Quote from: Shifrty1 on January 06, 2014, 10:32:27 AMGood morning all! I was looking at summit racings website and stumbled upon some msd and accel coil packs for my 2013 sho. im considering taking this step along with colder iridium plugs. I know one of the few advantages i may gain is a bit better mileage and possible quicker throttle response. has anyone entertained this mod?
