MAFz

My maf is poop. I went to look for another one last night and i found a bunch, but it occured to me at the last minute before ordering that there is something weird with the numbers.

i don't wnat to get a new sized maf and have to retune again. so i'm trying to keep the same one. but i can't seem to find info about this...

My maf model is 077 133 471 KX

but! I keep finding maf numbers of 077 133 471 JX or just X

Do the last two letters mean anything? The KX and JX and X all seem to list the same vehicles, but it makes me wonder what those two letters mean?

Any ideas before I potentially order the wrong one?

Re: MAFz

can you order just the sensor to slide into the housing right? did you try finding the PN via like ECS tuning site?

i'm sure jordan knows though

Re: MAFz

usually the last letter is the revision but it looks like you have another letter after the revision letter.

Re: MAFz

It's probably your turbochargers. MAF is fine.

Re: MAFz

So the JX and KX are different?

Re: MAFz

Ah looks like they are all for the 4.2L V8 so must be the same

Re: MAFz

X as a suffix is remanufactured, to confirm. Can't help otherwise.

Wicked thanx dude

Looks like there is also G J and K. But they all seem to fit the 4.2v8. Which makes me think they are the same.
