    Comments about Bosch OE Fine Wire Platinum Spark Plug:

    Perfect Replacement for Platinum OEM Plugs. Bosch makes great products. Their plugs come with a better warranty than other manufacturers. To make things easier in the future, I would recommend using some Anti-Seize on the threads, to make future removal easier. I had to be very careful when removing the OEM plugs, so as to not brake them, since they were very seized. These replaced OEM plugs after about 130,000 miles. I couldn't ask for better performance than these provide. I've already seen an increase in MPG.

        Had to replace 3 of these in a year due to either hairline cracks in the ceramic insulator or total crumbling of the insulator. Very fragile.

            Comments about Bosch OE Fine Wire Platinum Spark Plug:

            Great replacement plug for my 2001 Town and Country Minivan. Replaced extremely old Champion plus with these new Bosch plugs. Installation of the plugs was very simple and straight forward. These new plugs threaded in very nicely and seated perfectly. I was a little worried after a little struggle getting the old ones out, but in the end I was glad I chose these plugs as replacements. True to Bosch quality, these pre-gapped plugs were indeed gapped to spec. I also included a wire replacement during my plug swap due to 150k on original wires and a very rough idle. Now the old girl is purring beautifully. The rough idle is gone and the gas mileage is up. Couldn't be happier.
