In a wasted spark system, the spark plugs fire in pairs, with one plug in a cylinder on its compression stroke and the other plug in a cylinder on its exhaust stroke. The extra spark during the exhaust stroke has no effect and is thus “wasted”.
Are copper spark plugs better than platinum?
Platinum and Iridium plugs perform at a lower level than copper spark plugs, because they are less conductive and they tend to overheat. However, the overall longevity of these two types of metal is better than copper plugs. In reality, copper has the best performance of all three and the worst longevity.
How much does it cost to replace platinum spark plugs?
The cost depends on the expected life and material used on the electrode. Platinum- or iridium-tipped plugs using laser technology cost the most: as much as $25 each. You can pay between $16 and $100 for a set of spark plugs, depending on the type of plugs you need and the number of cylinders your engine has.
