OE Fine Wire Double Iridium Pin-to-Pin Product Line Details

The OE Fine Wire Double Iridium Pin-to-Pin line by Bosch focuses on precision ignition components that combine fine wire iridium electrodes with a pin-to-pin ground electrode tip design. This configuration enhances spark efficiency and electrode longevity, making it suitable for modern engines like the Honda CR-Z. The use of double iridium and platinum materials ensures stable performance under various operating conditions.

Technical Description and Specifications

The Bosch FR7DII35V spark plug features a non-projected ceramic insulator designed to withstand high temperatures and electrical stress. The center electrode is crafted from iridium with a nickel-yttrium and copper core, providing a stable and long-lasting spark. The ground electrode tip uses a platinum-iridium and nickel-yttrium alloy, arranged in a pin-to-pin design to optimize spark exposure and combustion efficiency. With a manufacturer heat range of 7, this spark plug balances heat dissipation and performance for the Honda CR-Z's engine requirements.

Applications and Problem Solving

  • Compatible with Honda CR-Z models requiring a 14 mm thread diameter and 19 mm reach spark plug
  • Addresses misfires caused by electrode wear or poor spark quality
  • Reduces electrical interference with a built-in 6000 ohm resistor
  • Improves cold start reliability and throttle response
  • Helps maintain fuel efficiency by ensuring consistent ignition

Installation Notes and Tips

When installing the Bosch FR7DII35V spark plug, ensure the pre-gap of 1.3 mm is maintained for optimal performance. Use a 16 mm socket wrench for proper torque application. The flat seat design requires careful seating to avoid leaks or misalignment. It is recommended to replace all spark plugs simultaneously to maintain engine balance and performance.

Quality Assurance and Warranty

Bosch manufactures the FR7DII35V spark plug to meet strict OEM standards, ensuring compatibility and durability for the Honda CR-Z. The use of high-grade materials like iridium and platinum contributes to extended service life. While specific warranty details are not provided here, Bosch products typically come with manufacturer-backed quality guarantees.
