Our best-in-class laser welding processes ensure durable precision welds which will prevent micro fractures caused by the intense heating and cooling experienced by a spark plug over its lifetime,” Wilkinson added. “Bosch Iridium’s outstanding performance and durability are due to its basic design: the extensive use of precious metal in both the center and tapered ground electrodes, and the unique Bosch 360-degree Continuous Wave Laser Welding process.

“The move to smaller engines and from carburetors to port injection to gasoline direct injection (GDI) required a significant change in spark plug technology,” said Mark Wilkinson, group product manager for Spark Plugs for Bosch. New Bosch Iridium provides exceptional ignitability, performance and durability, offering four times longer service life compared to standard copper plugs, according to the company. The new Bosch Iridium spark plug was developed using the same leading-edge innovations in design, manufacturing processes and materials found in Bosch spark plugs used by domestic, Asian and European original equipment manufacturers (OEMs) around the world, the company says.
