How Often Should You Really Replace Your Car’s Spark Plugs?
Spark plugs are essential for gas-powered cars as they begin the combustion process to start the vehicle. However, many people don’t think about replacing them regularly.
While there isn’t a universal number of miles driven before needing to change your spark plugs, the general rule of thumb is at least every 100,000 miles.
Each manufacturer differs and recommends different miles, so it’s best to consult your owner’s manual to see how often your car’s make and model needs new plugs.
There are several signs your spark plugs need changing, such as the check engine light coming on, difficulties starting your car, and having to fill up on gas more often.
