Restore crisp throttle response, clean combustion cycles, and reliable cold-weather starting with the Universal Parts CN250 Ignition Coil. Engineered as a high-output, factory-spec replacement, this complete high-tension coil setup steps up your primary voltage to deliver a continuous, hot spark arc across the plug gap—preventing top-end spark blow-out and mid-range engine hesitation.
Because ignition coils are subjected to intense thermal expansion and engine vibration, internal copper windings can break down over time, leading to weak spark conditions, rough idling, or a complete loss of ignition fire.
Product Features
- High-Voltage Primary Core: Optimizes primary-to-secondary winding ratios to maximize spark energy and overall combustion efficiency.
- Heavy-Duty Molded Cap: Arrives equipped with an insulated spark plug boot cap designed to seal tightly against moisture, dirt, and oil debris.
- Flexible Wire Jacket: Thick silicone-insulated high-tension lead isolates current and prevents voltage grounding or arcing against the metal frame.
- Standard Ground Configuration: Features standard spade terminal tabs for a quick, direct plug-and-play tie-in to your stock wiring loom.
Technical Specifications
- Wire Length (High-Tension Lead): 14 Inches
- Overall Structural Length: 20 Inches
- Engine Configuration: 4-Stroke Liquid-Cooled 250cc (172mm Style Layout)
- Mounting Profile: Single standard chassis ground mounting bolt hole
- SKU Reference: 180-156

Tuning Mechanic's Advice: When installing your new coil, ensure the metal mounting tab makes direct, clean contact with the metal frame of the vehicle. A rusty or painted ground point will restrict primary voltage delivery, resulting in a weak spark. We recommend applying a small bead of dielectric grease inside the plug boot cap to preserve the secondary seal against water intrusion.
