Frequently Asked Questions
Q: What thread sizes does this motorcycle spark plug cap fit?
A: This spark plug cap resistor cover is designed to fit spark plugs with 10mm and 12mm thread diameters, making it compatible with a broad range of cub and underbone motorcycle models.
Q: What does the 102-degree angle mean for a spark plug cap?
A: The 102-degree angle refers to the orientation of the cap relative to the spark plug. This angled design makes it easier to install in tight engine bays where a straight cap may not fit comfortably, ensuring a secure connection without bending or straining the ignition wire.
Q: Does this spark plug cap include a built-in resistor?
A: Yes. This cap features a built-in resistor within its resin structure, which helps suppress electrical interference and ensures a consistent, efficient spark for your motorcycle's ignition system.
Q: How does the rubber seal protect my motorcycle's ignition system?
A: The rubber components at both ends of the cap create a tight moisture-proof seal around the spark plug. This prevents water, humidity, and road debris from entering the ignition connection, reducing the risk of electrical leakage and maintaining dependable performance.
