If you get any tune, the warranty is voided plain and simple. Unless you find an awesome dealer who'll overlook things and GM as well when the info is sent to them.

Nobody has any data yet on the Vengeance CAI with the green hipo filter. I've seen another post here with a drop in replacement green filter but no data on that either. Vengeance's CAI will undoubtedly make more power than the stock airbox with drop in filter, no question about it. I don't even need data to come to that conclusion when you see the construction of the inside of our airbox it is very evident.

I do like the Vengeance CAI price point compared to others. It's ridiculous however how much these things cost nowadays from every vendor though. Just a few years ago CAI's were half or less than they are now.
That's why I hope more options become available so they have to be competitive with one another.

Sorry that I was unclear...I have gotten a tune in the past with only a K&N filter and was pleased with the increase.

So Green Monster - no increased horsepower shown yet, requires tune and expensive

Roto Fab - expensive as Green Monster and no tune and shown horsepower increase

So if Roto Fab has increased horsepower and no tune, why would I get the Green Monster when it requires a tune and maybe void warranty.

So my point was, if I have to get a tune and void warranty and expensive CAI, I can do that with tune and K&N which I have done before and cheaper and pleased with the increase.

Is my point still clear as mud? I really need to take typing lessons... lol

I'm interested in what people think about dyno graphs showing an average loss of tq in the typical usable band just for a little peak hp on some of these CAI.

Everything makes sense now. I assume by green monster you are referring to the Vengeance CAI as well.

It's a give and take situation. With other mods you would overcome the loss of torque and exceed the original powerband everywhere if the package was put together properly. Cam has a lot to do with it. Too much excess intake air and you'll have it reverberating back up into the intake causing turbulence and loss of torque through the lower powerband. Too little and it'll be starving and still low on torque. Needs to be a well thought out package to really perform.

Roto Fab just looks better for one thing. I think GM will come out with a CAI for the ZL1 and a tune for about 40hp. This is my speculation only.

GM has always been good for aftermarket parts for peeps wanting to keep it all GM.

This is what I am hoping for that they offer now for the SS and offer for the ZL1 and a tune; however, this is only legal in 37 states.

Until proven otherwise, I think the Roto-Fab as a single mod doesn't offer much bang for the buck. Looking at the dyno graph how much of the HP gain is due to an increase in air flow and how much is the result of the AFR leaning out? At least the LSA version of their CAI showed increased HP and torque across the entire power band.

I have no doubt that in conjunction with other mods and a tune, the Roto-Fab will likely show some significant gains. But as a single no tune mod, I just don't see it as being worth the money. And the loss of low end torque is a real concern.

For me, the noise alone is worth it. Any increase in power with a CAI is going to be fairly minimal on any platform.

There is enough room in the stock tune to adjust for most bolt-on mods. So although the tune is technically leaning out a bit, it definitely isn't running lean at all or even close to lean. You gain a small amount with a cai. Whether it is worth the price is up to the individual buyer. But nobody does a single mod and calls it quits. People do several mods. And once you start adding more mods, the cai will start to show it's stuff. Ask any one of us who bought the RF or any other cai and we'll tell you it was worth the price.

Trust me, I know all about cold air intakes. I had a Roto-Fab CAI and their Big Gulp brake duct replacement on my 2013 ZL1, and a Cold Air Inductions intake on my 2012 2SS.

As a single, no tune mode, I don't think they're worth the money. Now if you're talking about coupling them with a custom tune where the AFR and timing are adjusted for the intake, then we're talking a different story.
