Difference between AFE and HALLTECH CAI
Whats the difference between the 2. I mean why choose one over the other? Does one have more hp gains than the other, or is one easier to install than the other? TIA.

Answer to difference......
$1,000.00 difference in price between the two seems to be the difference I can see from reports posted herein. If there is only 2-4 HP difference between the two, and the difference is almost $1.000.00 more.....is that small amount of HP really worth that sum of money?

They are actually the same price; the CF version of the Halltech was just released and accounts for that price.
Just bought the Afe from Norcal. $500 is a HUGE discount you may not see that often.
Afe is very user friendly to install, or remove, where there is no modifying involved whatsoever from what I have seen. I would hate to get the Ha;;tech, have a warranty issue and not be able to set things as they were to avoid any headaches that might occur.

To install you just shorten/cut several inches off one small rubber fuel line and lengthen another with a line provided with the Halltech kit.
To go back to stock you can leave the longer line as installed with the Halltech and buy a longer rubber line for under $5 at your local auto parts store to replace the one you cut. I'd have to look at mine but I think you can go back to OEM just using the line you cut.
It really is simple.

Nope...not like me to be ignorant before making a decision. I watched just about every install video available before my decision. I also paid VERY close attention to where Halltech does not recommend anyone but a professional install because of the 'modifications that are necessary. I also looked at what people thought of the installation procedures historically and.....when all that is said and done, I chose Afe and enlisted my opinion why when someone asked...
Halltech: We highly recommend professional installation. The airbox is sealed, but is much larger than stock to promote better airflow, but it requires moving some of the engine bay components, and some modification.

A friend of mine and I did the install of my Halltech on my C7 Z51. It took us about an hour-we went slow to insure we did it right.
We also watched a LOT of video's to insure we didn't mess up anything.
Everything turned out well.

When they first came out the AFE drastically leaned out the A/F ratio, the Halltech, not so much. With the first units, using the data on AFE's website, I would not put one on without tuning. But both showed similar gains.
Recently, Diablosport tested the AFE and it did not affect the A/F as much. Must have been a running change. I don't know if the change affected the final HP gains.

I have the new -1 Afe. Wish I would of got it from NORCAL and saved some money. But I did get the Corsa X from him. Point is, my car was the one that Diablo used to tune with the new AFE intake and the A/F was pretty much spot on with the stock tune. So whatever changes AFE made worked.

I only have 6800 miles on my Z and it was at the dealer for over 6 weeks for a phantom electrical issue they could not find until 6 weeks later. The General did right by me and made a monthly payment for me.
I have the mod bug again and want to research all options before I jump in!
My goal is 750-800 rwhp, but daily driving streetability and NOT breaking motors, trannies, parts and stuff are my main concern. Factory warranty will be out the door so keeping the boost and tune conservative will be key.
Anyways, let me know what you have done and if you have any dyno #'s.
Thanks,

Shark, what other mods did you perform? How do you like the Diablo tune?

I had 1100 miles on it with about 200 having the AFE installed. Only other mod is the Fasterproms Expansion tank. Car feels really good. The car was not lean with the AFE intake so not much picked up peak HP and TQ wise. But the throttle response is great and it drives really nice. Tried to go to the track last Wednesday but it got rained out. Here are the results and dyno chart on the last page.

Diablo dyno'ed Sharkgray's Z to be about 40 hp above stock with the AFE installed which is pretty close to AFE's claim. Not sure if Sharkgray had the lower restriction oiled filter. If not that could account for the 6 hp difference. Regardless 6hp is within normal variance for these test.
To clarify Sharkgray's comments in his last post. Diablo didn't find much additional power by tuning for the AFE vs the stock tune and the AFE. They did gain some mid range tq but practically nothing for hp.
Diablo verified they did in fact try to lean out the afr further than the AFE does on its own but didn't gain much by doing so.
This confirmed the AFE system was pretty much at the limit of what one can expect from a CAI.

AFE currently claims about 46 hp for their intake with their highest flow filter. Not sure what they claimed before the -1 modification was released.
