Oh, spark plugs. They’re the one car part everyone seems to have heard of. And that’s for good reason. If your engine is giving you trouble, one of the common reasons (and easy fixes) is the spark plugs. And since engine work can be out-of-this-world expensive, swapping out a $15 to $30 spark plug is a small price to pay for avoiding major engine overhaul. Replacing the engine could run you anywhere from $3,000 to $7,000!
Check and change the spark plugs about every 30,000 miles.
