NGK WR5IX 7510 Spark Plug Iridium IX

Lowest price we found
£11.13
The NGK PFR6U-11G is a spark plug in the NGK Laser Platinum range, with platinum on both the centre and ground electrodes.
It is designed as a direct replacement where the manufacturer specifies part number 5874, especially for engines with distributorless or waste-spark ignition. 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.
