Jaguar XJ8 Replacement Spark Plugs Information

In internal combustion engines, compressed fuels like aerosol or gas are ignited by means of a spark plug. The functioning of a spark plug is quite simple. Just like electricity produced through lightning, spark plugs ignite electricity between a gap inside the engine. High voltage is needed for the electricity to travel between these gaps to generate the sparks. The voltage should be ideally between 40,000 to 100,000 volts. Spark plugs also need to be constructed delicately as they have to stand extreme heat and pressure inside the cylinder. Each automaker will select specific spark plugs for their cars. Some cars with high and extreme performance generate high energy, thereby producing more electricity. Such cars will need colder spark plugs. The Jaguar will use supercharged V8 Jaguar XJ8 spark plugs. Colder spark plugs will have more spark area thus allowing the engines to run cooler. Always choose the right kind of spark plug for your vehicle. Wrong types of spark plugs could ignite the fuel before the spark fires, causing damage to the vehicle. You should also check the level of coil decay of the spark plug regularly. Sometimes the cover of the plug will come off and the coils will be damaged. Always buy OE certified parts to avoid these troubles.
