I will be running KPro on my 2004 S2000, and I'd like to replace the coil packs before I get a tune, as they're a bit old. I've read that there is potentially an issue with running 04-05 coil packs in an 06+ car, and vice versa. So, do I need to buy 06+ coil packs to run with my KPro, or do I stick with 04-05 coil packs?

 

stick with the stock coilpacks you currently have.
