Lowest price we found
£2.82
The Champion RC9YCC Copper Plus is a spark plug with a copper core and nickel-alloy centre electrode. It has a 14 mm diameter and the part number OE002.
The copper core draws heat away from the tip. The plug is described as tolerating a range of driving conditions without fouling or overheating, and as easy to gap and inspect. Its construction is suited to engines running rich or being started infrequently.
Copper Plus types are presented as replacement plugs for classic cars, motorcycles, marine and garden engines originally fitted with Champion, and as service plugs on many later vehicles. The heat value converted to the NGK scale is a comparison guide; cross-references can differ by half a heat range, and values may have shifted over time where no direct replacement exists. Check the recommendation for the vehicle.
