The previous owner installed the Stillen cold air intakes.. I was wondering if I needed to run a "hotter" spark plug with the cold air intakes?

I'll follow this post and add any comments that might be helpful if I get mine figured out. Like the others have said, it's a pretty vague code to track down!!
