Product Details
The Bosch OE Fine Wire Platinum line is positioned as an economical upgrade from conventional copper core spark plugs while maintaining OE-style fit and function. Part number 6718 uses a platinum firing pin on the center electrode, nickel-ytttrium ground electrode tip material, and a tapered seat design to support reliable spark delivery in 4-cycle gasoline engines. This spark plug is listed across a wide range of GM vehicles, including Chevrolet Malibu, Chevrolet Uplander, Pontiac Montana, Saturn Aura, and Buick Terraza applications. For shoppers comparing Bosch 6718 against OE-style replacements, the preset gap and platinum construction make it a practical service part for ignition maintenance.
What It Helps Address
- Hard starting caused by worn spark plug electrodes
- Rough idle from inconsistent ignition firing
- Reduced fuel economy from degraded spark performance
- Misfire conditions related to aged secondary ignition components
- Loss of throttle response from weak combustion events
Installation Notes
