Bosch OE Fine Wire Iridium Spark Plug 9723

Bosch 9723 is an OE Fine Wire Iridium spark plug built for direct replacement service in a range of GM and Saab applications. It uses a fine-wire iridium center electrode, a platinum-iridium tip design, and a preset .9 mm gap for consistent ignition performance in engines that call for this specification.

Compatible With Buick Regal, Buick Verano, Chevrolet Equinox, GMC Terrain, Buick LaCrosse, Chevrolet Captiva Sport, Chevrolet Impala, Chevrolet Malibu, Saab 9-5, Chevrolet Cobalt, Chevrolet HHR, Saturn Sky, and Pontiac Solstice applications listed below.

  • OE Fine Wire Iridium design for stable spark delivery
  • Preset .9 mm gap; do not gap before installation
  • Platinum-iridium center electrode tip with nickel-yttrium and copper core materials
  • Resistor plug with 6000 resistance specification
  • Tapered seat, 14 mm thread diameter, 16 mm hex size, 25 mm reach
  • Ceramic insulator and non-projected insulator type

Product Details and Application

Bosch OE Fine Wire Iridium 9723 follows original-equipment style spark plug construction for engines that require a tapered-seat, 4-cycle plug with a preset gap. The ultra-fine center electrode helps maintain a focused spark kernel, while the resistor design supports ignition system noise control. This spark plug is listed for 2010-2017 Chevrolet Equinox, 2010-2017 GMC Terrain, 2011-2017 Buick Regal, 2012-2017 Buick Verano, 2010-2016 Buick LaCrosse, 2012-2015 Chevrolet Captiva Sport, 2014 Chevrolet Impala, 2013-2014 Chevrolet Malibu, 2011 Saab 9-5, 2008-2010 Chevrolet Cobalt, 2008-2010 Chevrolet HHR, 2007-2010 Saturn Sky, and 2007-2009 Pontiac Solstice. This part number 9723 is also a direct reference point when matching OE-style ignition service parts for these vehicles.

This part cross-references Bosch 9723 for the same application.

What It Helps Address

  • Hard starting caused by worn spark plug electrodes
  • Misfire conditions related to degraded ignition performance
  • Rough idle from inconsistent spark delivery
  • Reduced throttle response from aged secondary ignition components
  • Maintenance replacement for OE-style iridium spark plug service

Installation Notes and Tips

Verify the engine calls for a tapered-seat, 14 mm spark plug with a 25 mm reach and 16 mm hex before installation. The gap is preset, so do not adjust it. Follow the vehicle service procedure for torque and removal/installation sequence, and confirm the original plug specification matches the listed OE Fine Wire Iridium application. For fitment searches, Bosch 9723 is commonly referenced for Chevrolet Equinox, GMC Terrain, and Buick Regal ignition service.

Quality Assurance

Bosch positions the OE Fine Wire Iridium line as an OE-level spark plug family focused on performance and service life. The iridium center electrode and platinum-iridium tip materials are selected for durable ignition service in the listed applications.
