I am trying to decide which would be better, the MSD blaster 2 coil and the EX Cap or the hyperground kit. Trying to see what would be worth the money. I have read the gains that the hyperground kit received and damn they were pretty strong on some, but of course a stronger spark means more efficiency. I need your guys opinion. My car only has 70,200 miles on it so I am guessing my ground is still good. No sound system really just going to upgrade interior speakers.
