2. Part Number References: Designed as a double-iridium replacement for applications that specify 0242230806, 0 242 230 806, FQR8LEU2 or N40. Compare the complete reference on the spark plugs currently fitted before ordering. The Bosch name and reference numbers identify compatibility only and do not indicate that this product is manufactured or supplied by Bosch.
3. Double Iridium Electrode Design: Iridium tips are used on both the fine centre electrode and the ground electrode. This point-to-point electrode structure is designed to provide a concentrated spark path, support stable ignition and reduce the voltage required to bridge the electrode gap compared with a wider conventional electrode design.
