Eliminate high-RPM misfires and improve cold-start reliability with the NCY Performance Ignition Coil. Often referred to as a "Super Coil," this unit is engineered to deliver a significantly stronger and more consistent spark than thin factory components. By increasing the voltage delivered to the spark plug, it ensures a more complete combustion cycle—yielding crisper throttle response, a smoother idle, and a noticeable performance gain throughout the entire powerband.
Advanced Ignition Features
- High-Energy Discharge: Delivers a more powerful spark capable of bridging the gap in high-compression engines or modified "Big Bore" builds.
- Durable EPDM Boot: Includes a premium, high-tension rubber cap designed to seal out moisture and prevent vibration-induced "spark-pop" off the plug.
- Direct Plug-and-Play: Features the standard 2-pin spade connector architecture for a seamless installation on almost any small-displacement 4-stroke engine.
- Tuning Optimized: Specifically designed to work in harmony with aftermarket Performance CDIs to unlock your engine’s full RPM potential.
