they are sold for each sensor, they all rope into the same harness.

i got a maf and iat pigtail off ebay when i first got my car. like 10 bucks each.

from these guys, everything they sell is pretty much LS stuff, but PM them they will make anything with a stock plug on the end. o2 extentions too.
