You can reduce the cost to replace spark plugs by doing this job yourself. Your exact replacement cost will also depend on how many spark plugs are needed (typically between 4 and 16) and whether you choose long-life platinum-tipped spark plugs or cheaper conventional ones.
Keep in mind: There are many different types of spark plugs, and not all plugs fit all vehicles. If you plan to replace your spark plugs yourself, be sure to choose the right parts to fit your vehicle. When in doubt, always consult your owner’s manual, or follow our comprehensive guide on how to replace your spark plugs at home.
What Are Spark Plugs?
Brand new spark plug (left) versus old, worn out spark plug (right).
Spark plugs are as important to your engine as the gasoline in your tank. As the name suggests, the spark plug creates a spark in the combustion chamber to ignite the air/fuel mixture, which drives your engine. Most engines feature one spark plug per cylinder, but some newer, more advanced engines feature two spark plugs per cylinder. It is extremely important that your vehicle’s spark plugs are functioning properly to maximize reliability and fuel efficiency, so be sure to replace spark plugs regularly.
How To Replace Spark Plugs?
The spark plug screws into the cylinder and head, and they are connected using either plug wires or coil packs. Knowing how to replace spark plugs is basically the same across all types of engines, but this job tends to be easier on vehicles equipped with an inline engine rather than wider V-6 or V-8 engines.
The spark plugs on a 1997-2006 Jeep Wrangler are super easy to change out, but that isn’t the case with all cars/engines.
What Happens If You Don’t Replace Spark Plugs?
Only in the most absolute worst-case scenario would an old spark plug create a safety issue or cause damage to your engine, but worn out spark plugs will definitely affect the performance of your engine. If you don’t replace the spark plugs at the recommended intervals, you’re most likely going to suffer from a rougher idle and reduced fuel economy, but waiting too long could result in reduced reliability and even being stranded on the side of the road.
How Often Should You Replace Spark Plugs?
Most automakers recommend replacing the spark plugs every 30,000 miles or so, but be sure to check your owner’s manual or use the free FIXD app for accurate maintenance schedules. Replacing spark plugs can definitely be an easy DIY repair, but it all depends on the specific vehicle and engine type.
