Overview of Bosch OE Fine Wire Platinum Spark Plug 6704

The Bosch OE Fine Wire Platinum Spark Plug 6704 is engineered for reliable ignition performance in a range of GM vehicles including Chevrolet, GMC, Cadillac, and Buick models. Designed with precision materials and specifications, this spark plug supports efficient combustion and consistent engine operation.

  • Platinum center electrode tip for enhanced durability
  • Tapered ground electrode tip design for improved spark efficiency
  • 6000 ohm resistance resistor to reduce electrical noise
  • Ceramic projected insulator for optimal heat dissipation
  • Standard ground configuration with a single ground electrode
  • Compatible with 4-cycle engines requiring a 14mm thread diameter and 17.5mm reach
  • Hex size 16mm for standard installation tools

Detailed Product Features and Specifications

This Bosch spark plug features a platinum center electrode tip, which provides longer service life and stable performance compared to conventional electrodes. The ground electrode tip is tapered and made from nickel-yttrium, designed to optimize spark exposure and combustion efficiency. The spark plug includes a 6000 ohm resistor to minimize radio frequency interference, ensuring smooth operation of vehicle electronics.

The ceramic insulator is projected and constructed to withstand high temperatures, supporting the manufacturer heat range rating of 8. The spark plug has a tapered seat type and a thread diameter of 14mm with a reach of 17.5mm, making it suitable for a variety of GM vehicles such as the Chevrolet Silverado 1500, Cadillac Escalade, and Buick LaCrosse.

About the OE Fine Wire Platinum Brand Line
