C7HSA Motorcycle Spark Plug

As the "gold standard" for small-displacement motorcycle ignition systems, the Max Trading C7HSA Motorcycle Spark Plug features a precisely designed cold-type heat rating and superior pressure resistance.

The Max Trading C7HSA is more than just a part number; it represents a rigorous standard of precision engineering. Its model code explains its excellent compatibility: "C" represents the M10 x 1.0 thread specification, matching the cylinder head interface of small-displacement engines; the "7" heat rating is a cold-type design, ensuring excellent heat dissipation even under high-load operation.

Core Technologies and Application Expansion (Technical Highlights)

1. Performance under Extreme Conditions

The C7HSA Motorcycle Spark Plug operates in extremely harsh environments. Through optimized design, Max Trading ensures that its core components can withstand peak combustion chamber pressures of up to 10 MPa.

High-Temperature Resistance: The center electrode maintains stable electrical performance at extremely high temperatures of 600°C to 800°C.

Electromagnetic Interference Resistance: The built-in "S" grade resistor structure effectively protects vehicle electronic equipment from ignition electromagnetic interference.

2. Economic Benefits from Precise Ignition

Efficient ignition not only improves power response but also significantly reduces fuel consumption.

Stable Idling: Reduces the probability of stalling during cold starts.

Efficient Combustion: The outstanding insulator design ("H" designation) optimizes the flame kernel propagation speed, allowing for complete combustion of the combustible mixture.

Core structure analysis

Electrode system: using a Φ 2.5mm center electrode (nickel copper alloy) and side electrodes, with a copper core core to enhance thermal conductivity and a nickel alloy outer layer to enhance wear resistance, capable of withstanding frequent arc erosion caused by ignition;

Insulation system: 95% alumina ceramic insulator is selected, with a high voltage resistance of over 30000V. The protruding skirt design (marked with "H") can quickly raise the temperature to self-cleaning temperature (600 ℃), reducing carbon deposition;

Sealing structure: Glass sealant is used to fill the gap between the shell and the insulator, and copper gaskets are provided at the threads to prevent high-temperature gas leakage.

Typical compatible vehicle models include

Bent beam vehicles: Haojue HJ110-E, Construction Yamaha JYM110, Wuyang Honda Fengying 125-S, etc;

Scooter: Qingqi Suzuki UU125, Jialing JH125T, Lifan LF125T, etc;

Cross cycling: entry-level models such as Zongshen 110 and Dayang 125.

The engines of this type of vehicle are mostly designed with low compression ratios (8.5:1-9.5:1) and low speeds. The high calorific value of C7HSA can adapt to its heat dissipation needs, avoiding carbon buildup during low-speed driving or overheating during high-speed operation.

Max Trading's spark plugs accurately cover countries in different regions

1. Southeast Asia/South Asia markets: Focus on 100-150cc economical commuter motorcycles, prefer nickel alloy spark plugs suitable for Honda CB series, Suzuki Gixxer and other models, with a unit price controlled at 8-15 US dollars, and able to withstand high temperature and high humidity environments of 35-48 ℃, with a service life of more than 15000 kilometers;

2. European/North American markets: Focusing on mid to high end vehicle models and modification markets, BMW K series, Harley Davidson Touring and other models account for over 60% of the compatible models, emphasizing CE and DOT certification. The demand for iridium and platinum spark plugs is prominent, pursuing a long lifespan of over 25000 kilometers and stable ignition performance, with a unit price of up to 30-65 US dollars;

3. Latin American/Middle Eastern markets: Balancing cost-effectiveness and durability, in response to the characteristics of frequent sandstorms and large fluctuations in oil quality in the local area, the anti corrosion ability of spark plug electrodes and the sealing performance of ceramic insulators are strengthened, and oil resistant spark plugs for tricycles are more favored.
