I am currently using the AC Delco A3107C / 25940997 air filter because it is the most free flowing of the GM filters, also kinda expensive.
I am asking if there is an aftermarket air filter that flows as freely that is cheaper.

I see a couple of filters out there the ACDelco A3077C, WIX 49997, FRAM CA10782, GM 15776148, has anyone used these and are they comparable?

I have the filter you have used for sale, it only has 24K miles. I'll give you a good price shipped to you if you want it.

The one I recently installed is fine, I'm actually looking for a new one to put on the shelf.

"Free flowing" in otherwise equal surface area filters normally means they just let more dirt pass. The least dirt a filter ever lets past is when they are the dirtiest and most restrictive.

I use Fram engine air filters in the C6. Fram makes horrible oil filters but their air filters are pretty good. I would also trust WIX. Supposedly the WIX has more surface area which would result in more flow but it may also use a different material which could restrict flow and improver filtering.

I never found that ones on the shelf work very well, especially when the airflow direction side is placed face down.

I just put a large towel in place of the filter, that way, when it gets dirty, I just throw it in the washer. It flows pretty freely too. I bought it at Target. I also picked up an extra 8 hp.

Looks like the answer to my question is no.

It is just hard to beat the OEM but easy to screw up MAF readings. Besides it is only replaced every 30-40k miles so the extra $$ is not much in the long run.

I drilled holes in mine -- 1/2" dia.. seems to be free flowing. Plus about 9 more HP.

You are 100% correct. I just start looking for another when I take the last one off the shelf. I think I paid like $50 each for these last two. I was just wondering if any of the aftermarket was up to the ZR1 style filter yet.

I don't know why when ya ask a serious question it seems to draw in some stupid every time.

I am not buying into the idea that an air filter element that has the [capability] to flow more air is going to make anymore HP when used on an LS3, than a filter that flows just slightly less air ...

The reasoning is that the OEM air filter used in the LS3 is More Than Enough for the LS3 engine as is.

Case in point ... The 436 HP LS3 uses the same air filter element that the 505 HP LS7 uses.

If this filter can supply enough air for the LS7 at wide open throttle, it certainly can supply more than enough air for the LS3.

And that's why these aftermarket CAI stystems are pretty much a big waste of money ... other than the fact that some of the aftermarket CAI's may provide for a cooler air charge to the engine (which certainly can increase HP) .... but, again, I believe there is no actual airflow differences in any of these filters when used on the LS3.

Just my opinion folks

Summit sales the dry green Hi-Flow filters that work great.

Ya see the problem here is that I Am the Original Poster here and I am looking for information on Air Filters. I am NOT looking for your Opinion on weather they work or not. I have no interest in a he said she said thread. It's pretty F'n sad when a person cannot come to a forum and ask a question and get an answer without having to listen to someones Bull ****....... oh yea.....just my opinion.

please stick to the topic of just close this Thread.

I use the K&N it flows 50% more than the OEM filters but i also have headers and Borla stringers.And NO my MAF sensor does not get dirt or oil in it.If you look on how the K&N is made you will see 99.9 % of the dust is collected on the outer ribs..Good Luck on this filter subject...

Turbo6TA

You posted a bunch of part numbers of various filter elements and asked if any of them were comparable to the OEM filter. First off, none of these filter manufacturers state the actual flow rate of there particular filter ... and there is nobody here on the forum that can tell you if one is any better than the other.

As to my previous post ... believe it or not, I was actually trying to help you understand that the filter in the LS3 is the same as in the LS7, so it's more than capable in supplying the airflow requirements of your engine.

If you have some misguided thought that one filter is going to get you anymore HP than another filter, you are wrong.

Again, all I was attempting to do was to help you along in your search for a new filter, but you jumped all over me for posting what you did not want to hear.

Maybe you should worry less about air filters, and worry more about anger management and temper control.

Have a nice day

Since you don't seem interested in serious answers that happen to disagree with your preconceived ideas, please do.

Serious answer. Probably and maybe.

Since you've already checked and have seen ads for each of these, you probably noticed they all appear identical with the exception of the label. The prices range from $23 to $122.

At one time your local dealer offered 3 different filters. One for base, one for Z06, and one for ZR1. The primary difference being the density of the cores with the base being the most dense and the ZR1 the least.

Unless you can confirm which density each one has prior to a purchase, you'll be stuck with whatever they ship you. Since I'd guess only Donaldson knows which supplier is buying which density and what they supplied to GM, but I'd also guess they won't tell you.

As to what is comparable and which flows the best, you have to find a lab to do tests of all brands. Since you're concerned with price, I doubt you'd be the one to pony up the bucks for testing.

Now here's my opinion, like it or not. Your engine will not die due to poor filtration with any of the filters you mentioned.

actually..... not so...
Here is my question again in case anyone missed it.

I am asking if there is an aftermarket air filter that flows as freely that is cheaper.

I see a couple of filters out there the ACDelco A3077C, WIX 49997, FRAM CA10782, GM 15776148, has anyone used these and are they comparable?

OK see... you provided an answer to my question not a debate on weather or not the concept of what I am doing/want to do is Valid.
I am not a scientist (nor did I stay at a Holiday Inn) but there are people here on this Forum that have a Ton of Scientific knowledge.

I've used K&N om my 1998 Z28 almost since I bought it New in 1997 and have had no ill effects. I am looking for other peoples EXPERIENCE not so much opinions, seems to be harder and harder to get these daze. But Thanx for your reply anyway.
