Bosch 7955 Spark Plug

Bosch Nickel Spark Plug 7955 Overview

Bosch 7955 is a conventional nickel-copper spark plug built for steady ignition performance and value. It uses a heavy-duty nickel center electrode with a copper core, plus a tapered V-profile ground electrode to support consistent spark delivery in a wide range of older import and domestic applications.

The Bosch Nickel line focuses on OE-style replacement coverage for vehicles such as Dodge Neon, Chrysler Neon, Volvo C70, and Nissan Sentra applications that call for a standard nickel plug. Bosch 7955 is a direct choice when you need a conventional 4-cycle spark plug with a resistor design and OE-matching service characteristics.

Key Features

• Conventional nickel-copper spark plug for secondary ignition service
• Nickel-yttrium center electrode with copper core for durable performance
• Tapered V-profile ground electrode for stable spark exposure
• Resistor design rated at 6000 ohms
• Flat seat, non-projected ceramic insulator, standard ground configuration
• 14 mm thread diameter, 19 mm reach, 16 mm hex size
• Manufacturer heat range 7 for OE-style application matching

Detailed Description

Bosch 7955 is engineered to meet or exceed original equipment specifications for nickel-copper core spark plugs. The nickel-yttrium center and ground electrode materials are paired with a copper core to support dependable ignition performance in everyday driving. This spark plug is a practical OE replacement for vehicles that specify a conventional resistor plug with a flat seat and standard ground electrode layout.

For fitment-based searches, Bosch 7955 is commonly selected for Dodge Neon spark plug replacement, Chrysler Neon ignition service, and Volvo C70 spark plug applications. It also appears in coverage for Nissan Sentra, INFINITI G20, Kia Spectra, and other vehicles listed in the fitment data where a nickel plug is specified.

What This Spark Plug Helps Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent ignition output
• Misfire conditions related to aged secondary ignition components
• Reduced throttle response from degraded spark delivery
• Maintenance replacement for OE-style nickel spark plug service intervals

Installation Notes and Tips

Verify the vehicle’s under-hood gap specification before installation, since listed applications include different gap requirements. Bosch 7955 uses a 14 mm thread, 19 mm reach, 16 mm hex, flat seat, and resistor construction, so confirm those specifications match the engine before ordering. For vehicles such as Dodge Neon, Chrysler Neon, and Volvo C70, follow the manufacturer gap and torque specifications during installation.

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

Quality Assurance

Bosch designs the Nickel line as an OE-style conventional spark plug family for value-focused replacement service. Part number 7955 is built to align with original equipment requirements for nickel-copper core spark plugs and to provide consistent fitment across the listed applications.
