Bosch OE Fine Wire Double Iridium Spark Plug 9619

Bosch 9619 is an OE Fine Wire Double Iridium spark plug built for direct replacement in a wide range of Honda and Acura applications. It combines a fine-wire iridium center electrode with a laser-welded ground electrode to support consistent ignition performance and long service life.

The Bosch OE Fine Wire Double Iridium line focuses on OE-style fit and durable electrode construction. For drivers searching for a Bosch 9619 spark plug for Honda Accord, Civic, CR-V, or Acura MDX applications, this plug is engineered to match preset-gap requirements and original iridium-equipped engines.

Key Features

Fine-wire iridium center electrode for strong ignitability
Laser-welded tapered ground electrode for stable spark delivery
Double iridium construction for extended service life
Preset gap of 1.1 mm; do not gap before installation
Resistor design for reduced electrical noise
Flat seat, projected insulator, and 12 mm thread diameter
OE-style replacement for select Honda and Acura 4-cycle engines

Product Details

Bosch Part Number 9619 uses an iridium-alloy center firing pin and a ground electrode with iridium alloy inlay to maintain performance over time. The nickel-yttrium and copper core materials help support heat transfer, while the ceramic insulator and projected tip design are suited to modern ignition systems. This spark plug is specified for vehicles that originally used iridium plugs, including many Honda Accord, Civic, CR-V, Odyssey, Pilot, Ridgeline, and Acura MDX applications.

This part cross-references NGK (e.g., 9723, 9807) for the same application.

What It Helps Address

Misfires caused by worn or eroded spark plug electrodes
Hard starting from weak ignition output
Rough idle related to inconsistent spark delivery
Reduced throttle response from degraded plug performance
Service intervals that call for OE-style iridium replacement
