OE Fine Wire Double Iridium Product Line Details

The OE Fine Wire Double Iridium line by Bosch features spark plugs with fine wire iridium center electrodes and platinum-iridium ground electrodes. This combination enhances durability and ignition efficiency, providing stable spark delivery and extended service life. The double iridium design reduces electrode wear and supports consistent performance in secondary ignition systems.

Technical Description and Features

This spark plug incorporates a tapered ground electrode tip made from platinum-iridium and nickel-yttrium, paired with an iridium center electrode tip. The center electrode core is composed of nickel-yttrium and copper, optimizing conductivity and heat dissipation. The ceramic insulator is projected and designed to withstand high temperatures and electrical stress. With a resistance of 6000 ohms, the spark plug includes an integrated resistor to reduce electromagnetic interference. The flat seat and 16 mm hex size facilitate proper installation and sealing.

Compatible Vehicles and Applications

The Bosch 9619 spark plug is compatible with various Acura and Honda models, including:

Acura ILX, MDX, RDX, RL, TL, TSX, ZDX
Honda Accord, Accord Crosstour, Civic, CR-V, Crosstour, Odyssey, Pilot, Ridgeline

It is designed specifically for 4-cycle engines requiring a heat range 6 spark plug with a 1.1 mm pre-gap size.

Common Issues Addressed by Bosch 9619 Spark Plug

Engine misfires due to worn or damaged spark plugs
Reduced fuel efficiency from incomplete combustion
Difficulty starting the engine in cold conditions
Rough idling or hesitation during acceleration
Excessive electrode wear causing ignition instability

Installation Notes and Tips

Ensure the spark plug gap is set to 1.1 mm before installation
Use a torque wrench to tighten to manufacturer specifications to avoid damage
Inspect the spark plug threads and cylinder head for debris before installation
Replace spark plugs in sets to maintain consistent engine performance
Check compatibility with your specific Acura or Honda model and engine type
