NGK WR5IX 7510 Spark Plug Iridium IX

£12.21
The NGK PFR6W-TG 5547 is a platinum 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 this part number, especially for engines with distributorless or waste-spark ignition. The plug is described as an original-equipment long-life plug; its platinum electrodes resist erosion, helping the electrode gap barely grow over the service interval and maintain factory ignition performance until the scheduled change.
