Product codes

• OEM code: 10-M1121
• Manufacturer code: 10-M1121

Detailed technical description

This resistive spark plug cap (also referred to as plug cap / spark plug boot) uses a ceramic resistor to reduce electrical interference and support cleaner ignition operation. Resistance is 5kOhm, a common value for resistor caps.

A worn cap can lead to unstable contact, hard starting, or irregular running. Replacing it helps restore the correct connection between the ignition lead and the spark plug, while the sealed design improves protection in damp conditions.

Main features

• Integrated ceramic resistor for consistent performance
