      Comments about NGK Iridium IX Spark Plug (DPR7EIX-9):

      The iridium plugs work really well - and last far longer than the stock plugs. Slight increase in fuel mileage and very smooth firing. The real draw on these is they last at least 2x longer than the stock-type plug. Changing plugs in a Wing is a pain, these save a lot of pain due to their longevity.

          I used these on my Yamaha V Star and they worked great,I bought a Yamaha Royal Star and put these in and noticed more performance and the bike fires up on the first 2seconds of pushing the start switch and it seemd like thee was no backfire when i downshifted I would recommend these plugs as an upgrade from the regular NGK'S

          Looked at many stores trying to find the spark plugs to fit my Honda Shadow. Found this online and pre-ordered. Were available within the next day, were the perfect fit. Would recommend this product and store to anyone looking for a high performance yet affordable spark plug.
