To replace spark plugs in a Chevy Malibu, the cost can vary depending on several factors. The number of spark plugs that need to be replaced, the accessibility of the spark plugs, and the amount of diagnosis required can all affect the cost. If the spark plugs are easy to access, it is usually a simple repair. However, if the spark plugs are hidden and require a lot of disassembly, it may be better to have a repair facility handle the job. The cost can range from surprisingly low to very high.
It’s important to note that in some cases, other components like valve cover gaskets, ignition cables (spark plug wires), or coils may need to be replaced along with the spark plugs, which can add to the overall repair cost [[4]] .
If you choose to replace the spark plugs yourself, make sure to have the proper spark plug gap, use anti-seize compound on the threads, use dielectric grease on the spark plug terminal, and ensure the threads go in straight before attempting the replacement.
It’s worth mentioning that spark plug replacement is a maintenance item that should be completed about every 30,000 miles or as specified by your owner’s manual. Regularly replacing spark plugs is important for maximizing reliability and fuel efficiency.
Please keep in mind that the specific cost for spark plug replacement in a Chevy Malibu can vary depending on the location, the repair facility, and any additional repairs or parts that may be needed. It’s always a good idea to get a quote from a reputable repair facility or mechanic to get an accurate estimate for your specific situation.

How long do Chevy spark plugs last?
every 30,000 miles
Not only should you consider replacing your spark plugs every 30,000 miles, but you should also consider doing so when you experience: Rough idling. Slow or no start. Engine misfiring.
Will bad spark plugs throw a code?
Often, there’s an odor of unburnt gasoline that will be noticeable whenever a spark plug goes bad. On a new enough vehicle, you’ll likely also see a check engine light. That light will most likely be throwing a code for an engine misfire on one cylinder.
What causes bad spark plugs?
Overheating. Repeated overheating of the spark plug tip can cause the plug to prematurely fail. Overheating can be caused by many things like pre-ignition and a malfunctioning cooling system. Pre-ignition can lead to heat building up in the combustion chamber causing the spark plugs to fail.
Can I change spark plugs myself?
Replacing worn spark plugs can greatly improve your engine’s performance and efficiency, and it can be done at home with basic hand tools. Recommended spark plug replacement intervals can range from 30,000 miles to every 100,000 miles, and they vary widely by car manufacturer and spark plug metal types and design.
Why is replacing spark plugs so expensive?
High labor costs
After that’s removed, each of the eight ignition coils must be removed before the new plugs can replace the old ones. “Layers of the engine have to come off in order for them to get these parts,” Anderson explained. That’s why the labor charge is high, he said.
Can you drive with bad spark plugs?
Ideally, you should replace them immediately. However, you can get by for a short while, as long as they aren’t misfiring. Poor spark keeps fuel from being burned inside the combustion chamber. This reduces power and fuel economy, and it makes it harder for the engine to idle.
How much is labor for spark plugs?
Typically, the labor costs for a spark plug replacement are about $129 to $163. But whether it’s a good idea depends on your comfort level for DIY automotive projects and the type of car you have. On some models, spark plugs are easy to reach, but on other vehicles, they’re more difficult to access.
