Bosch OE Fine Wire Double Iridium Spark Plug 9612

Bosch 9612 is an OE Fine Wire Double Iridium spark plug built for direct replacement service in a wide range of GM vehicles, including Chevrolet Impala, Malibu, Monte Carlo, and Silverado applications. Its preset gap, fine-wire iridium firing pin, and laser-welded electrode design support consistent ignition performance and long service life.

Key Features

  • Fine-wire double iridium construction for durable electrode wear characteristics
  • Laser-welded tapered ground electrode for stable spark exposure
  • Iridium-alloy center electrode firing pin for precise ignition
  • Projected ceramic insulator design
  • Resistor plug with 6000 ohm resistance
  • Preset 1.1 mm gap; do not gap before installation
  • 14 mm thread diameter, 17.5 mm reach, 16 mm hex

Product Details

The Bosch OE Fine Wire Double Iridium line is engineered around OE-style ignition requirements, combining a fine center electrode with an iridium-alloy ground electrode inlay to promote reliable spark delivery and extended service life. Part number 9612 uses a tapered seat, projected insulator, and nickel-ytttrium/copper center core materials to support consistent combustion in 4-cycle engines. This spark plug is a direct service choice for vehicles such as Chevrolet Impala, Malibu, and Pontiac G6, where the original application calls for a preset iridium plug.

This part cross-references AC Delco 41-103 and NGK 97506 for the same application.

What It Helps Address

  • Rough idle caused by worn or inconsistent spark plugs
  • Hard starting from weak ignition output
  • Misfire codes related to electrode wear or gap drift
  • Reduced throttle response from incomplete combustion
  • Service intervals shortened by standard-plug wear in iridium applications

Installation Notes

  • Fits 2006-2011 Chevrolet Impala, N/A
  • Fits 2006-2010 Chevrolet Malibu, N/A
  • Fits 2006-2007 Chevrolet Monte Carlo, N/A
  • Fits 2006-2010 Pontiac G6, N/A
  • Fits 2008-2010 Saturn Vue, N/A
  • Do not gap this plug; the gap is preset from the factory.
  • Verify engine application and original plug material before installation, especially on mixed-fit GM platforms.
  • Use the correct torque procedure for tapered-seat spark plugs to avoid thread or sealing damage.

Quality Assurance

Bosch OE Fine Wire Double Iridium plugs are built to OE-style specifications with laser-welded electrode construction and iridium-alloy materials for consistent ignition performance and long service life. Bosch part 9612 is manufactured for direct replacement use in confirmed applications.
