What are the production processes for spark plug caps?
At room temperature, use a connecting piece to securely fasten the resistor cap and self-tapping screw together, forming the screw assembly. Component assembly: At room temperature, sequentially insert the spring, resistor, and conductive cap into the main body, then finally screw the conductive cap into the main tube of the body to complete the assembly.

The spark plug cap (ignition coil boot) is a critical component that connects the ignition coil to the spark plug, serving key functions such as: Located between the ignition coil and the spark plug, it’s made from high-temperature-resistant materials like silicone or rubber, designed to efficiently transmit the high-voltage current to the spark plug—ensuring that the ignition energy is released effectively.

What are the symptoms of a faulty spark plug cap?
A damaged spark plug high-voltage cap can cause the ignition system to malfunction, particularly in cold weather conditions when the air-fuel mixture has poor volatility. If the ignition energy is insufficient, this significantly increases the likelihood of repeated failed starts or even complete inability to start the engine.
