Bosch OE Fine Wire Double Iridium Spark Plug

Bosch 96323 is an OE-style fine wire spark plug built for direct ignition performance and long service life. Its double iridium pin-to-pin design uses iridium-alloy electrodes to support efficient flame-kernel growth, stable combustion, and consistent ignition in modern engines.

Compatible With select Genesis, Hyundai, Kia, and Mitsubishi applications, including Hyundai Sonata, Hyundai Santa Fe Sport, Kia Optima, Kia Sorento, and Mitsubishi Outlander fitments listed below. Bosch 96323 is a direct replacement spark plug for vehicles that specify a preset gap and OE fine wire double iridium construction.

Key Features

Double iridium pin-to-pin electrode design for OE-style ignition performance
Iridium-alloy firing pin and iridium-alloy pin on the ground electrode
Fine wire construction supports efficient flame-kernel growth
Resistor spark plug with 6000 resistance
Projected ceramic insulator for modern 4-cycle engines
Flat seat, 12 mm thread diameter, 26.5 mm reach, and 16 mm hex size
Preset 1 mm gap; do not gap before installation

Product Details

Bosch OE Fine Wire Double Iridium Pin-to-Pin spark plugs are engineered around Bosch’s OE-focused spark plug technology. The 96323 uses two iridium-alloy electrodes to maintain sharp ignition characteristics and long wear resistance, while the nickel-yyttrium and copper core materials support heat transfer and durability. This design is well suited for engines that call for iridium plugs with a preset gap, including applications across Hyundai Genesis, Hyundai Sonata, Kia Optima, Kia Sorento, and Mitsubishi Outlander platforms. This part cross-references Denso (e.g., 3461) for the same application.

What It Helps Address

Hard starting caused by worn spark plug electrodes
Rough idle from inconsistent ignition output
Misfire conditions related to plug wear or incorrect gap setting
Reduced throttle response from degraded spark quality
Service intervals shortened by standard copper plug wear

Installation Notes

Verify the engine calls for Bosch 96323 or the listed OE fine wire double iridium specification.
Do not gap this spark plug; the gap is preset from the factory.
Confirm thread diameter, reach, seat type, and hex size before installation.
Use the vehicle service manual for torque and removal procedures.
Inspect ignition coils and boots during spark plug service to avoid repeat misfire concerns.

Quality Assurance

Bosch builds this spark plug to OE-level specifications for modern ignition systems, with iridium-alloy electrode materials selected for performance and extended service life.

This part fits 71 vehicles

Always verify fitment with your vehicle's VIN if unsure. Submodel & trim restrictions may apply.
