Description
These are the best spark plugs for your British car. Champions are OE for all British cars and resist plug fouling better than other brands of plugs. Fits: Austin Healey BJ7, BJ8,MG Midget 1500, Triumph Spitfire 1968 to 1980, Triumph GT6, Triumph TR7, Jaguar XK120,XK140,XK150, Jaguar E-Type 1961 to 1971, XJ6 1969 to 1987. ***Note: These resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking.*** Cross Ref.# 071-711, 415, 7832, 860-051, BP5ES, n12Y
Champion strongly recommends using resistor spark plugs in any vehicle that uses on-board computer systems to monitor or control engine performance. This is because resistor spark plugs reduce electromagnetic interference with on-board electronics. Example Pertonrix Ignition Systems
They are also recommended on any vehicle that has other on-board electronic systems such as engine-management computers, two-way radios, GPS systems, depth finders or whenever recommended by the manufacturer.
In fact, using a non-resistor plug in certain applications can actually cause the engine to suffer undesirable side effects such as an erratic idle, high-rpm misfire, engine run-on, power drop off at certain rpm levels and abnormal combustion.
Champion Copper Plus® spark plug technology began as an automotive OE plug and the technology has been passed down to the aftermarket. The nickel alloy center and ground electrode provide great wear characteristics and the extrusion of copper into the center electrode allows for an increase in conductivity and heat control. Champion Copper Plus® spark plugs are a great choice for OE-replacement on older automotive engines.
