About the Bosch Nickel Spark Plug Line

The Bosch Nickel product line focuses on spark plugs that combine nickel-based electrode materials with reliable construction to meet the ignition needs of many domestic vehicles. The Nickel 7980 spark plug features nickel-yttrium alloy tips on both center and ground electrodes, enhancing wear resistance and maintaining consistent spark quality over time. This line is suitable for standard ignition systems requiring a 6000 ohm resistor to reduce radio frequency interference.

Technical Details and Compatibility

The Bosch 7980 spark plug is designed for use in 4-cycle engines and features a single ground electrode with a tapered v-profile tip to optimize spark exposure and combustion efficiency. The 1.5 mm pre-gap size is factory set to ensure proper ignition timing without additional adjustment. With a 14 mm thread diameter and 17.5 mm reach, this spark plug fits a variety of GM and Ford vehicles, including Buick LeSabre, Cadillac DeVille, Chevrolet Camaro, Ford C1500, and Pontiac Firebird, among others.

Common Applications and Problem Solving

• Restores consistent engine starting and smooth idling
• Reduces misfires caused by worn or damaged spark plugs
• Improves fuel efficiency by ensuring complete combustion
• Minimizes radio frequency interference with built-in resistor
• Prevents electrode wear for longer service intervals

Installation Notes and Tips

Ensure the spark plug gap is verified before installation, although the Bosch 7980 comes pre-gapped at 1.5 mm. Use a 16 mm socket wrench for proper tightening to the manufacturer’s torque specifications. The tapered seat type requires careful seating to avoid cross-threading. Always replace spark plugs in sets to maintain balanced engine performance.

Quality Assurance and Warranty

Bosch manufactures the 7980 spark plug to meet strict quality standards, using high-grade ceramic insulators and nickel-yttrium alloy electrodes for durability and reliable ignition. This spark plug includes a built-in resistor to meet OEM specifications for noise suppression. Warranty details should be confirmed with the original equipment manufacturer or Bosch documentation.
