As a professional manufacturer, we offer high-quality D8TC D8EA D7ES motorcycle spark plugs, engineered for reliability and broad compatibility. These spark plugs adhere to industry standards, designed to meet the ignition needs of low-to-medium load small gasoline engines—ideal for maintenance and replacement. With customizable iron shell finishes (pearl nickel, black nickel) and ceramic colors (white, red, etc.), they combine functionality with aesthetic flexibility. Sourced from CN, they fit popular models like CG125, making them a trusted choice for riders and mechanics.
Features 12mm thread diameter, 19mm thread reach, and 18mm hex size—consistent across D8TC D8EA D7ES variants for easy installation on compatible engines.
D8TC’s medium heat range ("8") dissipates heat effectively, preventing pre-ignition or carbon buildup in varied operating conditions.
Nickel-copper alloy center electrode ensures good conductivity and stable spark generation, while alumina ceramic insulator resists high temperatures and electrical leakage.
Pearl nickel/black nickel iron shell enhances corrosion resistance, paired with wear-resistant components to extend the spark plug’s service life.
Many variants include a built-in resistor to reduce electromagnetic interference, safeguarding engine electronic components.

Yes. We offer customization options for the iron shell finishes (Pearl Nickel or Black Nickel) and ceramic body colors (White, Red, Black, Yellow, etc.) to suit different aesthetic needs.
The D8TC spark plug has a medium heat range graded "8", which effectively dissipates heat from the combustion chamber, preventing pre-ignition and reducing carbon buildup.
They are built with a nickel-copper alloy center electrode for excellent conductivity and stable sparks, paired with high-grade alumina ceramic insulators to resist extreme heat and electrical leakage.
Yes, many variants come equipped with a built-in resistor designed to suppress electromagnetic interference (EMI), helping to protect sensitive engine electronic systems.
