What is the original spark plug model for GAC Trumpchi GS4?
2 Answers
Trumpchi GS4 uses NGK brand iridium spark plugs with the model number 454523. The benefits of replacing spark plugs include improved vehicle performance. Spark plugs are consumable parts that require regular replacement. If spark plugs are damaged, they can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, reduced power, and most notably, difficulty in starting the engine, affecting normal vehicle use. Severe spark plug erosion, such as scarring at the top, damage, or melted electrodes, indicates that the spark plug is damaged and should be replaced. Spark plug location: Spark plugs are installed on the side or top of the engine. In earlier models, spark plugs were connected to the distributor via ignition cables. Over the past decade, most car engines have switched to direct connection between the ignition coil and the spark plug. Spark plug replacement interval: Under normal maintenance conditions, spark plugs should be replaced every 40,000 to 60,000 kilometers. However, this may vary depending on the brand and engine type, so it's recommended to follow the user manual. Generally, platinum spark plugs should be replaced every 40,000 kilometers, ordinary nickel alloy spark plugs every 20,000 kilometers, and iridium spark plugs every 60,000 to 80,000 kilometers.
I've been researching cars for many years and often help friends with car repairs. The original spark plugs for the GAC Trumpchi GS4 are typically the NGK LFR5AIX-Iridium model, suitable for the 1.5T engine. This model features a unique design with iridium electrodes that are heat-resistant and provide strong ignition, improving fuel efficiency and power response. The recommended replacement interval is between 30,000 to 60,000 kilometers, depending on driving habits. I've encountered many car owners who experienced issues after switching to non-original spark plugs, such as engine shaking or a significant increase in fuel consumption, so sticking to original parts is crucial. When replacing them yourself, pay attention to the spark plug gap and torque—specialized tools are very helpful. Regularly check the spark plug color—white indicates overheating, while black suggests incomplete combustion. Replacing them in time can prevent major engine overhauls. Always choose genuine parts, such as purchasing through official channels, and don't try to save small amounts of money at the risk of bigger losses.
