Detailed Description

Bosch 79010 is a nickel spark plug designed for engines that call for a copper/nickel-style OE replacement. The nickel center electrode and nickel ground electrode tip are paired with a copper core to help maintain stable ignition performance under regular driving and sustained high-speed use. Its flat seat, 16 mm hex size, and 19 mm reach support common factory-style fitments across select Saab 900, Saab 9000, Saab 9-3, Infiniti G20, Nissan Sentra, Nissan 200SX, Nissan Pathfinder, Nissan Pickup, Nissan D21, and Nissan NX applications.

For drivers searching for a Bosch 79010 spark plug for Saab 900 or a Bosch 79010 spark plug for Nissan Sentra, this part is built around the specifications commonly used in those original equipment applications. The Bosch Nickel line is aimed at straightforward replacement service where the correct heat range, electrode material, and gap specification matter for ignition consistency.

What It Helps Address

• Hard starting caused by worn spark plug electrodes
• Rough idle from weak or inconsistent spark output
• Misfire conditions related to aged ignition components
• Reduced throttle response from degraded plug performance
• Service replacement needs on OE nickel-copper spark plug applications

Installation Notes and Tips
