Does Changing Spark Plugs Make a Difference? In my opinion, changing spark plugs and wires is an excellent idea if your car has over 100k miles. My 2007 Chevy Impala LTZ has 110k miles, and it made a huge difference. Have you had a similar experience? Let me know! Also, feel free to recommend more video ideas in the comments. Thanks!
