Review on Bosch Automotive (6717) OE Fine Wire Platinum Spark Plug - Individual by Tyrell Christmas

I love these Platinum Plugs. . an upgrade from the old Bosch plating forks that I removed. The old spark plugs worked fine at idle but protested under load. These new version forks cured it right away. I can't remember when I installed the original kit - that's the problem with those platinum candles, they last four years. He opened a box of candles, dated them, and put them in the glove compartment. I also thread cleaned the treads and applied anti-seize to each plug. Didn't put dielectric grease on the spark plug boots, but shouldn't have had an arcing problem here in the desert.
