You know the motor isn't sucking 100's of square inches of air per second like a cruise ship or something. The car doesn't need large tubes because it looks cool. A dry performance filter is what I replaced all my KN's with. I got snappy response with less dead spots though out the power band.
I do throw a code from time to time but the ECU adjusts eventually
Is there a seat of the pants difference that you feel between OEM filter and the green?
First time to strip and never ran car with OEM paper filter. "seat of the pants" means nothing without data...ie trap speed or dyno. Car is running great at strip without any hesitation.
Everything I've seen leads me to believe that the stock filter, not the stock pipe and airbox, are the bigger restriction. So I plan to run the green aftermarket filter and the stock box, see how that does.
My guess is it'll give me 75% of the benefits of a full CAI without the surgery.
I was one of the first buyers of their CAI. It had a number of fitment issues. I was told I was doing it wrong. They later said they messed up first batch and it was all good now. I bought the newer one. Much much better fit but still way too close to radiator hoses no matter what I did. I was told I'm doing it wrong. Now I heard they are redesigning the box to fit better. Do I dare purchase a 3rd one from them??? They should offer to change out the box I currently have for free. We'll see what happens.
It sure does make serious power though. Transforms the car and makes it more fun to drive. That said, it's sitting on my shelf and I'll probably sell it like I did the last. Maybe I'll go filter till I hit 100k miles and then game on.
My only worry with filter only is that people seem to say it's better at first but gets clogged more and faster than the stock filter so over time its worse than stock. ...but people say a lot of ****.
Best,
Gene

I'm looking forward to your impressions as I'll probably go this way if convinced.
I would agree with your statement here... fitment is not great buy manageable...
My car picked up .22 sec in the qtr mile ET, and 5.3 MPH trap speed (after I added the Halltech CAI).
I would not get it if I have a 2017 though, too many people having problems with the stock tune being too lean with the HT CAI. This CAI leaned my car up one full point, but my car is a 2016 so it's ok.
Today, with my stock car/stock tune (2016 C7Z06 A8).....
(with halltech CAI and TRIC, and Drag wheels/tires)....
***NO OTHER MODS***... ran a 10.39, 10.40, (2) 10.41's and a 10.42
(the fastest time today was in +255DA).
I am a believer, and so are the countless modded C6Z's, Hellcats, and GT500's and others who have seen it in action, from the rear.
What was your best speed with the TRIC and Stinger-RZ?
The 2017 code issue happened to one customer. It is a MAP sensor issue that we have not seen before or since. We have a 2017 in our shop and will provide more on this soon. I know of a dozen or so folks that have 2017s without any codes or issues.

As I mentioned, the bulk of the issues with fitment come from the much larger airbox we needed to fit our high flow filter. The larger filter, provides much more surface area, and does it without ruining your bores like some filters out there.
If there is insufficient clearance between the airbox and lower radiator hose, there is a good chance you will have fitment issues.
I have a video showing how to do it right coming today.
The air fuel ratio has not change since the 2015 Z06. We still see Lambda .87 - .88 in open loop on the dyno, track or road. This is a safe amount of fuel enrichment. Once the COT parameter kicks in around 4000 rpm, fuel enrichment takes a leap into the fuel enrichment dark side with .75-.78 Lambda. Here is the original dyno done two years ago by Smokey's Dyno:
Please note that Smokey's show Lambda 1.00 at 14.77:1, which is incorrect for e10 fuel.
We have well over 1200 systems sold and installed since 2015, including the biggest names in the Corvette World. GM tested our intake during our carbon fiber prototyping, along with Katech, Texas Speed, Livernois, LG Motorsports, Speed Inc, Tony's Corvette, Vengeance Racing, Hinson Motorsport, and many GM dealers as well.
Actual air fuel ratio using e10 fuel was between 12.4 to 12.6:1 (Conversion factor= .959)

I had (and continued to have) issues after the install where the added benefit seems to evaporate after the car is up to temp and actually seems more sluggish than with the stock airbox. I too was told it was my install error after I had fitment issues - the fit is marginal, particularly how the box is sealed against the post-filter intake tube and how the box seals against the bulkhead.
I think the theory behind the Halltech (biggest filter, velocity stack) is superior but the design, execution, and installation documentation of the AFE is better.
My input re: how to make the Halltech better would be as follows:
1. Design a spacer into the box and stack to ensure the radiator hose does not directly contact the intake wall
2. Redesign the airbox with a flange to seal against the bulkhead that also permits attachment of the TRIC on the other side of the bulkhead.
3. Design a better seal between the box and velocity stack.
4. Create more comprehensive instructions that are done before product release - these should be on a PDF or in a single online video.

Impressive Dyno data for sure, but this was done on a 2015 car. There are many issues with 2017's Z06 throwing a P106 code. I think you ought to do some testing just to confirm the data is still valid for your CAI on the 2017 Z06.

1) Good idea, but the video will show how to move the hose far away from the airbox.
2) We provide a 44" seal with each kit that seals the F-panel where it is attached to the airbox entrance.
3) This is one of our goals. The 3M tape we use is heat activated, and we have no problem getting it to seat and seal with our giant flamer. The customer does not have ready access to this type of heat, unless a hair dryer is used. It will stick when applied correctly, but only once, then it is ruined. The only way to resurrect it is to use Weatherstripping sealant once it has been removed.
4) We have had the video instructions available since day one, and a pdf file shortly after that. We might have to revisit this to make things clearer, or more comprehensive.
By the way. Halltech has been a forum sponsor for almost 18 years, and has purchased 12 Corvettes in that time to get this right for the forum. We obviously need improvement here, which I think you will see with the video of the airbox clearance. By comparison, our competition borrows a car for their intake, then returns it to the owner. Why would the forum decide to purchase intakes from a non-supporting vendor that could care less about sales here. The forum represents 99% of our sales.
One P0106 code and it ends sales? Really? The fellow that posted that issue was one of our first customers, back in 1999. We spoke by phone and email about his code at length, and my advice was to start by replacing the sensor. He replaced the MAF sensor instead. That code is related to the Manifold Absolute Pressure. https://www.yourmechanic.com/article...by-john-nelson Have I missed the other members that have posted this code with our intake?
We spent $102,000 on our Z07 (granted we went overboard, but that was the only one available at the time). We have been long term testing now for 2 years and 8600 miles, trouble free.
We have a 17 Z06 in our shop that we are installing the TRIC and Stinger-RZ package, and will get an improved video and pdf instruction manual. Then we the snow stops here in WI, we'll get some road testing.
