I just replaced my Bosch Coil with the Blaster 2....and have a few cuts to prove it! Ha Ha... I'm really a terrible mechanic....but pretty much remove the old one and replace it with the new one. Not much room in there.
Started it up and it seem to start a little easier with less cranks and ran smoother when cold. Not a huge amount but noticeable.
What exactly is the difference between the two coils??? Blaster puts out more /stronger spark right?
