The Dragon ignition part has enhanced the startup performance of my 2016 Harley with a 2mm wire. I tested it and the results were remarkable, providing a stronger and intense spark than the stock ignition .The installation was easy as it fits perfectly in my vehicle. Its durability is also commendable and will serve for years. However, IT'S slightly expensive than other options, but the quality is worth the cost. I`d recommend Dragon 10 2Mm for all automotive enthusiasts..See full review
