Cold air induction on a C7 Stingray myth?

You should put a pipe and filter on yours and see how it runs. Believe it or not there is engineering in it and it is not like cars of long past with separate MAF's on them where you could just put a pipe on it. The cost be making the Green setup with all the work behind it will be a very long time before all of that is paid for. You get what you pay for, so I would be careful if you are shopping by price.

I forgot the most important question, CARB legal. Actually the box's that require no tuning should fit the bill for being legal if they were tested. However it takes more than just making a part that works with the emissions to become legal in the CA, it's called CASH and lots of it. So if you spent say 25k in developing a box, you have to sell, you may have to sell a couple hundred to pay off the development, but if you CARB it, you will likely have to sell a thousand if not more. How many CAI's do you think someone can sell. It really easy to say, not making it CARB compliant so that a handful of customer in 1 state can purchase it. Here in lies the problem.

Go to any car forum and the CAI guys fight "the good fight".
From personal experience just installing a CAI does diddly on todays modern sports cars. Factory intakes are already designed for optimum efficiency.
Any dyno with a CAI showing gains is one of two cases:
A. Normal standard deviation from dyno runs due to environmental and other uncontrollable conditions.
B. The car has been tuned which is where the actual gains are coming from.
My last sports car had just a CAI on it. It made no discernible difference.

Just bought an AFE for my Z06. Dyno shows 46hp with stock 650hp or 7%. Im expecting a noticeable difference when I install it. Other people have said they have noticed a difference. Not sure on a non SC C7.
I think buying an air filter by itself if your current OEM air filter is fine is a waste. Not enough power increase to notice a difference. I'm guessing you need about 5% power increase to notice a difference.

Cheapest is not always the best VALUE. There's a difference!

For the non supercharged C7, you only get 12hp increase with CAI. Thats not enough to notice a difference and therefore is not worth the money.

On hp but not on value!
Depends what are looking for! When NPP was an option in 2014 I paid $1100 for 5 hp and “noise.”
I paid <$500 for my low restriction larger oiled cotton air filter, larger filter housing and reduced restriction inlet air duct.
I got ~12hp and "noise!" Get about the same "noise" level as NPP when both at WOT! 4 times the hp value, about the same noise!
Could argue NPP is not worth it either!

Nice to have goals!
I found a post some time ago interesting. They tested and got less hp when they removed the air filter! Not sure how accurate but the MAF is close to the end of the filter and turbulent flow passing over it could cause inaccurate and inconstant flow reading info going into the computer!

I'm in possession of the latest VARARAM! C7 test unit. I'm always impressed with the products that Patrick @ Vararam puts together.
Hey holds them back and plays with them till their perfect.
Hopefully over the holidays I'll have time to do a before and after comparison.
Keep watch!
