NGK spark plug cap TB05EM 90° silicon

Resistor covers may be required for power sport applications when spark plugs alone don't provide sufficient noise suppression.

Designed to reduce electro magnetic interference and radio frequency interference, which can interfere with electronic ignition components, causing misfires and poor engine performance.

• Highly durable phenolic resin and epdm rubber
• Ceramic resistors ensure optimum performance and reliability
• Built to withstand extreme heat and vibration
• Prevents flashover
• Ensures optimal service life and performance
• Suitable for: 14 mm / large nipple
