Detailed technical description

This spark plug resistor cap, also known as a plug boot / resistor plug cap / ignition lead cap, connects the high-voltage ignition wire to the spark plug while reducing electrical interference through its integrated resistor.

The 5k ohm ceramic resistor supports consistent spark delivery and proper ignition operation. A worn cap can cause hard starting, misfires, hesitation under throttle, or power loss; replacing it restores proper contact and water sealing.
