Spark plugs?????
Today I went into an auto parts store looking for delco 41-921 douoble platinum plugs, they told me they had been replaced with iridum plugs 41-101. What is the difference between Plantinum and Iridium? :?

The spelling.
Kidding! Regular plugs require to be changed about every 30-50K kms. Platinum plugs every 90K kms and Iridium plugs every 150K kms. It is just the material that the electrode is made from. Every time that the spark jumps from the electrode to the post, it takes a few minute particles with it. Iridium is incredibly resistant to this stress and just last longer. That being said....I would not want to pull the plugs out of an engine that has had the plugs in for 7 or 8 years. Can we say seized?
Hope this sheds light on it.
