About the Bosch EVO Spark Plug Line
The Bosch EVO line focuses on combining advanced electrode materials such as iridium and platinum with precise engineering to enhance ignition reliability and longevity. The EVO 8505 spark plug benefits from this technology by offering a fine wire center electrode and a platinum ground electrode tip, which together improve ignition efficiency and reduce electrode wear in 4-cycle engines.
Technical Details and Features
The Bosch EVO 8505 spark plug features a copper core for both the center and ground electrodes, ensuring excellent thermal conductivity and heat dissipation. The fine wire center electrode design paired with a J-gap ground configuration optimizes spark exposure and combustion efficiency. The flat seat type and 14 mm hex size facilitate proper installation and secure fitment. Additionally, the integrated resistor helps minimize electromagnetic interference, protecting sensitive vehicle electronics.
Compatible Vehicles and Applications
- Compatible with Acura models such as Accord and Integra
- Fits Honda vehicles including Civic and CR-V
- Suitable for Infiniti Q50 and Q60
- Designed for Lexus LS500, LX600, and LX700h
- Works with Maserati Levante and Nissan GT-R
- Also compatible with Smart Fortwo, Toyota Sequoia, Tundra, and Volvo S60, V60, XC90 models
Common Issues Addressed by Bosch EVO 8505 Spark Plug
- Misfiring or rough idling due to worn electrodes
- Poor fuel efficiency caused by incomplete combustion
- Difficulty starting engines in cold conditions
- Engine hesitation or loss of power under load
- Excessive emissions from inefficient ignition
Installation Notes and Tips
Ensure the spark plug gap is set to the specified 0.7 mm pre-gap before installation. Use a 14 mm socket wrench for proper tightening to avoid damage to the flat seat. The non-removable nut electrical terminal requires compatible ignition wire connectors. Always follow manufacturer torque specifications and inspect the spark plug threads for cleanliness to ensure a secure fit.
Quality Assurance and Warranty
Bosch manufactures the EVO 8505 spark plug to meet strict quality standards, utilizing durable materials such as iridium and platinum for extended service life. The resistor built into the plug reduces electrical interference, supporting vehicle electronics. While specific warranty details are not provided, Bosch products typically adhere to industry quality assurance protocols.
