Product Details

Bosch OE Fine Wire Iridium 96334 is engineered as an OE-style spark plug for modern 4-cycle gasoline engines that call for a fine-wire iridium firing pin. The copper core construction supports heat transfer, while the iridium center electrode and platinum ground tip help maintain stable ignition characteristics under normal operating conditions. This part number is commonly selected for Hyundai Elantra, Hyundai Tucson, Kia Soul, Kia Sportage, and related applications listed in the fitment data.

This part cross-references Bosch 96334 for the same application.

What It Helps Address

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

Installation Notes

Verify engine application, thread diameter, reach, seat type, and heat range before installation. Bosch 96334 uses a 12 mm thread, 16 mm hex, flat seat, and 0.7 pre-gap specification, so confirm the engine calls for those dimensions. Inspect ignition coils and plug wells during service, and follow the vehicle manufacturer’s torque and gap procedures.
