BMW Genuine Ignition Coil & NGK Spark Plug Set (4x) — N20 Engine

NGK's SILZBR8D8S plugs feature a fine-wire iridium center electrode and a platinum ground electrode, delivering consistent spark energy, improved cold-start performance, and long service life under boost. Combined with BMW's OEM ignition coils — engineered to deliver the precise voltage curve the DME expects — this kit ensures clean combustion, smooth idle, and no misfires that cheaper aftermarket alternatives often introduce.

This is the no-compromise choice for a scheduled tune-up or a misfire diagnosis. Buying OEM means no compatibility guesswork, no heat-range concerns, and no voided warranties. If you're keeping your N20-powered BMW running the way it left the factory, this four-piece set is exactly what belongs in the engine bay.
