NGK Racing HT Coil Spark Plug Cap Cover [x1] – Hyosung RT125 RX125 MS3-250

Description

Why upgrade your HT Coil Spark Plug Cap?
Spark plugs are just as essential as your tyres — your bike won’t go far without either! The HT Coil Spark Plug Cap acts as a vital link between your ignition coil and spark plug, ensuring a reliable and consistent electrical flow even when your engine runs hot. Standard OEM caps are prone to wear, which can lead to performance issues.

Common symptoms of faulty OEM HT Caps include:

• Engine surges or jerks during hotter running conditions
• Misfiring felt between 6,000 – 9,000 RPM
• Unsteady or bouncing RPM needle on the dashboard
• Change in exhaust tone — often boggy or uneven
• Cracking or deterioration of insulating materials over time
