NGK RC-FD1217 Ignition Cable Kit (NGK 44250)
This NGK ignition cable kit replaces ageing HT leads to restore a strong, clean spark. It helps reduce misfires, smooths idle, and maintains performance under heat and vibration. High-grade silicone jackets and noise-suppressed cores improve reliability and protect sensitive electronics.
- Reliable spark delivery for consistent combustion and smoother running
- Low-resistance, noise-suppressed cores to reduce radio and ECU interference
- High-temperature silicone insulation for long service life

Installation tips
Replace one lead at a time to keep the firing order correct. Route away from sharp edges and hot exhaust parts. Seat boots firmly on plugs and coils. A small amount of dielectric grease can help sealing and future removal. Do not pull on the cable to remove a lead – grip the boot.
The price displayed is for a single plug, please add the desired amount to your basket.
