The nology coil and hot wire are deffinately worth there weight and gold.The spark is far superior than stock.I suggest if yu can afford it to get it.Also save some money and do not buy from project blaster.Everytghing they sell is a rip off.Go on the web and search RJATV,send john an email stating what you want and he will save you some money.Probably 20-30 dollars cheaper then project butt blaster.IMO
