i have the msd coil pack,65,000 and still running strong,ive been down the 1/8th and 1/4 mile well over 300 times and i drive 140 miles a day and not even a bit of hesitation,was my first upgrade,but i have seen with my owns eyes the msd go bad and make our cars sounds like a fawkn subaru,seriously do the modern performance way to "300" it will get you really low 13's or even high 12's depending if you have the driver mod
