Just wanted to let everyone know than K&N now stocks their air filters for our RDX. Here is the direct link to the product information:
http://www.knfilters.com/search/prod...x?Prod=33-2382
I do not think they sell directly, but the filters are available at many places online and locally. I have always used these filters in my cars and always been pleased with the results.

please don't buy this guys, does alotta harm.

Dry flow or paper filter is the way to go. Go pick up a Wix Air Filter part number 49123 it has a very good rep.

What characteristic of an oiled gauze filter is harmful? I've only run them on practically every performance vehicle I've ever owned. K&N boasts that they will last 1 million miles, flow better than paper filters, and performance does not degrade when they get dirty.

What kind of harm are you talking about. I have been using K&N for nearly 20 years on every car I have owned, with no "air filter" related problems...
A great product IMHO.

Agreed; I've always used them myself. Care to explain further mau108?
thx

There have been lots of discussion on K&N filters. Basically they don't slow down when dirty because they don't stop dirt in the first place. The oils on the filter are harmful the engine. There were a lot of other arguments. In the end I have to say it changed my mind. I used to run K&N all the time. Not anymore. One other point raised was that the air the engine could suck in on its own was far less than the stock filter lets through. Therefore the conclusion was that the extra air the K&N filter let through did not really help. Search the third gen TL forum and you can find all the info.

Sounds like a lot of unsupported speculation to me.

I like foam filters, but I am not sure if they make one that is a "drop-in" element. I have a comptech icebox (different car) with a foam element, which works superb.

MAP sensors failing because of the oil, lack of filteration, apparently the longer the filter is not cleaned the better it does filtering lol because the dirt that accumulateds pretty much add to the filter.

I personally dislike it, if I were to go synthetic filters (reusable) AEM dryflow, easy to clean too.

Paper: WIX or OEM.

I will throw my two cents in here...

I used JR high flow filters and KN as well... both worked fine in my old 2003 SAAB 9-3 turbo. Until I tried ITG foam filter in my old BMW 2001 330i,... I didn't realize it initially but the foam filter looked a little over oiled... but I used it anyway, and it downright nearly stalled my bimmer when I ran it... After a few days of running it, the car was shaking and stalling... I immediately replaced it with the used stock filter (which I kept for such contingencies), and the car was fine after running for a few minutes...

Moral of the day is: These oiled filters work fine and well, but pay attention to the filter and see if the product comes appropriately oiled. Sometimes poor QC, leads to a product that may contain too much residual oil and damage the MAF.

Very few peple have the patience to clean, completely dry, and re-oil a K&N filter properly. Either you need two filters or about a day without the car.

Typically the filters are over-oiled, which causes the aforementioned problems.

Also K&N argues that their reusable filter is better for the environment, because 15 paper filters would be thrown away over the life of a K&N. But when the K&N is rinsed clean with a garden hose, where does the oily residue go? Into the local groundwater.
