NGK RC-HD1202 Ignition Cable Kit (NGK 5506)
This NGK ignition cable kit restores a strong, consistent spark. It replaces aged or cracked leads that can cause misfires, rough running, or poor fuel economy. Built to OE standards for dependable performance, it uses quality materials to handle heat, vibration, and moisture under the bonnet.
The cables use resistor cores to control electrical noise (RFI). This helps protect sensitive electronics like the ECU and sensors. Silicone boots and jackets seal well on the coil and plugs, reducing arcing and keeping contaminants out.
Expect smooth starting, stable idle, and cleaner combustion. It is a direct-fit kit for specific vehicles and engine layouts. Use our vehicle lookup or check the Vehicle Fitment tab to confirm it suits your car.
