Thread: What would be better

So right now im running cheap 7mm spark plug wire and im pretty sure its the cause of my sputtering and misfire ...my question would a msd coil or igniton system be better than just upgrading to ngk 7mm or an 8mm wire thats on the market just wondering any info will be appreciated

(Can't find the exact thread, but the stock ignition coil is good for 500hp, but a freshening up with new OEM never hurts either)

All the info you need.

Thanks much
