What do you think a K&N Air Filter would do for L99?

So is it worth it to put a K&N air filter on the 2SS with Auto? Would I really gain anything or would it do more harm than good?

k&n filters are excellent

k&n filters give a little more horse power and a little better gas milage on pretty much every car . i would say it cant hurt . i have put them on all my cadillac escalades .and seen a differrance . my latest car i put a filter in was a 400hp 6.2l escalade and i do see a differance . it will proberly take some time for kn to make a filter for this car anyway. some times they my not just make the filter they will come out with a whole air filter system for a certain car

Nada Zippo Nothing. A fellow Corvette buddy sold his LS2 vette for a Z06 and gave me two brand new K&N filters. So I dropped them in, with a week the car was running poorly and I had CEL. Took it to the dealer and they claimed they were "over oiled" and caused contamination of the MAFS.

They covered it under warranty but told me to remove them.

And just ask this question over on the Corvette Forum and you'll be told not to waste your $$$. There have been no proven HP/TQ gains reported on the LS2/LS3 by just changing air filters.

Please ask this question and see what thousands of Corvette owners have to say. Don't take my word on it.

I have to agree with Tom. Absolutely nothing. Had it on my 96 Ram Air T/A and the only thing that this filter is good for is well, maybe not having a cheap paper one but besides that, it doesn't do anything.

Its not so much about the filter, but rather where its located in the engine bay. If it is only sucking in hot air you'll see poorer performance, but if it is in a location where cold air can get to it you'll increase the performance. Cold air = good.

It most definitely does something. It may not be in the form of power gains but it will filter far smaller particles than a crappy paper filter and it never wears out. It flows more soaking wet than a paper filter will brand new. As for the oil, that was the fault of the person who oiled it, not the filters.

You guys are all correct. I have had buddies that have over oiled the K&N filters and had terrible problems. The key is to NOT over flow the filter with oil!!! On the other hand if you do the complete K&N FIPK system you will be able to feel the power by the seat of your pants. On my 2006 Silverado SS I installed the FIPK system and could feel the power as soon as I installed it. The FIPK system is also much more agressive sound wise. The new Camaro has a sound branch comming off the factory air box so I will bet that when K&N does a system for the new Camaro that will not be there and the FIPK will be louders and give you more H.P.

The filters were brand new still sealed in the factory plastic bags. They do nothing. Believe what you will but Corvette owners for years will say the same thing.

As I said don't take my word, get an account on the Corvette Forum and ask the same question. Then report back with the results.

What about the air intake kit that is being offered as a dealer installed option on the Camaro? Thoughts on it?

I have no idea what they do on cars, but I used them forever on my bikes and gained on average about 2-4hp depending on the bike. Dyno tested.

However, that really says nothing about what they would do on a Camaro...or Vette. Each car is different.

i looked at many filters for my GMC & went with AirAid because not only did it offer more power (dyno shown) but it was almost half the price. it definitely made a big difference. this is an open cone filter thought as opposed to a stock replacement filter.

Dont' over oil it. In fact barely put any on at all. DO NOT OIL THE INSIDE OF THE FILTER.

In a mostly stock motor you will feel the difference in throttle response.

In a modded motor it is a nice complement to exhaust mods. When combined you cant see noticeable power gains. I would recommend a shrouded setup that blocks out the hot air from the engine compartment.

I'd be VERY careful with any oil-impregnated air filters. They have been known to allow their oil to get sucked off and into the Mass Ari Flow Sensor and one of the results of that is it giving off funky readings, and burning up transmissions. This is not a myth, but a fact. I would stick to the dry high-flow filters or even kits. That filter looks like it's going to be big enough not to impair flow much, if anything - I'd look in to cold air systems when they are available (and GM will offer them) and look to eliminate any resonators or baffles. FWIW, if you have any familiarity with 4th Gens., a lid, but itselt, would net about 10 RWHP because it eliminated the ribs under the lid and the baffles that were at the outlet. Anything to smooth flow and transition smoothly is going to be a benefit and if you can keep it in cold air, it'll give even more power. It is fact that air temperature can effect how the PCM runs the timing and fueling and such, so the colder air the better.

Again, I'd recommend looking into the GMPP cold air system when there is more information. I can guarantee that they will test them to make sure there are no oiling problems and place them in such a way water intake will not be a factor, another thing to consider.

Nothing wrong with going with K&N filters .. have never had an issue with them .. just don't over oil them ....

I'll be more interested in a FIPK from K&N and not just the filter .. I will not do anything that goes into the fenderwell though .. to much of a PITA to clean and the chance of sucking water into it ...

Very rarely do oiled filters cause a problem for the MAF or the engine. You will get codes until you have a tuner in your possession. Otherwise, you'll probably be fine from a technical viewpoint. The odds of something messing up are very low.

There are other points to consider, though. Intakes, while they give you a couple of bonus ponies in naturally aspirated engines, do require separate maintenance. To get all of your horses, you need to keep them very clean. If you go to the track and dyno right after installing it, you'll see benefit. Wait a few hundred miles; dyno again. You'll see what I mean. They get dirty if you're not maintaining them, and then they turn into shiny but useless performance parts. This problem will vary extensively based on where you live.

Maintenance is a problem for another reason, as well. When you take your car to a dealer with obvious performance parts, some tool at the dealership will always try to writhe your warranty away from you. You need to know your rights as a consumer. Do your research. In this case, it is really hard to prove that the oiled filter caused a problem in your engine, but MAFs aren't priced like Happy Meal toys. If your MAF goes out, the dealer will always pin it on your intake, and you are going to have to pay for a new one.

Additionally, you've got the issue of forced induction. If you plan on supercharging your motor, it is very possible that any intake may not work for you. You'll spend a ton of money on a performance part that you'll end up selling later. You could argue that is is fun for now, but both might cause your warranty to be worthless, at least according to your dealer, so you might as well put that money toward a turbo or super for your car if that's in your future plans.
