K&N or no?
Sorry if this is already addressed on the forum. I ran searches for anything with "K&N" or "K & N" and turned up nothing.
Anyway...
I just bought my 07 C6 and wanted to know what the opinions were related to putting K&N air filters in her.
Your input is appreciated. Thanks in advance.

K&N Filters
My Father was a fuels and Lubricants scientist who worked for different oil companies and even a motor company. When I asked him about using a filter like K&N he told me that they can help performance as the engine can breath better, but small particulates can get pulled into the engine and that can cause faster wear. For many people they might not ever notice any problem, and many of us do not keep our car for 100K miles, I tend to 
My dad and I built many race cars together and even those going to the drag strip we would run an air filter. We looked for our horsepower elsewhere (Cam, Carb, headers, exhaust, and cubic inches

210,000+ on another car that I used to use the K & N filter cone that came a ram air kit and the Ram Air Kit helped..

Was wondering the same thing. I did a search as well and did not find much, I guess no one is really using them. I want to leave my car basically stock but I need to change my air filters and wondering if K&N is any better then the paper ones? I have read that the paper filters actually flow better then the K&N but I don't know if that is internet rumor.

A K&N will be a good choice. Next step is a CAI that picks up more cold air from outside.

I believe in those screen, gauze and oil type filters if you're looking for a simple, 'easy to swap out' set up but like Dennis said above it's not really worth it, just get a good cold air intake instead.

I know that K&Ns are supposed to allow better air flow over paper filters but at the same time filter down to as small or smaller particals of debri, etc. I'm not sure where the information is coming from that says they allow more stuff through them. I've never heard that before.
Not over-oiling them is key too, I know.
I guess I was just wondering if anyone had noticed an appreciable difference between paper and fiber versus the obvious of not having to change them out, etc.
Greater flow is an advantage of the oiled fiber filters like K&N. I guess I'm just looking to "upgrade" my intake but leave the car in stock form which a CAI will not allow me to do.

I'm sure there only make limited HP gains, but WTH.

I had a K&N aircharger intake on my 2006 C6 and I currently have K&N replacement filters in my 2005 C6 and my 2007 C6.
I don't really notice any acceleration difference in the cars, but I like knowing my filter is good for well over a year without being cleaned or replaced.
As for the 2006 with the K&N aircharger intake, it trapped a very high 115.85 with just the K&N and Corsa Sports, I kind of wish I would have kept the aircharger.

Just ordered a couple K&N panel filters. FWIW I removed the secondary cover and just left the primary one on. The filters are pretty well exposed and with the K&N panel filters I can't see how much of a difference it would be between the stinger and blackwing type filters. I am sure CAI is the way to go if you are really looking for a bump in performance but I want to leave my car in stock form.

be on the look out for water being captured in the 'stock' air boxes with the secondary cover removed.

That is just internet rumor LOL. K&N filters or similar (Holley, Fram Air Hog etc.) will outflow an OEM style paper filter every time, probably even when they're a little dirty...the only questions out there are whether or not they truly filter as well and/or allow some minute particles and if you'll really feel them once installed through.
I believe in those screen, gauze and oil type filters if you're looking for a simple, 'easy to swap out' set up but like Dennis said above it's not really worth it, just get a good cold air intake instead.

Well really not true. A clean paper will most of the time flow just as good as the K&N. But noticed I used clean. From the minute you start to use a paper filter it is losing flow capacity. A K&N at 25k will flow almost as good as it the day it was installed.
It is true that the K&N will let more particles in. But we are taking particles small than 10 microns. Such particles are pollen, very fine dusts such as cement dust etc. The chance of any particle this size causing damage is about nill in a N/A motor. I have had a few vehciles go over 300k running nothing but K&N filters as I have used this filter or similiar for the last 30 years.
As far as dyno improvement with just a K&N, you won't see it unless you compare say a 5k papaer filter to a 5k K&N. IMO the advantage is less maintance and more consistant performance.

only the 'stock' air boxes will have the problem. the stock design allows water to collect in the 'boxes' but the aftermarket units do not have a bottom, just an open filter.
