Newbie here. Just wanted to find out if anybody has used msd coils. I was told they make a difference in the performance. I already have a cold air kit, headers and a true dual exhaust. Love the difference from stock but was told more could be had. Any input would be great

Hey, welcome to the site. Personally, never upgraded a coil like that. I have heard that it should work in conjunction with a hotter electrical system overall.
