i'd appreciate if you give me an idea which spark plugs work best on a supercharged S2000.

thanks,

 

BKR8EIX

I use them, 1 step colder and iridium.

If anyone flames you for not using the search, its down as usual and very unreliable.

 

same thing i run in my f24c...i actually switched up for 2 runs to ngk BCPR7ES...They might be too hott of plug though.. Do a run or two on them and pull them out and if u have a purple rings on the threads there too hott of a plug. Hope this helps. DEF stick with NGK

 

Ya for boosted you definitely wana go colder. A hotter plug will greatly increase the chance of detonation in a FI application.

 

He makes a good point. Your best bet is to start with the 8's..Make sure to gap them correctly as well. Im sure there been a post about gapping the plugs for SC applications. ur gap needs to be
0.25-0.30 If im not mistaken.

 

Ya, the BRK8EIX plugs come pre gapped and its been said to be a bad idea to try to gap an iridium plug because you could damage the electrode.

 

Also look at the Denso Ik24's

Search string below:

Stay away from densos!!!!!!!! I had tons of problems with those and misfires.
BKR8EIX all the way!

 

Ok I agree with this, but haven't personally ran the denso.

So keep the .032" pre-gap then?
