Review on NGK (93618) SIKR9A7 Iridium Spark Plug with Laser Technology by Montez Parson

later Do your research. It seems the difference between this and the one that comes with your dart (1.4 in my case) is that the old ones say "Mopar". They are manufactured by NGK and sold to NGK dealers. In short, they are PERFECT at darts. I just replaced mine after developing a bad misfire for over 2k. At first I was outraged that someone didn't make them when they were needed (30,000 plugs) until I read countless stories about dealer supplies being long on order and a typical setup costing around $400. If you don't have any technical knowledge, these plugs and about an hour's time, this is far from being such an effort. The only problem I had with my transaction, and it's not NGK's fault at all, it's Amazon's: They came in a folded piece of cardboard with nothing to protect them from being dropped or damaged in transit to become. glad to say they did but it annoyed them that they are so careless with potters.
