What kind of spark plugs would be the best for a S2000 with intake, and exhaust? Also what spark plug wires would be best and what grounding kit would be best? Thanks

 

Grounding kits don't do Shit and the stock plug wires are very good, Plugs you could upgrade to Denso Iridiums if you really want to do something to your car! I still recommend a track day to learn how to drive that bad boy

 

I went to the track in Gainsville with the car club at my school. I suck but thats to be expected for first time. I did not spin out or anything but thats because I did not go fast enough. so Densos if I plan on doing more aftermarket and what kind of plugs if I dont plan on doing anything els aftermarket wise?

 

We don't actually have "plug wires" in the traditional sense. Each plug has its own coilpack sitting on top of it.
It says you have an '04. Being that it is so new, your stock plugs do just fine. If you go F.I., then maybe you should consider other plugs (and a smaller gap).
