What are the effects of using incorrect spark plug models?

The effects of using incorrect spark plug models include: in mild cases, engine knocking or failure to start, and in severe cases, engine damage, unstable engine speed, or lack of power while driving. Spark plugs, commonly known as sparkers, function by discharging the high-voltage pulses delivered by the ignition cables (sparker wires), breaking down the air between the two electrodes to generate an electric spark, which ignites the air-fuel mixture in the cylinder. The main types of spark plugs include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Spark plugs work in conjunction with the ignition system and fuel supply system to enable the engine to perform work, and they significantly influence the engine's performance collectively.
I once changed spark plugs without paying attention to the model number, bought cheap ones and installed them. It turned out to be a disaster. The ignition was always rough, the engine shook like it was drunk, especially noticeable at low speeds. I had to floor the gas pedal just to get moving, and fuel consumption skyrocketed by 20%, costing me an extra hundred bucks a month on gas. After inspection, it was found that the spark plugs' heat range didn't match, and the combustion chamber was full of black carbon deposits, which also affected the catalytic converter's efficiency. The mechanic said if I hadn't dealt with it early, the engine would have needed a major overhaul. Now I strictly buy parts according to the manual's specifications, and the car runs much smoother, saving both money and hassle. The lesson is that details determine success or failure—never cut corners to save a few bucks.
