    How is it wasted spark? 99 and up 4.6L use the coil on plug system. I don't see how much more efficient it can get.

    And considering my above comment, his car doesn't have plug wires.

    not bashing, but its waste spark, not wasted. not only does the plug fire on the combustion stroke; like dallas said, it fires on the exhaust stroke while the valve is open to burn off any "waste" in the cylinder.
