Product Details

The Bosch Nickel product line focuses on conventional spark plug construction that meets or exceeds original equipment specifications for nickel-copper core applications. Bosch 7995 uses a nickel-y yttrium center electrode with a copper core to balance conductivity and durability, while the tapered V-profile ground electrode supports stable ignition characteristics. This spark plug is a direct-fit style for select older European and Japanese vehicles, including Saab 900, Volvo 740, Volvo 940, Volkswagen Corrado, Maserati Spyder, Maserati 430i, and Honda Civic listings shown in the fitment data.

This part cross-references common OE-style spark plug applications where a conventional nickel-copper design is specified.

Common Issues This Spark Plug Can Address

• Hard starting caused by worn or fouled spark plugs
• Rough idle from inconsistent spark delivery
• Misfire symptoms related to aged secondary ignition components
• Reduced throttle response from degraded plug electrodes
• Service intervals overdue on OE-style nickel spark plug applications

Installation Notes and Tips

• Verify the vehicle’s required thread diameter, reach, seat type, and heat range before installation.
• Check the specified gap for the application; fitment notes list gaps such as 0.024 in and 0.028 in on certain vehicles.
• Inspect ignition wires, coil components, and plug wells during service to avoid repeat misfire concerns.
• Use the correct torque procedure for flat-seat spark plugs to help prevent sealing issues.

Quality Assurance

Bosch designs the Nickel line to meet or exceed original equipment specifications for nickel-copper core spark plugs. Part number 7995 follows conventional OE-style construction for dependable service in the listed applications.
