The NGK TB05EMA spark plug cap delivers outstanding performance, durability, and reliability for a wide range of engines. Designed to work with spark plugs featuring a 14mm terminal nut, this cap ensures a secure fit and optimal electrical connection. Built with a 5kΩ resistor, it provides excellent noise suppression for consistent ignition performance and reduced radio frequency interference.

Manufactured from high-quality, heat-resistant materials, the TB05EMA offers superior insulation and protection against moisture, vibration, and heat — making it ideal for use in motorcycles, ATVs, small engines, and other powersports applications. Its right-angle “T-type” design allows for easy installation in tight spaces while maintaining strong mechanical grip and weather sealing.
