Product Details

Bosch Nickel line spark plugs focus on practical ignition service for everyday drivability and maintenance. Part number 79006 uses a nickel-ytrium center electrode with a copper core and nickel ground electrode tip material to support consistent spark delivery in engines that call for a conventional copper/nickel-style plug. The design follows OE specifications for nickel-copper core spark plugs and is listed for a wide range of Toyota and Lexus models, including 1995-2004 Toyota Tacoma, 2000-2004 Toyota Tundra, and 1996-2002 Toyota 4Runner. It also appears in fitment for Lexus SC300 and GS300, plus Toyota Corolla, Sienna, Paseo, Tercel, and T100 applications. This part number, 79006, is a direct service option for vehicles that specify the listed plug dimensions and heat range.

This part cross-references no additional part numbers provided in the supplied data.

What It Helps Address

• Hard starting caused by worn spark plug electrodes
• Rough idle from inconsistent ignition output
• Misfire conditions related to aged plugs
• Reduced throttle response from degraded spark quality
• Maintenance replacement for OE-style nickel-copper plug applications

Installation Notes

Verify the vehicle’s required gap, thread diameter, reach, seat type, and heat range before installation. Fitment notes in the catalog list a 0.044 in gap for several Toyota and Lexus applications, so confirm the engine specification before use. Bosch 79006 is a flat-seat spark plug with a projected insulator and multiple ground configuration, so install only where those specifications match the engine requirement. Use proper spark plug service procedures and torque to the vehicle manufacturer’s specification.

Quality Assurance

Bosch designs this Nickel spark plug line to meet or exceed original equipment specifications for nickel-copper core spark plugs. The construction uses a nickel-ytrium center electrode with copper core materials selected for conventional ignition service in the listed Toyota and Lexus applications.
