Detailed Product Description

The Bosch OE Fine Wire Platinum spark plug, part number 6723, features a platinum center electrode tip that provides long-lasting wear resistance and stable ignition. The ground electrode tip is tapered and made from nickel-yttrium, which enhances spark exposure and combustion efficiency. This spark plug includes a 6000 ohm resistor to minimize radio frequency interference, ensuring smooth operation of vehicle electronics.

Its ceramic insulator is non-projected, offering excellent dielectric strength and heat dissipation. The spark plug has a thread diameter of 14mm, a reach of 17.5mm, and a pre-gap size of 1.1mm, matching the specifications required by many Chevrolet, Ford, GMC, and Mazda vehicles. The heat range of 8 is suitable for moderate to high operating temperatures, helping to prevent fouling and pre-ignition.

About the OE Fine Wire Platinum Product Line

The OE Fine Wire Platinum line from Bosch is designed to meet or exceed original equipment specifications. This product line focuses on fine wire platinum electrodes that provide consistent spark performance and extended service life. The use of platinum in the center electrode reduces wear and maintains a stable spark gap, which is critical for maintaining engine efficiency and emissions compliance over time.

Applications and Common Issues Addressed

• Restores proper ignition in Chevrolet Cavalier, Ford Mustang, and GMC S10 engines
• Helps resolve misfires and rough idling caused by worn spark plugs
• Improves cold start performance in vehicles like the Mazda B2300 and Ford Explorer
• Reduces engine hesitation and power loss in models such as the Pontiac Firebird and Mercury Cougar
• Supports consistent combustion in 4-cycle engines requiring a 14mm spark plug

Installation Notes and Tips

• Ensure the spark plug gap is set to 1.1mm before installation if not pre-gapped
• Use a torque wrench to tighten the spark plug to manufacturer specifications to avoid damage
• Check compatibility with your vehicle’s make and model, including Chevrolet, Ford, GMC, Isuzu, Mazda, Mercedes-Benz, Mercury, and Pontiac
• Inspect the spark plug threads and cylinder head for damage before installation
• Replace spark plugs in sets to maintain balanced engine performance
