Spark plugs, wires, distributor caps and rotors break down and fail over time, due to exposure to moisture, oil, grease and under hood temperatures that can reach as much as 550 to 700 degrees. Here's what happens: Worn spark plugs cause higher voltage requirements, forcing the ignition module and coil to produce higher and higher voltages to overcome the resistance. Then replace it before you move on to the next spark plug in cylinder sequence order. Manufacturers are noting that spark plugs don’t need maintenance until 30,000 and up to 100,000 miles have been driven (the latter figure is recommended for the specifically manufactured long life spark plugs).

Spark plugs will age and as time goes by, the sharp edges wear down, and more voltage is required to bridge the gaps between the center and ground electrodes. Once your ignition wires start to wear out, it is much more difficult to deliver a good spark from the distributor or coil pack. Your check engine light comes on. The resulting load of unburned gasoline in the exhaust will jack up the operating temperature of your converter and may cause a meltdown of the converter substrate, which in turn will form a restriction or full blockage of the exhaust, literally choking your engine. Iridium spark plugs feature a fine wire center electrode that is designed to conduct electrical energy better and increase firing efficiency. These warning lights may illuminate if the spark plugs are fouled or failing, or if the spark plug wires need replacement. 4) The ability to turn off spark to a failed cylinder to limit damage to the catalyst in certain misfire conditions. Though a miss or rough running is not always caused by bad spark plugs, they can be one of the c… There always seems to be something to be concerned about underneath the hood.
