When to Replace Spark Plugs in a Subaru Impreza
The service interval for replacing spark plugs in a Subaru Impreza is typically 60,000 miles or 60 months (5 years). This means that if your car hasn’t reached 60,000 miles, the spark plugs should generally be fine, as they don’t see significant wear if the car is not running. However, it’s important to note that the time-based service interval for spark plugs may still be relevant, especially if the car is not being driven frequently.
It’s also worth considering that even if only one spark plug has gone bad, it’s recommended to replace all of them at once. This is because if one plug has gone bad, the others aren’t far behind, and replacing all of them at once is more cost and labor efficient.
In summary, for a Subaru Impreza, it’s generally advisable to replace the spark plugs at the 60,000-mile mark or after 5 years, whichever comes first. However, if the car is not being driven frequently, it’s still important to consider the time-based service interval for the spark plugs.
