Where is the spark plug of the Mazda 3 Axela?

The location of the Mazda 3 Axela's spark plug: The spark plug is installed on the side or top of the engine. In earlier models, spark plugs were connected to the distributor via ignition cables. However, over the past decade, most car engines have been modified to have the ignition coil directly connected to the spark plug. How the spark plug works: The spark plug's ground electrode is connected to the metal shell, which is in turn connected to the engine block via the threads on the cylinder head. The insulator primarily serves to isolate the metal shell from the central electrode. The terminal nut is the part of the spark plug that contacts the high-voltage coil. When current passes through the terminal nut and the central electrode, it ionizes the medium between the central electrode and the ground electrode, generating a spark that ignites the air-fuel mixture in the cylinder.
I've been fixing cars myself, and when it comes to the spark plug location on the Mazda3 (Axela), it's actually not hard to find. After opening the hood, it's right on the cylinder head at the top of the engine, often covered by a plastic cover or shield that might have the Mazda logo printed on it. The position is slightly forward of center, and after removing this cover, you can see several small round holes where the spark plugs are inserted. Don't work on it when the engine is hot to avoid burns. Spark plugs affect the engine's ignition efficiency. If the car has weak acceleration or increased fuel consumption, it might be due to carbon buildup on the spark plugs. It's recommended to replace them every 20,000 kilometers. If you're doing it yourself, just use a socket wrench, but be gentle when unplugging the wires to avoid damaging the ignition coils. The design is quite user-friendly, requiring minimal disassembly, so even beginners can get the hang of it with practice. Remember to turn off the engine and engage the handbrake before starting—safety first.
I've been driving the Mazda3 (known as Axela in some markets) for many years, and the spark plug location is quite intuitive. Simply open the engine hood, and you'll find them positioned at the top, usually covered by a black protective cap. After removing the cover, you'll see the cylinder area where the spark plugs are secured in their designated holes. Located centrally towards the front, they're easy to spot. I always let the engine cool down for a few minutes after opening the hood before touching anything. Worn spark plugs can cause engine misfires or starting difficulties, so regular maintenance is crucial – I recommend checking them every 15,000 kilometers. Their accessible position allows me to often replace them myself using a dedicated spark plug socket wrench. Just ensure proper alignment when reinstalling, and avoid over-tightening to prevent damaging the threads.
