BMW 5 Series Spark Plugs - NGK - Laser Iridium - `06-`07. Direct OE-equivalent spark plugs designed for 2006–2007 BMW 5 Series models, offering reliable starts and consistent combustion for drivers who demand dependable ignition performance.

NGK Laser Iridium plugs combine a fine iridium-tipped center electrode and a durable ground electrode design to provide long life and stable firing. The iridium tip is significantly harder than platinum, helping maintain gap integrity under high combustion temperatures. NGK’s high-grade pure alumina ceramic insulator and a 98% pure copper core aid heat transfer and reduce the risk of overheating. Many Laser Iridium plugs also include a platinum pad on the ground electrode to promote even wear in distributorless ignition systems. These come as the NGK ILZFR6D11 box of four and are recommended for vehicles originally equipped with fine-wire iridium alloy plugs.
