I'm wondering what the deal is with the LT1 MAF's. I noticed that on the same year and model of LT1 the MAF's have different numbers on the sticker. So I am wondering which MAF's are interchangeable from 94-97. I would think that the 96 & 97 MAF would not work with a 94-95 because of OBD-II but I wanna say that I recall seeing that it didn't matter. Does anyone know if there is any difference in the MAF's between the years of 94-97?

 

They are the same. I think the biggest diff. between OBDI and OBDII is the addition of the crank sensor and the extra o2 after the cat.

 

Any will interchange, plus an LS1 MAF will too.

 

You mean the LS1 MAF is interchangeable between 98-02 not that the LS1 MAF Will work on LT1 right? Just making sure I read that right

 

No, I mean the LS1 and LT1 MAFs are the same.

 

I think in 2000, the plug changed, but there are adapters out there that will make it interchangable. I may be wrong though. I know my 99 is the same as my 95.

 

Really? I thought the LS1 MAF is a lot bigger than the LT1 MAF.

 

i thought the 98 was the same and the 99+ was bigger. i could be wrong thou..

i do know i got a maf of a 99 silverado and it was bigger than the lt1 maf..

 

My 99 LS1 is the same as my 95 LT1. I think the trucks are all different.

 

The same MAF is listed by AC-Delco from 1994-2002. It also fits many trucks, Suburbans, vans, ...

 

Hmmm no kidding... Maybe I was thinking about the Z06 MAF since it's 85mm, the stock LS1 MAF is 80mm then correct?

 

the lS1 Maf's are bigger (most, not sure what years), try a 93 MAF

.lol!!!! (93's didn't have a MAF)

 

LOL...

Well that's what I thought but then how come shoebox is finding that the same maf is used from 94-02?

 

i had investigated swaping the 98pcm for the 99pcm when i was working on my lt1 ls1 project and i did read that the maf tables were diffrent for 99+, this would mean a diffrent maf.. again i could be wrong as my info is taken off the internet and i have yet to see a actual 99z28 maf.
