Any consensus from everyone regarding where to get the best price for ordering a strong MAF?

The weak MAF typically does not start acting up until it starts getting hit with increased air flow. Just an air intake usually won't set it off but add a scoop and/or a ported throttle body and you will likely see some sluggishness, surging and bucking.

One of the cai makers discovered the lack of expected performance... tracked it down to the maf type. I have a spare strong one.... if anyone is interested... pm me

tramtwo posted this on the go

Ok, so lets ignore all vendors for a minute. If i went to my local dealer to pay dealer price there is a chance i may get a weak MAF sensor? or the stronger MAF? These weak MAF are still on the shelves?

Of course man.

There's nothing wrong with a 'weak' MAF sensor. The term 'weak' is given to the MAF because it's not as good when you're trying to build/tune a car.

The 'weak' sensor still operates within GM specification on a STOCK car. It's only when you start adding items like cold air intakes, "air scoops", ported throttle bodies or other modifications involving ramming more air into your engine that makes the 'WEAK' sensor an issue.

GM uses two suppliers for MAF sensors. They have done it from day one and continue to this day. The units from one of the suppliers do not have the same resistance levels as the other. They are within factory spec, so GM has no problem with them, but they do not like increased air flow which causes driveability and performance issues. We hand pick only "strong" MAF sensors to put on our shelf but the "weak" sensors are in the supply and still being installed in new cars on the assembly line. It is a crap shoot.

Give the article linked to earlier in the thread for a more detailed explanation.

Thanks for explanation Chase. I'm going to check mine out when I take it out of storage.

So is it safe to say that mine is the "weak" type with the P being the only letter in the window? Or am I looking at the wrong place?

My MAF doesnt look anything like that. Is that for a V6?

Yes. I looked at the pic from the post previously and seen mine looked nothing like it! Figured I could get some answers to why they're different and now why yours would be different too?...

Still would like to know if mine falls into the weak category...

Exactly. Just a single letter.
