Socket Size for Subaru Spark Plugs
When it comes to the socket size for Subaru spark plugs, the most commonly recommended size is a 14mm spark plug socket. This size is often mentioned across various Subaru forums and discussions as the preferred socket size for the task .
It’s important to use the proper size socket to avoid the risk of ’rounding off’ the spark plug hex’s with the wrong size wrench, as mentioned in one of the sources. Additionally, it’s advised to be cautious about applying too much torque or leverage, as this could potentially damage the threads or break the spark plug while it’s still in the engine.
In some cases, there may be variations in the socket size based on the specific Subaru model and year. For instance, it’s noted that Subaru has switched to a thin wall 14mm spark plug socket on certain models from 2014 onwards. Therefore, it’s always a good idea to verify the specific socket size recommended for your particular Subaru model and year.
Overall, the general consensus across the sources is that a 14mm spark plug socket is the most commonly used and recommended size for Subaru spark plugs.
