Default MAF sensor

What replacement maf sensor would you recommend to purchase?
They're anywhere from $30 to $200 company dependant?

Delphi (AF10043 for my '02) ~$80. You didn't mention what year your car is. Some of the earlier models have a different connector.

I tried a cheap one and it split in half at the seem. It worked otherwise.

Thanks Rob 😉. It's an 2004. Actually, Advance Auto Parts, for instance, say AF10043 doesn't fit my vehicle. It has that mesh grill too.. Mine doesn't. 🤔.
Where did you purchase it from?

I think I got mine from Amazon. I have seen better deals on eBay (make sure it is Delphy brand and not a generic). It fits your car. The Z06 didn't have the screen. You can cut the screen off if you want. There were a lot of threads where engineers and techs argued over weather there was any benefit to having the screen or not. Personally I kept it as a safety net and for reducing turbulence (if that is a real thing).

You shouldn't have any problems with this part number.

I double checked. The one I mentioned will work fine. The only difference is the screen.
Apparently it cost $100 extra to get one without a screen. I'm using it on a LS6 engine and it works fine.

Thanks buddy for all your help. 👏. Is yours a Z?
I'll keep the screen as well I think. Found the Delphi one for $75 on Ebay.
I wonder if my 2004 Z06 needs less interference for more cfm/sqft of air in our application, hence no screen originally. Maybe it is better without. Not that we'd probably notice through our butt dynos. 🙄

Mine is a coupe with a Z engine and C6Z suspension. It has all the Z options but with A4 trans, targa top and hatch. I built it.
You can search about the screen thing but that argument seems like it never came to a head. Some say it is restrictive and others say it reduces turbulence.

Will I need a retune/recalibration of PCM going from descreened MAF to screened MAF?

No! If there is a change in flow it would be almost undetectable. The PCM can adapt a lot more than any change that screen could possibly make.

If you are deeply concerned you could just remove the screen. The filament on the MAF is fragile so I would be cautious if you do this.

Thanks Rob. Figured as much. I'd never tamper with the screen... Not worth it.

Thanks for the offer buddy. Is it new? Screenless?
I just cleaned my current Screenless one. If code reappears I'll contact you. 😉

Thanks. That's exactly the one I wss looking for. The screenless. The one WITH screen shows fit for Silverado 🤔.
Question is, can you trust remanufactured?
And what's "Plus core:$50" mean?
