The H.T. Coil is a genuine spare part manufactured by Piaggio so you have peace of mind the H.T. Coil part being sold by Motorcycle Spare Parts is both original and new.
The H.T. Coil, with manufacturer part number 638678, is an integral part of an automobile's ignition system, designed for use in several automotive brands, including Aprilia, Derbi, Moto Guzzi, Vespa, Gilera, and Piaggio. The term "H.T." stands for High Tension, which clearly describes the function of this auto part. The purpose of a H.T. Coil is to generate the high voltage necessary to create an electric spark in the spark plugs to ignite the fuel in the engine.
This coil works by utilizing the principle of electromagnetic induction. It is basically a transformer that converts the vehicle's low-voltage power to the high-voltage required to ignite the air-fuel mixture within the combustion chambers. Without a functioning H.T. Coil, your vehicle would fail to start.
The specific part number, 638678, allows for accurate identification and sourcing of the part, ensuring it is a suitable replacement for the existing component in the mentioned brands of vehicles. This precise fit reduces the risk of improper installation or performance issues due to incompatible parts.
As an OEM (Original Equipment Manufacturer) replacement part, the 638678 H.T. Coil is designed to the exact standards and specifications as the original component. This means it provides the same quality, performance, and safety features as the part that was initially installed in the vehicle at the factory.
It's important to remember that while the H.T. Coil is a durable component, like all automotive parts, it can wear out over time or fail unexpectedly, requiring replacement. Regular checks and maintenance of the ignition system can prevent sudden coil failure and improve the overall performance of your vehicle.
