BMW 7 Series Spark Plugs Malaysia

Iridium Plugs — Worth the Premium
The 7 Series's B58 3.0T or N63 4.4T V8 engine requires iridium spark plugs — these are more expensive than standard copper or platinum plugs but last significantly longer (60,000 km vs 20,000 km). Using cheaper non-iridium plugs in a BMW direct-injection turbo engine causes rough idle, misfires, and can trigger coilpack damage. At 60,000 km intervals, iridium plugs actually cost less per kilometre than cheaper alternatives. Always replace all plugs as a set and inspect coils while the engine is open.
