NGK Motorcycle Spark Plug Cover - SD05FM (8392)

The NGK Motorcycle Spark Plug Cover - SD05FM (8392) is a precision-engineered resistor caps designed to deliver perfect ignition noise suppression across the full frequency range without reducing engine performance. Built around a durable ceramic resistor element and a tough phenolic resin body, these covers provide long-term, stable resistance and outstanding reliability even under high heat and high voltage. Moisture-sealing rubber liners at both ends prevent electrical leakage, while vibration-resistant construction ensures consistent contact between the spark plug and high-tension lead.

Ideal for modern motorcycles that must meet strict noise regulations, NGK spark plug covers maintain full power output and service life when used alone or in combination with NGK resistor spark plugs.

Benefits:

• Excellent ignition noise suppression across all frequencies without loss of engine performance
• Durable ceramic resistor element for stable resistance and long service life
• Robust phenolic resin body and rugged rubber components withstand high temperature and high voltage
• Heat-press, vibration-resistant construction maintains secure connection to HT cable
• Special rubber liners at both ends help prevent moisture ingress and electrical leakage
• Designed to help motorcycles meet current noise-suppression legislation and standards
• Compatible with NGK resistor spark plugs for optimal ignition and reliability
