4.5 (58) at The Green Spark Plug Company
£13.36
The NGK ZFR5LP-13G is a Laser Platinum spark plug and an original-equipment long-life plug.
It has platinum on both the centre and ground electrodes. Platinum’s high melting point and resistance to erosion mean the electrode gap barely grows over the service interval, helping the plug keep its factory ignition performance until the scheduled change.
It is designed as a direct replacement where the manufacturer specifies part number 7781, especially for engines with distributorless or waste-spark ignition, where the ground electrode wears as fast as the centre electrode.
