Bosch OE Fine Wire Platinum Spark Plug 6734

Bosch 6734 is an OE Fine Wire Platinum spark plug built for direct replacement service in a wide range of Chrysler, Dodge, Jeep, and Ram applications. It uses a platinum center electrode with a fine-wire firing design to support reliable ignitability and improved fuel efficiency versus conventional copper-core plugs.

The OE Fine Wire Platinum line focuses on factory-style performance with an economical upgrade path for drivers maintaining original-equipment specifications. For vehicles such as the Dodge Durango, Jeep Grand Cherokee, and Ram 1500, Bosch 6734 delivers the electrode design and heat range expected for OE-style ignition service.

Key Features

  • Platinum center electrode tip for consistent spark performance
  • Fine-wire design with tapered ground electrode
  • Resistor spark plug with 6000 resistance
  • Projected ceramic insulator for OE-style combustion chamber placement
  • Flat seat, 14 mm thread diameter, 16 mm hex size
  • Pre-gapped to 1.1 mm; do not gap where OE notes specify preset gap
  • Manufacturer heat range 8 for specified OE applications

Product Details

Bosch OE Fine Wire Platinum 6734 is engineered to meet or exceed original equipment specifications for platinum spark plugs. The nickel-ytttrium ground electrode tip and nickel-ytttrium/copper core construction support stable ignition characteristics, while the platinum firing pin helps maintain electrode durability over service intervals. This part number is used across many late-model Chrysler, Dodge, Jeep, and Ram engines, including Dodge Charger, Dodge Challenger, Jeep Grand Cherokee, Chrysler 300, and Ram 1500 applications.

For fitment-based searches, Bosch 6734 is a direct OE-style spark plug choice for 2014-2025 Dodge Durango, 2021-2024 Jeep Grand Cherokee L, 2018-2024 Ram 1500, 2019-2024 Ram 1500 Classic, and 2014-2023 Chrysler 300. It also covers additional Chrysler, Dodge, Jeep, and Ram models listed in the fitment data, including dual-spark and preset-gap applications where specified.

What It Helps Address

  • Rough idle caused by worn spark plug electrodes
  • Hard starting from weakened ignition output
  • Misfire conditions related to aged plugs
  • Reduced fuel economy from inefficient spark delivery
  • Loss of throttle response from degraded ignition performance

Installation Notes

Verify engine-specific fitment before installation, especially on applications marked do not gap or preset gap. Bosch 6734 is a flat-seat spark plug with a 14 mm thread diameter and 26.5 mm reach, so matching the OE specification is important for proper sealing and combustion chamber placement. Use the vehicle service information for torque and replacement interval guidance.

For Dodge Durango spark plug replacement, Jeep Grand Cherokee ignition service, or Ram 1500 tune-up work, confirm the engine code and OE plug style before ordering. Bosch 6734 is also a relevant search match for Chrysler 300 and Dodge Charger spark plug replacement applications.

Quality Assurance

Bosch OE Fine Wire Platinum spark plugs are built to align with OE requirements for platinum plug applications and are engineered for consistent ignition performance in factory-specified engines. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
