective. This is primarily due to the constant exposure to high temperatures, electrical currents, and chemical reactions that occur during the combustion process.
As a result, the electrodes, which are the small metal tips at the end of the spark plugs, can wear down, become eroded, or get covered in carbon deposits.
When this happens, the spark plugs are less efficient at generating the necessary spark, leading to various performance issues in your Subaru Forester.
Replacing spark plugs at regular intervals is essential to maintain optimal engine performance. By installing new spark plugs, you ensure that the ignition system is working at its best, resulting in smoother starts, improved fuel efficiency, and better overall engine performance.
Neglecting spark plug replacement can lead to decreased power, reduced fuel economy, increased emissions, and even engine misfires.
How often should spark plugs be replaced?
Summary: Understand the recommended intervals for spark plug replacement in a Subaru Forester and the factors that can impact their lifespan.
The recommended interval for spark plug replacement in a Subaru Forester is typically around every 60,000 to 100,000 miles, or every 5 to 7 years. However, it’s important to note that this can vary depending on several factors, including the type of spark plugs installed, driving conditions, and the specific model year of your Subaru Forester.
Some newer models may have platinum or iridium-tipped spark plugs, which are designed to last longer than traditional copper-tipped plugs.
These high-performance spark plugs can often reach 100,000 miles or more before replacement is necessary.
However, it’s always best to consult your vehicle’s owner’s manual or speak with a trusted mechanic to determine the specific replacement interval for your Subaru Forester’s spark plugs.
Additionally, certain driving conditions can accelerate spark plug wear and necessitate more frequent replacement.

While following the recommended replacement interval is crucial, there are several signs that can indicate your Subaru Forester’s spark plugs are due for replacement before reaching the specified mileage or time threshold. Being aware of these signs will help you address any spark plug issues promptly and prevent further damage to your vehicle.
1. Rough idling:
If you notice that your Subaru Forester’s engine is running inconsistently or vibrating more than usual while at idle, this could be a sign of worn-out spark plugs.
As the spark plugs deteriorate, they may struggle to generate a consistent spark, causing the engine to misfire or run unevenly at idle.
2. Difficulty starting the engine:
If you find that your Subaru Forester is becoming increasingly difficult to start, particularly on cold mornings or after the vehicle has been sitting for an extended period, it could indicate that your spark plugs are nearing the end of their lifespan.
Faulty or worn-out spark plugs may not provide the necessary spark to ignite the air-fuel mixture, making it harder for the engine to start.
3. Reduced fuel efficiency:
Spark plugs that are nearing the end of their lifespan can lead to decreased fuel efficiency in your Subaru Forester.
As the spark plugs become less effective, they may not ignite the air-fuel mixture as efficiently, resulting in incomplete combustion and wasted fuel.
If you notice a sudden drop in your vehicle’s fuel economy, it’s worth considering a spark plug replacement.
4. Engine misfires:
One of the most noticeable signs of worn-out spark plugs is engine misfires. Misfires occur when the spark plugs fail to generate a spark or produce a weak spark, resulting in incomplete combustion in one or more cylinders.
This can lead to a variety of symptoms, such as a rough-running engine, loss of power, hesitations, or even the illumination of the check engine light. If you experience any of these issues, it’s crucial to have your spark plugs inspected and replaced if necessary.
5. Poor acceleration and sluggish performance:
Worn-out spark plugs can significantly impact your Subaru Forester’s acceleration and overall performance.
If you notice a decrease in power when accelerating, a lack of responsiveness, or a general sluggishness in your vehicle’s performance, it may be time for a spark plug replacement.
DIY vs. Professional spark plug replacement: Which is right for you?
