Has anyone INDEPENDENTLY tested a cold air kit & noticed a power gain? I've heard from several shops saying they didn't see anything from some of the stuff out on the market.

Good luck around here finding a independent test that actually looks at the right things.

Any gain from an intake (on paper) would not be enough to feel... Might sound better but you'd never be able to tell by the seat of your pants... My point is, it's kind of irrelevant if he intake ACTUALLY adds any power or not.

Agreed. When you are already working with 455hp it is heard to feel like 10 more hp, usually at high rpm. Intake and exhaust may yield you 20-30hp at peak but you will need time slips at a track to see the results. If you want to feel a power increase then add a supercharger that will add 150 lb ft of torque low in the rpm range.

Not to my wallet, it's not irrelevant. All this means is gm made a good factory intake that's not worth changing. So either no one has done a good job yet at improving it, or its not worth improving

This is how I feel as well. How many hours of r&d and testing go into the intake system? Do you think anywhere near that number of hours go into the aftermarket products? I'm also not convinced in the end with a full tune your gains are significant enough to outweigh your losses in efficiency.

I will be purchasing the Rotofab unit and doing a proper apples to apples comparison. This will not be a mere before/after dyno test as that tells you really nothing. I will be recalibration the MAF transfer function with the Rotofab installed and then focus on the dyno results. Unless the MAF is recalibrate you can't figure out if the gains are due to tune influences or actually mass airflow increases.

Awesome! We appreciate your time and effort on this

Adding a CAI on a stock car is a waste of money imo. When you start adding headers, exhaust, boost etc.. Thats when you need an intake

a lot cannot afford to do it all at once, so it could be a first purchase on the road to getting all those items.

What are you going on about? Lol...

Like an intake is going to make more power after you do headers and exhaust than if you did it before or something.

Your opinion makes little sense. Ya know what though...I think headers and exhaust are a waste of $$ unless you have a CAI.

CAI = more airflow at lower temp = improved performance. bottom line.

Does this quality as an independent test?

Then add Hooker Blackheart axle back exhaust, and....
"Back on the dyno, the results were impressive. Max gains were 15.2 wheel horsepower and 21.5 lb-ft of rear wheel torque, but equally impressive was how the Camaro picked up power across the entire powerband." - SuperChevy

CAI does not guarantee any of that. Assuming there are legitimate pressure drops and/or thermal issues with the factory intake there can be improvements made. However just because some vendor creates a CAI does not mean it was properly engineered to remove the factory pressure drops and not induce its own. Nor does it guarantee better thermals nor does it guarantee your tuning won't be skewed due to MAF issues. Not one person on this forum has shown a quantitative representation of pressure drops in the factory intake. And certainly not one vendor has show they have eliminated any such pressure drops.

Stop putting so much faith into the vendors. You have Mishimoto creating parts for parts that have ZERO history of being deficient or a problem. People will buy anything out out there because it's new or different.

That link above is a bunch of crap.

afe power is working on one of the best intakes out there as we speak! should be on my car shortly
