I just picked up the MSD power cap for my gsr but now i have to buy the blaster coil, do I need just the coil or the one the with Power Tower, resistor, terminal and boot?

 

I like the blaster coil myself, the one that has the power input on one side then a wall in the middle and the coil output on the other side. You don't need a resistor for it. MAKE SURE you hook up the wires correctly. You don't want to run it reverse polarity or you can fry it out pretty quickly.

 

how do u hook up a blaster coil without a box
