About the Bosch EVO Spark Plug Line

The Bosch EVO line focuses on delivering reliable ignition components with advanced electrode materials such as iridium and platinum. These spark plugs are designed to provide consistent performance and longevity, making them suitable for modern 4-cycle engines like those found in Volkswagen Jetta and Taos vehicles. The EVO series balances durability and efficient combustion to support engine responsiveness and fuel economy.

Technical Details and Features

The Bosch EVO 96349 spark plug features a copper core center electrode with an iridium tip, enhancing wear resistance and maintaining a stable spark over time. The ground electrode uses a platinum tip with a copper core, ensuring excellent conductivity and durability. The resistor built into the plug reduces electrical interference, protecting vehicle electronics. The ceramic insulator with a projected design improves heat dissipation and prevents misfires. With a 0.75 mm pre-gap and a J-gap ground configuration, this spark plug is optimized for reliable ignition in Volkswagen Jetta and Taos 4-cycle engines.

Compatible Applications and Common Issues Addressed

• Compatible with Volkswagen Jetta and Taos models requiring a 12 mm thread diameter spark plug
• Helps resolve engine misfires and rough idling
• Improves cold start performance and throttle response
• Reduces radio frequency interference affecting vehicle electronics
• Supports consistent combustion to prevent power loss and poor fuel economy

Installation Notes and Tips

Ensure the spark plug gap is set to the specified 0.75 mm before installation if adjustment is necessary. Use a 16 mm socket wrench for proper tightening to avoid damage to the flat seat. The Bosch EVO 96349 spark plug is designed for 4-cycle engines and should be installed following manufacturer torque specifications. Avoid over-tightening to maintain the integrity of the ceramic insulator and seat.
