2015 WRX Spark Plug Socket Size
Overview
If you own a 2015 Subaru WRX and are looking to change the spark plugs yourself, it’s important to know the correct socket size to use. Using the wrong size socket can lead to damage to the spark plug or the socket itself. In this article, we will provide you with the necessary information to determine the spark plug socket size for your 2015 WRX.
Determining the Spark Plug Socket Size
To determine the spark plug socket size for your 2015 WRX, you can refer to the owner’s manual or consult the manufacturer’s specifications. However, if you don’t have access to these resources, you can also measure the spark plug hex size using a caliper or ruler.
Measuring the Spark Plug Hex Size
To measure the spark plug hex size, follow these steps:
- Ensure the engine is cool and the ignition is turned off.
- Locate the spark plugs on your 2015 WRX. They are typically located on the top of the engine, connected to the ignition coils.
- Remove one spark plug wire by firmly grasping the boot and pulling it straight off the spark plug.
- Using a spark plug socket and ratchet, carefully loosen and remove the spark plug from the engine.
- Inspect the spark plug hex, which is the six-sided portion at the top of the spark plug.
- Using a caliper or ruler, measure the distance across two opposite sides of the hex. This measurement will give you the spark plug socket size.
Spark Plug Socket Size Chart
Here is a table providing the spark plug socket size for different spark plug hex measurements:
| Spark Plug Hex Size (mm) | Socket Size (mm) | Socket Size (inches) |
|---|---|---|
| 14 mm | 16 mm | 5/8 inch |
| 16 mm | 18 mm | 11/16 inch |
| 18 mm | 20.8 mm | 13/16 inch |
Using the Correct Spark Plug Socket Size
Once you have determined the spark plug socket size for your 2015 WRX, it’s important to use the correct socket when removing or installing spark plugs. Using a socket that is too small or too large can result in damage to the spark plug or the socket itself.
- Ensure the socket is securely attached to the ratchet or extension.
- Carefully align the socket with the spark plug hex.
- Apply steady pressure while turning the socket counterclockwise to loosen the spark plug.
- Once the spark plug is loosened, continue turning it by hand until it can be removed easily.
- When installing new spark plugs, use the socket to tighten them securely, but avoid overtightening.
Conclusion
Knowing the correct spark plug socket size for your 2015 WRX is essential for proper maintenance and replacement of spark plugs. By following the steps outlined in this article and referring to the spark plug socket size chart, you can confidently perform this task yourself. Remember to always use the correct socket size to avoid any potential damage.
