So your comment was basically just false and then you used data from another air filter that did not even apply to the op's question. And guesses are like opinions. No data, no one cares. But at least you came back on and admitted you did not have the correct info.

 

The attack blue and other dry filters are nothing like a K&N filter. I still have a spare K&N from my LS3, and side by side with the GM performance filter and Attack Blue filter, the media used is far finer than the K&N. The K&N relies heavily on the filter oil to do filtration, which does work when oiled correctly, but when not done right, it is quite porous and will allow larger particles through.

 

The Attack Blue was tested to SAE and ASHRAE standards and performed better than OEM. If you took the time to look you would see the results for yourself. Your guess is not very educated.

 

about Attack Blue from their own:

• Nanofiber technology captures dirt down to sub-micron levels

Bad guessing walt white coupe.

 

You guys sound like you actually drive your corvettes and plan to put 300K miles on it

Enjoy the small HP and Sound bump my bothers and dont worry about the rest.

 

I could care less about the filter, not op....I just don't like false data being spread as if it was true.

 

This is promising; better filtration than OEM, coupled with more power is a great combination.

Do you have a source for the testing results?

 

Google it

 

Like Elk said: Do you have a source for the testing results?

 

If you don't believe what I posted then Google "Attack Blue Air Filter C7". Then read and educate yourself. I'm not doing your research for you. At this point I'm really not interested in your opinion. I find you posts insulting.

 

walt white coupe comes on here and lies about an air filter, we call him out on data because of his claim, after awhile he finally admits he made it up. And now he is trying to ride someone else and call you out for something they can google since it is actual data.

 

I've been running the AB for about a year. I purchased my C7 used and it had a oiled K&N which I'm not fond of so I did a little research and decided to try the AB and it seems be be as good if not better then the K&N. My C7 has run faster with that filter then the 2 Cold Air Intakes I tried and was not impressed with either and sent them back to Summit. One of them actually slowed my car down and the other fit so bad I never even started the engine. I won't mention the brands but not interested in cheap versions that didn't fit properly or perform as advertised. Still running the Attack Blue

 

I will stay with OEM, regardless of all their claims.

 

 

A used oil analysis would reveal how much fine particles are passing such as silicon. It's not a true measure of air filter efficiency or filtration capability as you could just not drive the car have a clean reading and claim that it did well just as running no filter can elevate readings.

The point of it is that in comparing the media of paper oem and the attack blue, the attack blue density and similar dry filters is quite exceptional and unlike the k & n also run microfibre density that can exceed paper's filtration level and be more breathable.

I did the google search and no real testing data shows up other than advertising claims. What is so hard about posting the link, IF THERE IS ONE?

I'm sure others would like to see it also.

 

You are trying to validate your claim that it does not filter as well as stock by saying there does not exist any testing data in the searchable internet.

You cannot equate lack of a search result to validate your statement that you are right, just as well as you cannot also find the same data which says it does allow more dirt in.

So far all we have to go on for truth is; there exists a subset of users of attack blue users since the C5 generation that have not had issues with the attack blue and similar designs. There are users with used oil analysis results which do not support the idea that more dirt is getting in the engine with their dry filters (attack blue and others) There may exist users who have had more dirt in their engines due to filters, yet I have yet to find someone who had a used oil analysis that can back up the fact that with the attack blue or other dry filters that there was a substantial increase of dirt in the oil. We also have many videos indicating that dry filters and anything that increases the filter media size will show an increase in HP over the stock filter on the C7 platform.

That is about all we can infer from what is available. You can choose to be of the opinion that it lets in more dirt and just not buy it. Others who are touting it are just as valid to say it works as you are valid to say it doesn't work, but the data leads credence that it is more positive than negative after comparing opinions.

 

I drive my car about 2K a year and change the oil yearly so I could care less about an increase in dirt, but I do care about an increase in power. If that is the case with the Attack Blue air filter, I would consider getting it.

 

If it's so good, why didn't GM put a performance filter in there in the first place? Just curious...
.
I"ve always found that performance filters by themselves on a naturally aspirated engine are just a waste of money. I'd like to see the before and after dyno results including temperatures and conditions (before and after) which can affect the dyno numbers in "favor" of an increase.

 

GM did release a performance dry filter. I have both the attack blue AND GM performance dry filter. Both show an increase in HP over stock and are very very similar in design, just I prefer the blue mesh media versus the red mesh.

As far as back to back dyno results, those are readily available videos and posts and dyno sheets which can be found.


Both the power curve and torque curve show increases over 4k rpm, the initial stock 3 runs are fairly consistent then the attack blue shows that in the upper rpm, there is a gain. The final peak numbers aren't all that different, but its the area under the curve which will show gains. The key point is that when you increase the area under the curve, it will show up as better acceleration. In the case of 2 identical C7 LT1 cars where only the filter is the difference, the attack blue filter car will pull ahead of the stock filter by probably 1-2 car lengths at the end of a 1/4 mile.
