Cold air intake
i think I saw something in the forum on adding "cold air intakes" to the C7. Do they make that much of a difference? And is there a difference in the aftermarket brands, K&N, Haller, etc?

AFE has been very popular, and probably the best bang for the buck. Throttle response is crisper, and you will love the throaty intake sound. I think there are a couple available right now in the parts for sale section:

found aFe on line, I like the window idea to let you know the condition of the filter, K&N is completely open and the Halltech is totally enclosed. just what I have found so far. with concerns of "computer" sensitivity on any add-ons I am hoping for any further investigation into these things.

I installed aFe to my 2014 after I added Corsa Exhaust. I had it dyno tuned because of more air in and out and was pleasantly surprised to get an additional 47 rwhp.

From what I have read, be careful with oil coated filter elements (like K&N), too much oil on them can mess up the MAF sensor, and not enough will let dirt through. I would stick with dry paper elements, for whichever system I would choose.

I looked at going with an aFe cai but after looking at the published flow reports and talking to local tuner I decided just to go with a K&N filter replacement.
According to aFe and K&N's websites the aFe cai has a flow of 318 cfm @ 1.5 H20 for approx. 500.00. K&N on the other hand published that their filter flows 312 cfm @ 1.5 H20 and only cost 65.00.
I have also read numerous post on here that say the factory air box flows well.
Personally I don't see 6 cfm of airflow being that much of a difference.

I have a Halltech CAI, Ktech TB & Faster Proms (Formato) intake manifold, but an otherwise stock Z51 A8. I turned an 11.8 when temp was almost 80 and the DA was between 1300-1500 at Bradenton (30 ft ALT - VERY humid). I get a little throttle stutter from Ktech TB (based on other posts) when the car is cold, but once at driving temps, it runs flawlessly.

from what I have seen its nothing like the c6 cold air. since the air comes in exactly where it does stock I see no difference there. Better filter alone will gain some cfm's and maybe the tube add's a little but really its not doing much.
Now on the c6 it did both ram air and cold air so there was a bigger gain. I haven't seen and neither has my tuner who does only vetts seen any cold air that is adding much of anything except like I said a better flowing "filter"
but it's your car so do what you like. its a forum so guys just have to believe what they want and leave the rest.

I installed the aFe airbox on my 2015 Z-51. Very well made system. Easy to see the filter and determine when it is time to clean it. The sound is a little deeper. I like to track the car once a month. My lap times have been coming down every session. Hard to say if its experience, fresh tires, cooler temps, better drivers on the track or the aFe system.
Bottom line - aFe made my experience more enjoyable.

Try searching the Z06 threads, I would guess over 50 different forum members with about 20 differect shops showing dyno gains from around 30hp to 45+hp no tune just CAI swap. I have installed both the Halltech and now AFE. I can for sure feel the difference. The problem for us Z06 guys is the filter is same size as the Stingray so it is a restriction. I can not say the same for the Stingray? I am very pleased with the HP/TQ gains.
