Unbranded F01R00A039 4 Ignition Coils sku-17685113448

Unbranded model F01R00A039, sku-17685113448, is a 4-piece ignition coil set in Engine & Powertrain Replacement Parts. Part number DQ9021D is listed for Geely Emgrand 1.5L and Emgrand EC7, Vision SC7, Seaview and GC7 vehicles with 4-cylinder engines. The coils convert battery voltage to the voltage needed by spark plugs.

The stated design uses a high-purity copper winding and layered insulation, with resistance of ≤ 0.5Ω, a claimed 30% improvement in energy conversion and output up to 40000 volts. Its magnetic circuit is described as reducing eddy current losses and responding 20% faster than traditional coils.

Sealed epoxy encapsulation helps keep out moisture and oil; the stated operating range is -40°C to 180°C, with a claimed 50% improvement in vibration resistance. The housing combines aluminum alloy and heat-resistant plastic, and the stated lifespan exceeds 100000 kilometers.

The listing also describes pen-style and modular configurations for naturally aspirated, turbocharged and hybrid systems, along with support for start-stop operation and cold starts. Its factory-style plug connection has a keyed buckle; professional installation is recommended to ensure a seal.

The listing cites testing to ISO 9001 and SAE J2526, 150000 high-voltage discharge checks and a 24-month warranty. Suggested inspection or replacement is at 80000 to 100000 kilometers, or if acceleration weakens or starting becomes difficult. It recommends pairing the coils with high-performance spark plugs.
