      Comments about NGK Iridium IX Spark Plug:

      NGK stands out as a top brand from spark plugs. I purchased these as an ungrade / replacement for the original Champions spark plugs in a 1995 Ford Mustang Base Coupe (V6.) If you know your vehicle well, you almost immediately take note when things operate or run better. Immediately noted much smoother ignition start and idle and certainly while driving the engine now hits faster speeds are lower rpms thanks to all spark plugs firing correctly. I would recommend upgrading spark plugs for any vehicle, so I highly recommend the NGK IX iridium plugs!

          These plugs are nice! Couldnt decide whether to use the stock plugs or aftermarket on my 2010 Ford Mustang....but I am glad I went with these. (Gap was off a little but was easy to fix)

          I highly recommend them!
