New spark plugs last 4x longer! says Bosch

June 17, 2011

The new Bosch Iridium spark plug was developed using the same innovations in design, manufacturing processes and materials found in Bosch spark plugs used by domestic, Asian, and European original equipment manufacturers.

The Bosch Group says the iridium spark plug will last four times longer than standard copper plugs.

“The move to smaller engines and from carburetors to port injection to gasoline direct injection required a significant change in spark plug technology,” says Mark Wilkinson, group product manager for spark plugs.

“Developed in close collaboration with automakers, the fine-wire center electrode with our proprietary iridium alloy meets the demanding conditions in modern engines. By maintaining the OE spark position/gap and using ‘best-in-class’ materials... and exclusive manufacturing processes, new Bosch Iridium surpasses all other spark plugs by delivering both performance and long life -- all at a competitive price.”

The Bosch Iridium line has 15 part number, which will cover 71% of vehicles in operation. The program will be expanded in the coming months to include additional part numbers and vehicle coverage.

Bosch Iridium is backed by a seven-year satisfaction guarantee and a 12-month professional technician warranty for repair shops that includes:

* labor charges for replacement covered by Bosch for up to one year after installation;

* a toll-free number for processing and tracking claims due to defects in materials and workmanship; and

* a downloadable online claim form.

“The premium spark plug segment has been growing steadily, and Bosch’s strategy has been to use the latest OE-driven innovations to offer a premium quality product to the motorist while enhancing profitability for the entire service industry," says Wilkinson.
