NGK WR5IX 7510 Spark Plug Iridium IX

Lowest price we found
£75.45
The Champion RW80PP double platinum spark plug is discontinued and no longer manufactured. It has platinum on both the centre and ground electrodes, for distributorless and waste-spark ignition systems, where reverse polarity can wear the ground electrode as quickly as the centre electrode.
With platinum on both electrodes, the gap remains stable for the full manufacturer service interval. Fit it as a direct replacement where this Champion part number is specified as original equipment.
