Product overview

Core functionalities

Applicable scenarios

Unique advantages

  • Reliable Ignition: Designed to ignite fuel-air mixtures in internal combustion engines through a spark between nickel electrodes, ensuring efficient combustion in motorcycle engines (e.g., 70cc models).
  • Durability & Longevity: Constructed with nickel-based electrodes and a ceramic insulator, offering corrosion resistance and reduced fouling for extended service life under high-temperature conditions.

Key features

  • 1. Advanced Material Technology

    • With an iridium/platinum center electrode and nickel alloy ground electrode, achieve superior resistance to wear and corrosion compared to traditional copper-based spark plugs*. The ceramic insulator ensures reliable electrical isolation even in extreme engine conditions.

  • 2. Precision-Engineered Design

    • With a customizable spark gap and universal threaded mounting, optimize ignition timing for high-performance 70cc motorcycle engines like the A7TC and B8TC. This design reduces misfires and improves fuel efficiency compared to non-adjustable models*.

  • 3. Enhanced Performance Parameters

    • Deliver consistent high-voltage sparks at elevated RPMs, enabling faster acceleration and smoother idling. The noble metal center electrode maintains efficiency 15-20% longer than standard spark plugs under heavy-duty use*.

  • 4. Scenario-Specific Adaptability

    • Engineered for motorcycles, this spark plug balances reliability for daily commutes and durability for off-road adventures. Its corrosion-resistant nickel components ensure stable performance in harsh environments like rain or dust*.

  • 5. Compliance with Industry Standards

    • Constructed with materials meeting automotive safety and emission standards, ensuring compatibility with modern engine designs and regulatory requirements.
