My opinion, stick with stock plugs and don't bother touching the coil packs. Alot of people have a common missconception that aftermarket coil packs like MSD are better for the car. In reality they produce less voltage than stock, and also aren't anywhere near as reliable. There's a reason ZZP's 8 sec drag car is still running stock coils.

You feel like spending some money, don't bother with the ignition, there's no power to be had there. Pick up an HV3 from ZZP
