What is the replacement interval for Accord spark plugs?
2 Answers
The replacement interval for Accord spark plugs is 60,000 kilometers. The spark plug models are NGK IZFR6K11NS and Bosch FR6LII330X. Taking the 2018 Accord as an example, it belongs to the mid-size car category with body dimensions of 4893mm in length, 1862mm in width, and 1449mm in height, with a wheelbase of 2830mm and a curb weight of 1548kg. The 2018 Accord features a MacPherson strut front suspension and a multi-link rear suspension. It is equipped with a 2.0L naturally aspirated engine producing a maximum horsepower of 146PS, maximum power of 107kW, and maximum torque of 175Nm, paired with an electronic continuously variable transmission.
I've been driving an Accord for several years, and the spark plug replacement interval depends on the model year and driving habits. Generally, the manual recommends changing them every 60,000 to 80,000 kilometers, or roughly every 4 to 5 years. For example, my 2018 model had its spark plugs replaced at 70,000 kilometers, which worked out well. At the time, I noticed the car was sluggish during acceleration and fuel consumption had spiked. Later, I realized that worn spark plugs can affect ignition, leading to engine misfires. During routine maintenance, it's a good idea to check the spark plug gap—don’t wait until a major issue arises. If you frequently drive in city traffic with heavy congestion, the wear can be faster. I find that replacing them regularly saves hassle, and spending a bit more on genuine OEM parts is worth it, especially since the Accord’s engine has high compatibility requirements. In short, follow the official guidelines and consult a mechanic for advice before making any changes.
