The only I might add. If you have to replace your stock coil or coils. The nology ones are cheaper. I have nology coils on mine and some fancy smancy german wires. Whether it runs any better with them or not, I can't really say. My last dyno run was 61 rwhp. But have nothing to compare it to before so its meaningless. Besides dyno runs can vary form one day to the next with many many things altering the outcome.
