I was just wondering, i rebuilt my engine with lower compression 8.5:1, and plan on runnin 12 psi on the street, and 25 psi on the track. I was thinking that NGK plugs (non-platnium), with a smaller gap, prob the stock gap for the GST. Let me know what you all have tried/tested.

Regular NGK's are fine, one heat range colder(7's) I just leave them gapped at .035, works for me. Stage IV adds the fuel stuff like the DFI, are you running that ? Just seein how you liked the DFI. -- Brad Rickard 98 GS HRC Stage V (nuff said)
