How often should the spark plugs be replaced on a Hyundai Elantra?

Hyundai Elantra spark plugs should be replaced approximately every 40,000 kilometers. The working principle of spark plugs is to introduce high-voltage current from the gasoline engine's ignition system into the cylinder to generate an electric spark, which ignites the combustible gas mixture. The Elantra is a compact car produced by Beijing Hyundai. Taking the 2020 Elantra Manual Zhixuan Huoli model as an example, its body dimensions are: length 4610 mm, width 1800 mm, height 1450 mm, with a wheelbase of 2700 mm. The 2020 Elantra Manual Zhixuan Huoli model is equipped with a 1.5L naturally aspirated engine, with a maximum power speed of 6300 revolutions per minute and a maximum torque speed of 4500 revolutions per minute.

I've been driving the Hyundai Elantra for almost four years. The manual recommends replacing the spark plugs every 60,000 kilometers or 4 years, but in reality, with frequent traffic jams in the city, it's advisable to check them every 40,000 kilometers. I replaced mine at 50,000 kilometers last time and noticed much smoother ignition and a slight drop in fuel consumption. I recommend using iridium spark plugs—they're more expensive but last longer, easily up to 70,000-80,000 kilometers. Pay attention to the engine's startup sound; if it becomes rough or you notice minor vibrations, get it checked at a repair shop immediately to avoid major issues. DIY replacement can be tricky, so it's best left to professionals who can also clean carbon deposits, ensuring long-term stability for your car.

As a seasoned driver with over 20 years of experience, I believe spark plug replacement should be based on symptoms. For cars like the Elantra, the general recommendation is to replace them every 40,000 to 60,000 kilometers. However, if you notice sudden increases in fuel consumption, sluggish acceleration, or difficulty starting the engine, it's time for an early inspection. I make it a habit to have a technician briefly check the spark plugs every 30,000 kilometers. If there's significant carbon buildup, I address it promptly to avoid affecting engine performance. Remember, don't delay—early replacement can save you from costly engine overhauls later and give you greater peace of mind while driving.

Having worked on the Lingdong vehicle maintenance for years, common spark plug issues stem from carbon buildup or wear. The standard replacement interval is 40,000 kilometers, or as recommended in the owner's manual with an initial inspection every 4 years. Symptoms like increased fuel consumption or noticeable engine shaking indicate it's time to act. During routine maintenance, have technicians test them with tools—it's efficient and accurate.
