I've changed the spark plugs on my Volkswagen Sagitar several times myself, and it feels like a simple DIY job. Just make sure the engine is fully cooled before starting to avoid burns. All you need is a spark plug socket wrench, which you can buy online for around 20 yuan. Open the engine hood and locate the ignition coils—they're right on top of the engine. Carefully unplug the coil wires, noting their order to avoid confusion. Use the wrench to unscrew the old spark plugs counterclockwise, being gentle to avoid damaging the holes. After removing them, check for carbon buildup or debris, and clean the area with a cotton swab dipped in alcohol. Buy new spark plugs that match your car's specifications—NGK or Bosch brands work well—and apply a bit of dielectric grease to the threads. Hand-tighten the new plugs a few turns first, then use the wrench to gently tighten until snug, but don't overtighten or risk breaking them. Reconnect the coil wires, start the car, and listen for smooth operation without odd noises—that means you're done. The tools are cheap, and doing it yourself saves hundreds in just half an hour. But if you're inexperienced, watch video tutorials first to avoid damaging parts. Regularly replacing spark plugs improves fuel efficiency and makes acceleration smoother.
