What is the spark plug brand for the BMW 5 Series B48 engine?

[ConnorLynn]

BMW 5 Series B48 engine spark plug brand is NGK. Spark plug replacement frequency: Platinum spark plugs should be replaced at approximately 40,000 kilometers. Performance degradation manifests as cathode erosion, causing changes in ignition gap and reduced stability, so regular replacement is recommended. Ordinary nickel alloy spark plugs need to be replaced every 20,000 kilometers. It is advised not to exceed 40,000 kilometers, otherwise ignition efficiency will decrease, leading to reduced engine power. Iridium spark plugs can last 60,000 to 80,000 kilometers before replacement. Main types of spark plugs: Spark plugs, commonly known as ignition plugs, function by releasing the high-voltage pulse electricity delivered by the high-voltage wire (spark plug wire), breaking down the air between the two electrodes to generate an electric spark that ignites the air-fuel mixture in the cylinder. Main types include: standard spark plugs, extended insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, surface-gap spark plugs, etc.
