      Comments about Bosch OE Fine Wire Iridium Spark Plug:

      I put them in my car a few days ago and they work as intended. I would give them a higher rating but am asked to rate them now. They replaced a set of plugs of which were in the car for 7 months that were rated for at least 50000 miles and one failed within the first 10000. So I cannot rate the longevity of these. I have to say that anything works great when it is brand new. Time will tell if they are good or not.

          Comments about Bosch OE Fine Wire Iridium Spark Plug:

          Easy to replace the plugs on my 2008 Ford Fusion, but not sure why the gap (0.044 inch)on the Bosch plugs was smaller than what my Ford Fusion book called for (which was 0.049 to 0.53 inches).

            Dont buy into the hype of multi ground electrode spark plugs. stick with what the manufacture calls for. Replace your air filter and you will be able to see a mpg increase.

              Easy to install. Just be carefull removing the coil pack connected to the spark plug boot. Grasp it low on the boot to avoid damaging anything.i also had to unplug #4 coil pack, and leave #3 out until i place #4 in.".....".................................................................................................................................................................................................................................

                Comments about Bosch OE Fine Wire Iridium Spark Plug:

                Just bought and installed a set of these on the wife's '07 Mazda 6 with 4 cyl. The ones that were in it were the original units with 130K miles on them...OOPS! Time flies when you're not the sole driver of a vehicle and some maintenance gets overlooked.

                So I installed these and didn't tell the wife. Only took about 20 minutes since they're all accessed right on top of the engine. She ran an errand the next day and came home and commented about the car running better for some reason. It was only then that I told her I changed the plugs.

                Can't argue with a 7 year warranty either. I don't see any other manufacturer offering a warranty that long. Also, the price was cheaper than all the other iridium plugs offered.
