There are many well-known brands of spark plugs in the market, and the prices are different. Many riders are curious about which brand of spark plug has the best performance.

The office environment of spark plug is extremely extreme, so it must be disassembled and replaced regularly, but the more expensive the spark plug, the higher the price. When choosing a spark plug for your car, you must pay attention to choosing the one that matches the vehicle. The selection of spark plugs is usually based on the engine compression ratio of automobile engines. The greater the compression ratio of the engine, the higher the spark plug with high calorific value, and conversely, the spark plug with low calorific value. Try to choose the same calorific value as the original spark plug, and it is best not to disassemble and replace it at will.
