What is the brand of BMW spark plugs?
2 Answers
BMW spark plugs are manufactured by Bosch. The functions of spark plugs are: 1. To introduce the high-voltage electricity generated by the ignition coil into the engine cylinder; 2. To generate sparks between the spark plug electrode gaps to ignite the air-fuel mixture, ensuring the engine operates normally. BMW models include: BMW X3, BMW 5 Series, BMW X5, BMW M2, BMW M8, etc. Taking the 2020 BMW M8 as an example, it belongs to the full-size car category with body dimensions of: length 5104mm, width 1943mm, height 1420mm, wheelbase 3027mm, fuel tank capacity 68L, and trunk capacity 440L.
I often repair BMWs, and to be honest about spark plug brands, BMW usually uses Bosch or NGK when they leave the factory. From my experience, older 3 Series models mostly come with Bosch FR7DC+, while some newer ones use NGK Iridium. Spark plugs are crucial as they directly affect engine ignition efficiency. I've helped many owners with inspections—if not replaced on time, the car may shake or even consume more fuel. Genuine BMW spark plugs can last about 40,000 to 60,000 kilometers, but they should be replaced once worn. I recommend checking the specifications at a 4S shop and avoiding random off-brand replacements. Also, it depends on the model—high-performance versions tend to use more durable brands.
