NGK's gap depends on na or FI. Normally .060 for na.

Just put a set of AC Delco Iridium plugs in and the car runs great! They come gapped at .040 and should not be adjusted.

As I understand it, proper gap is a function of the type of plug and the compression ratio and hp you are making. Try this link for some good info. Spark Plug Info

What's the diff (benefit) of having a gap of .040 vs NGK's .060?
