Bosch 7569 Spark Plug

Overview

Bosch 7569 is a conventional nickel-copper spark plug built for steady ignition performance and value. It uses a yttrium-enhanced nickel center electrode with a copper core and is engineered to meet or exceed OE specifications for nickel-copper core spark plugs.

Compatible With Jeep Cherokee, Comanche, Wagoneer, CJ5, CJ7, and Scrambler applications listed below, Bosch Nickel 7569 supports older ignition systems that call for a tapered-seat, resistor-style plug with a standard ground design.

Key Features

• Nickel-copper construction with a copper core for durable spark plug service.
• Yttrium-enhanced center electrode for improved electrode durability.
• Resistor design with 6000 resistance for ignition system compatibility.
• Standard ground electrode tip and standard ground configuration.
• Non-projected ceramic insulator with tapered seat and 11.2 reach.
• Short-style, 4-cycle spark plug with removable nut terminal.

Product Details

This Bosch spark plug is part of the Nickel line, a conventional plug family focused on OE-style fit and dependable operation in applications that specify nickel-copper core construction. Part number 7569 is a practical replacement choice for classic Jeep ignition service, including Jeep Cherokee, Jeep Wagoneer, and Jeep CJ-series applications where the listed heat range, seat type, and terminal style match the original specification.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

Common Issues It Can Address

• Hard starting caused by worn spark plug electrodes.
• Rough idle from inconsistent ignition firing.
• Misfire conditions related to aged plugs.
• Reduced throttle response from degraded spark delivery.
• Service replacement needs for original-style nickel-copper plugs.

Installation Notes

Verify the tapered seat, reach, heat range, and terminal style before installation. Check and set the pre-gap to .9 if required by the application, and confirm the 16 mm hex clearance during service. Use the vehicle service specification for final torque and ignition system checks.

Quality Assurance

Bosch engineers this Nickel spark plug to meet or exceed Original Equipment specifications for nickel-copper core spark plugs.
