Review on Bosch Automotive OE 9600 Fine Wire Double Iridium Spark Plug - Single by Louis Loebis

Ordered for Prius 120,000 miles service (need to be replaced first time!). Great price combined with a discount offer. A bit tricky due to the deep cutouts for the plugs alone, and removing/replacing the igniter for the #4 plug on the right is tricky due to gap issues. But did, works great. Suggestion from a mechanic friend: get a metal anti-seize compound designed for plugs and apply it to make installation really easy (like oil) and hopefully a lot easier to remove next time too make (WAY in the future).
