Details on Bosch OE Fine Wire Double Iridium Product Line

The OE Fine Wire Double Iridium line from Bosch focuses on delivering spark plugs with fine wire electrodes made from double iridium materials. This design enhances electrode longevity and ignition reliability, which is critical for maintaining optimal engine performance in vehicles such as the Dodge Dart and Jeep Renegade. The combination of iridium and platinum materials in the electrodes ensures consistent spark delivery and resistance to wear under demanding conditions.

Technical Description and Specifications

This Bosch spark plug features a center electrode tip made of iridium, known for its high melting point and wear resistance, paired with a ground electrode tip composed of platinum-iridium and nickel-yttrium. The core of the center electrode combines nickel-yttrium and copper to optimize conductivity. The ceramic insulator is projected and designed to withstand high temperatures and electrical stress. With a 0.7 mm pre-gap and a flat seat, this spark plug is tailored for 4-cycle engines requiring precise ignition timing and stable combustion. The resistor built into the plug (6000 ohms) helps minimize radio frequency interference, ensuring compatibility with modern vehicle electronics.

Compatible Vehicles and Common Applications

• Dodge 124 Spider, Dart
• Fiat 500, 500L, 500X
• Jeep Renegade

This spark plug is specifically designed for these models, providing a direct replacement that meets original equipment standards.

Common Issues Addressed by Bosch Spark Plug 96320

• Misfires and rough idling due to worn or fouled plugs
• Reduced fuel efficiency from incomplete combustion
