Difference is materials used inside them, alot of it comes down to user preference, platinum the material itself is expensive and therefore makes the platinum plugs more expensive, we use iridium plugs on our cars because the price is more affordable, the spark is more consistent, and they last longer. Double platinum usually comes on the car from the factory.
