    E3 Spark Plugs Installed

    After watching some dyno #'s from HorsePower TV... I decided to do some research and found this article:

    I'm not entirely certain it makes much of a performance difference, but their emissions tests seem to be sound - so at the very least my car is now running cleaner

    Link to E3 - http://www.e3sparkplugs.com/technology.htm

    E3 part number for XLR-V 4.4L - "E3.53"

    Videos - http://www.e3sparkplugs.com/mediacenter.php (the 2nd one is the one I saw on TV).













    Old plug - after 17k miles:

    Since they are new sparkplugs; they will seem to make the XLR-V run like new since they plugs are new. You need to wait to see the actual difference; 500 miles should break in the sparkplugs to see if you are either getting better mileage or/an better performance.

    Thats probably a very good point.

    But in the testing (if you read/watch the links I posted) you'll see that all their testing was done with new plugs.
