Bosch OE Fine Wire Platinum Spark Plug 6704

Bosch OE Fine Wire Platinum spark plug 6704 is built for drivers who want OE-style ignition performance with a platinum center electrode and a tapered ground electrode. It is engineered to meet or exceed original equipment specifications for platinum spark plugs and is listed with preset gap, so it is ready for the applications shown below.

Key Features

  • Fine wire platinum firing pin on the center electrode for improved ignitability
  • Tapered ground electrode design for efficient spark delivery
  • Resistor spark plug with 6000 resistance
  • Projected ceramic insulator design
  • 14 mm thread diameter, 17.5 mm reach, 16 mm hex size
  • Preset gap; do not gap before installation on listed applications
  • OE Fine Wire Platinum line for OE-style replacement needs

Product Details

The Bosch OE Fine Wire Platinum line is focused on direct-replacement ignition performance for vehicles that call for a platinum spark plug. Part number 6704 uses a platinum center electrode tip, nickel-ytttrium ground electrode tip material, and a nickel-ytttrium/copper core to support consistent spark delivery. The tapered seat, projected insulator, and resistor design align with modern ignition system requirements found in many Chevrolet Silverado 1500, GMC Sierra 1500, and Cadillac Escalade applications.

This spark plug is a practical OE-style upgrade from conventional copper core plugs and is also listed across a wide range of GM trucks, SUVs, and performance cars, including Chevrolet Express, Tahoe, Suburban, Camaro, Corvette, and GMC Yukon models. If you are searching for Bosch 6704 spark plug fitment for a Chevrolet Silverado 2500 HD or GMC Sierra 3500 HD, this part number is one to verify against the vehicle application chart.

This part cross-references AC Delco 41-110 and NGK 3186 for the same application.

What It Helps Address

  • Rough idle caused by worn spark plug electrodes
  • Hard starting from weak or inconsistent ignition spark
  • Misfire conditions tied to aged plugs
  • Reduced fuel economy from inefficient combustion
  • Loss of throttle response in high-mileage ignition systems

Installation Notes

  • Compatible With the listed Chevrolet, GMC, Cadillac, Buick, Pontiac, Saab, Hummer, Isuzu, and Geo applications only.
  • Do not gap this plug on the listed vehicles; the gap is preset.
  • Verify engine code and OE plug specification before installation.
  • Use the correct torque procedure for the tapered seat design.
  • Inspect ignition coils, boots, and wires during service to avoid repeat misfire concerns.

Quality Assurance

Bosch engineers the OE Fine Wire Platinum line to meet or exceed original equipment specifications for platinum spark plugs. Part number 6704 is built for OE-style fitment and ignition performance across the confirmed vehicle applications shown in the fitment data.
