Detailed technical description

This spark plug resistor cap (also known as spark plug cap/boot) features a 5-ohm ceramic resistor designed to support stable ignition operation. It helps maintain consistent spark performance and reduces contact-related issues that often occur with aged or cracked caps.

The sealed/waterproof design protects the connection from moisture and dirt, while the adaptable thread allows installation onto the high-tension lead. Replacing a worn cap can help prevent misfires, hard starting, and intermittent running caused by leakage or oxidation.
