The stock filter is the best filter you can buy for filtration performance and is designed to flow more air than the engine can breath. At something like $45 for the stock filter that is good for 37,500 miles under normal conditions there is no possible reason for using an aftermarket filter. Oh I forgot, there are advertising claims of increased horsepower that is a farce.
Why would you say it's a farce? Have you installed/tried using the Attack Blue filter? I put one in about 1500 miles ago and I gotta say, my car is noticeably peppier. Unless you've tried it, not sure why you are disparaging the product. And btw, I have no connection to the seller/provider. Just a guy that used K&N's in my C5 and C6 Z06's, and now have a 2017 GS.
I just looked around the internet to see what the "Attack Blue" is supposed to do.
30 HP gain: Really?
Increased noise level "4.2 db's louder & deeper": Probably true and why you think your car is "peppier".
So what you are doing is trading "sound" for "filtration". Try to find some numbers about the filters effectiveness of capturing small particles on any sellers site or their site as compared to the stock filter. There are none. If it's better or even equal in performance why don't they show that. Because it isn't.

Actually, the manufacturer does show tests indicating an increase in HP. Can those be faked? I suppose so. But I can tell first-hand the increase is real. 30 HP? Out of 465 total that translates to ~5-6%, and I can see that...but even if it were only 15%, it's still worth it. Sound? Yes, a bit more throaty...but I'm telling you, my car is faster, sound or not.
You must have a very finely tuned rear end and I'm not talking about the car.
Just as an aside, if I were in the market for a used Vette and I saw that it had one of these "performance high flow filters" I'd avoid it like the plague. And I'd suggest others do the same.

I didn’t notice any power increase or improved throttle response when I installed the Green Brand filter. I did notice that the idle became higher and rougher for a few ignition cycles and miles until it relearned for the increased air. It probably did gain a few HP’s, I’m pretty sure it didn’t lose any.
So what the benefit of the Attack Blue filter? How much does it cost?
I paid $130 for my Stingray. Never noticed any difference in sound and power. The benefit is that it is easily cleaned up and reused. So it can pay for itself. I'll take it out of the Stingray and install it in my Z06 when it arrives. Some say it makes your exhaust sound a little more aggressive and adds a couple of horsepower. But just the reusable factor is good enough for me.

So "reuseable" is what matters most because of cost. The stock filter can be bought from Amazon for $61 and it's good for 37,500 miles. Two would be good for 75,000 miles and that's still cheaper. I'd suggest that 99% of owners will never see 75,000 miles. And there is no real debate on which filter is best for filtering out fine dust. Doesn't make sense to me.

Let's keep personal comments out of this, esp. mention of my rear end!
Several higher flow filters are used in many of our Corvettes. K&N air filters have been used for years, and, yes, the ease of cleaning is one of the big benefits. I would never leave an air filter in for 37,000 miles. The sucker gets dirty, and I've always felt more response when cleaning my K&N filters--or putting in new stock filters. Not sure what your beef is, but I believe that particles are getting filtered out of the Attack Blue filter just as well if not better than stock.
You may believe that but beliefs are not facts. And the facts point in a different direction. And just an aside, it's a fact that as a filter gets dirtier up to a point they get more efficient in removing the smallest particles.

No way would I void a warranty for a lousy air filter. 30hp aint happening either or GM would have done it
No difference between this paper filter and a K/N. Feeds well over 500hp just fine
After 26 yrs know this car well..if I cant feel it SOTP its not worth spending a nickel on. I bought that soup yrs ago also.

I understand that. Believe me. But I put a lot of miles on mine. I have a 121,000 on my Stingray. Ouch! It pays off for me. You can also shop rockauto.com and get the stock OEM Delco filter for $45.

And the less air that flows, by the same token. Don't you notice faster acceleration with a new air filter?
Interesting how GM made a performance intake with a different filter design that makes more hp? If the stock setup was the best at what it does, why did GM design a performance version?
I can posit this as well, why does an aftermarket air filter and/or air housing show a boost increase for the Z06? Simple, the stock housing was choking the airflow. If the stock was sufficient, then there would be no change to boost pressure as the flow would satisfy the demand of the supercharged LT4.
Observations in real life situations tend to indicate the "facts" that stock is best are indeed not factual.
Not sure about the blue filter but I just installed a BMS filter and it def had to have added some power. No dyno numbers but I dont need them. Car is def more responsive, throttle response improved, and the car sounds better.

If most owners will never see 75000 miles then it makes no difference if it doesn’t filter quite as well as oem.
