I have MSD 8.5mm Ignition Wires.

 

No need. The stock ignition system is powerful enough to power a stock and even moderately modified GSR motor.

 

To date, I have not been able to find an ignition coil that is a direct install without having to make several modifications. The SS MDI did not work on my 1999 Accord EX VTEC. The stock coil has 3 wires to it. The aftermarket coils only have place for 2 wires.
