    Comments about NGK Iridium IX Spark Plug (DR9EIX):

    I did a valve adjustment on my 2008 NINJA 500 at approx 52K Miles, and changed the Air Filter which was gross (first time changed). Decided to try iridium Spark Plug. Found the DR9EIX at Advance Auto.

    After all the above, the idle speed was higher and I had to adjust idle control back a couple hundred RPM (it was idling better). It seemed to start easier. My gas mileage is now 60 MPG vs mid 50s before (maybe spark plug, maybe air filter, maybe valve adjustment). All done at same time.

    Depending on where you look - Iridium Spark Plugs are better or not better. Mostly, I think better. Cannot say about durability after only 6 K Miles.
