BMW Z4 Spark Plugs - NGK Laser Iridium ('06-'07)

These NGK Laser Iridium spark plugs are OE-equivalent replacements for BMW Z4 models from 2006–2007, designed to provide reliable ignition and long service life. They are a direct-fit option for enthusiasts seeking factory-style performance with improved durability.

Built to NGK's OE standards, Laser Iridium plugs feature a fine iridium center electrode that offers greater hardness and wear resistance than platinum, helping maintain a consistent spark gap over time. The high-grade pure alumina ceramic insulator and a 98% pure copper core help manage heat and provide dependable starts across a wide range of operating conditions. Many Laser Iridium designs also include a platinum pad on the ground electrode to ensure even wear in distributorless ignition systems. These plugs are sold as the common NGK ILZFR6D11 configuration in a box of four and are recommended for vehicles originally equipped with fine-wire iridium alloy plugs.
