I have a spare MAF too. The only problem
is that its the one with the sideways connector.
I bought it from NAPA when mine crapped out.
I drove it for about a week or two, until I found
a good used one. The calibration is a bit off on
the ones with the sideways connector causing
some drop in performance. Its OK for a daily
driver, but sucks for racing. If ya need it to keep
your car on the road, let me know.
