Treadstone has them as well.

I have one of these with my LS3/7 stayle Maf on my procharged 01.
The screen will help straighten airflow and allows the maf to have better readings.

Mine is a 2001 as well. 2001 models HAVE a screen in the maf. There have been people who have removed the screen for that couple extra ponies BUT when its time to upgrade from the stock airbox to the Blackwing, Haltech,VR,etc., then the codes start. If you have the screen in your maf with just a Blackwing and no other mods, your problem more than likely is an air leak where the clamps connect. you have to make sure that they are tight. If you have a screenless maf and you ahve the old screen you can reinstall it but you have to make sure its as tight as oem. Otherwise, get a Haltech honeycomb screen for about $35,(there is one available on the parts forum right now), and when the budget allows, get yourself a USED Diablosport programmer UNLOCKED specifically for a 2001 ZO6 (usually btwn $100-150) upload the performance tune, good for about 20 hp. This can be your temporary mod until you decide to get a professional tune down the road. For added performance you can also go with the shroud mod for cold air. I started my mods this way and guess what.....NO CODES,NO WATER ISSUES,COOLER ENGINE TEMPS,BETTER GAS MILEAGE!! AND MORE POWER!!! MORE AIR=MORE POWER!! AND CHEAP!!

Hey Guys, I checked and cleared the code thru the DIC last night. I also tightened up all of the clamps. It sounded like there may have been a slight leak before doing that. I will drive her Friday and see if the engine light comes on again. Thanks for the advice!

I've seen MAF screens suggested by dozens of people in various different threads, so I'm not picking on anyone specifically, but...
If the purpose of adding the CAI was to increase power, then why would you turn around and add an obstruction to the air inlet afterward? It doesn't make any sense to me. If you can't afford a dyno tune, I say either get a mail-order tune, or just put your stock intake back on. You can even remove the cover from the stock intake box for added airflow without needing a MAF screen. Just my 2 cents.

AND i didnt realize you had a '01, it should have a screen (unless it was removed)... the haltech does have larger openings so it may be a better screen if you do deciede you want to "open it up" a little more.

If you have seen the Haltech Screens you will know it doesnt make much of a restriction if any... Also i would think you would get a more accurate reading from the maf to actually give more accurate adjustments from the ECU resulting in more consistant power/drivability.. just my .02

I'm looking at the GM, Halltech, and Treadstone screens, and all I see are restrictions. There's a reason GM did away with them in 02, and it's pretty obvious to me. The Halltech screen easily blocks at least 10% of the surface area of the air path. If I wanted increased laminar flow, I'd relocate my MAF to right in front of the TB, leaving more distance between it and the air filter.

The screen straightens laminar flow, therefore no codes. Without the screen the incoming air is "irratic" therefore you'll get codes. Moving the MAF to another location won't make any difference, you'll still get codes. The 02-04 models had the screen removed and an modified airbox but restricted enough to not throw codes. Change the oem airbox to an aftermarket CAI, using the oem MAF, here's the codes. No matter what brand screen is used, it's not going to leave enough hp on the table where it's worth the car buckling,stumbling, and throwing codes not having a screen.The C6 Z has the screened MAF, and with 505hp, the screened MAF is certainly not an issue.

The C6Z MAF is also larger than ours. And there are plenty of C5 Z06's riding around with a CAI, no screen, and no codes. Based on the threads I've read, the biggest problem seems to be with the Vararam. It kinda makes sense now that I think about it, since the Vararam has two different air inlets that meet and potentially create turbulence. Most CAI's don't have this issue.

Guys my 2001 DOES have the stock screen still in place and yet the codes. Hoping that the tightening of the clamps will resolve my issues. Can't get the car out to test it because of the tornado/flooding rains we are having here.

I hadn't heard of it. Who is putting it on? I will have to check with the wife. Is there a website? My name is Shannon.

It's at David Stanley Chevrolet in Norman the NCCO (non-club club of Oklahoma). They've got a discussion in the Southwest regional section going too.
I used to hang out with these guys a lot when I lived in South OKC, it's a good crew and they usually get a lot of 'vettes to come out for the show.
