Description

This is OEM Champion Spark plug for a Triumph TR3, TR4, TR4A, Triumph Spitfire 1962 to 1967. ***Note: These resistor spark plugs use a 5k ohm ceramic resistor in the spark plug to suppress ignition noise generated during sparking.*** Cross Ref.# 575-000, 7331, BP6HS, L87Y

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 Igntion 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.
