      Comments about NGK Iridium Ix Spark Plug (BPR5EIX):

      I read about using Iridium spark plugs to replace the standard nickel plugs in small engines to improve the efficiency. I installed this plug in a Honda GX390 powered snow blower to replace the stock NGK BPR5ES nickel spark plug. The engine ran good before the plug change and now seem to run a little better. It starts during the first pull of the starting rope and the exhaust sounds a little deeper. I don't have long term run info yet but will try to update this review with my findings after the winter.

        Comments about NGK Iridium Ix Spark Plug (BPR5EIX):

        Awesome spark plug!! I had to gap it but not by much. Be careful not to gap incorrectly. There is a proper way to gap any spark plug and that requires not to pull up on the gapping tool on the electrode. The electrode is very delicate. NGK is the way to go especially if you get the Iridium IX kind. The plug I replaced was an E3 spark plug and it used more fuel than the new NGK BPR5EIX spark plug. I now can do my lawn in 2 tanks instead of 3 tanks. Don't get E3's they are junk. You have to tune accordingly which means a little richer which uses more fuel. It goes on a John Deere JX75 lawnmower with the Kawasaki FC150V. I really like the performance with the new plug. There wasn't much power difference but there was less engine vibrations and smoother idling and power up though.
