Bosch - Platinum Spark Plugs

• Only Bosch uses a pure platinum center electrode, heat-fused into an extended insulator

• Reaches self-cleaning temperature only seconds after starting
• Electrode gap remains virtually unchanged throughout the plug's longer service life; no need to clean or re-gap

• Heavy-duty tapered ground electrode

• Extended service life, reduced electrode temperature, and improved access to air/fuel mixture

• Nickel-plated rolled threads

• Complete anti-seize and corrosion protection

• Lower ignition voltage requirement vs. other plug designs

• Reliable cold weather starts and superior operation under all driving conditions
