How to Replace Spark Plugs in a Bora?

[Jayce]

The method to replace spark plugs in a Bora is: 1. Remove the engine cover; 2. Disconnect the ignition coil wiring; 3. Use a flathead screwdriver to pry and remove the ignition coil; 4. Loosen the spark plug with a socket wrench; 5. Remove the old spark plug and install the new one. The Bora is a compact 4-door, 5-seat sedan with body dimensions of 4663mm in length, 1815mm in width, 1462mm in height, and a wheelbase of 2688mm. It is equipped with a 1.2T turbocharged engine and a 7-speed dual-clutch transmission, delivering a maximum power of 85 kW and a maximum torque of 200 Nm.

I just bought a Bora, and after driving tens of thousands of kilometers, I always felt the acceleration was sluggish. After checking the information, I found that the spark plugs needed to be replaced. The tools I prepared included a 16mm spark plug wrench, new spark plugs, gloves, and a torque wrench, ensuring the model matched the original iridium type. The first step of the process was to disconnect the negative battery terminal to prevent electric shock—safety first! Then, I removed the ignition coils one by one, loosened the old spark plugs, cleaned the surrounding oil stains after removal, and adjusted the gap of the new spark plugs to around 0.7mm before installation. I slowly tightened them and used the torque wrench set to the manufacturer-recommended 25 N·m. After reinstalling the ignition coils, I started the engine for a test. The engine vibration was reduced, and the driving became much smoother. DIY saved me a hundred yuan, but I recommend beginners to search for video tutorials on Xiaohongshu first.

Having changed quite a few Bora's spark plugs, here's my straightforward advice. A spark plug socket, gloves, and a wrench are all the tools you need—keep it simple. After disconnecting the battery, remove the ignition coils, and when taking out the old spark plugs, be gentle to avoid damaging the threads. Hand-tighten the new spark plugs first, then give them just half a turn more—over-torquing can damage the cylinder head. After installation, test the car; smooth idling is key. Regular replacement every 30,000 km saves fuel and boosts power—I've seen too many carbon buildup issues affecting fuel efficiency. The whole process takes about half an hour, so don’t delay to avoid triggering the check engine light.

As an automotive technology enthusiast, changing the spark plugs for a Bora requires attention to detail. First, select the correct model such as NGK or Bosch, ensuring the gap is accurate, adjusted to 0.7mm using a gap gauge. Disconnect the battery's negative terminal, remove the ignition coil screws, and carefully extract the old spark plugs. Before installing new spark plugs, apply a small amount of anti-seize compound to prevent sticking, then use a torque wrench to precisely control the torque to 20-30 Nm. After testing, the engine ignites more powerfully. The entire operation should be performed in a clean environment to prevent dust from entering the cylinders. For spark plug materials, platinum or iridium is preferred, as they extend lifespan and reduce emissions.
