Well, I plan on adding either a plenum spacer, or a Crawford plenum, so @ the same time I should replace the plugs

Anyone know, off by had, if the NGK Iridiums are pre-gapped?

Yes they are pre-gapped- just goto your local auto-part store and ask for plugs on your Z and tell them you want the Iridiums.

NA = NKG LFR5A-11. These are copper.

For FI, you'd want one step colder. A "6" instead of a "5" in the part number.

not to be negative or anything, but your going to regret buying the megan headers. the term "you get what you pay for" works well for those, you cheap bastard lol.
