Hi there, anyone know if there's a K&N air filter available for the V6 Atlas? It's typically the first thing I add to any new vehicle I get, but I can't find it listed?

How effective are air filters? I've never modded a car before aside from the small things like tinting, but something like the Atlas deserves more.

It can depend on the vehicle, but you can typically see a small increase in power output and gas mileage. I also like the fact that the K&N is washable / reusable, so you never have to buy another one or replace it.

More noticeable results would be found from a full system, but I don't know if we'll see that kind of support for the Atlas. The most important difference with an aftermarket filter is that they can last forever with proper maintenance.

I just installed the K&N in my Atlas, and I was shocked at what I saw on the stock filter. For some reason, in addition to the std paper filter, there was a large air-porous foam layer added on top of the paper part of the intake. I'll post the photo shortly, but it looked like batting/padding that you would find inside a couch pillow.

My friend and I had the same thought - it looked like the factory had left packing material on the filter when it was installed.

I put the drop in mine about a month ago when it was available. Run these in all my vehicles. Gives a little more engine noise through the intake and you can wash/re-use it...I do mine every 50K miles. The oil filter MAF issue is complete BS/urban legend. Been running them for years with not a single issue. Look at the testing videos K&N has on youtube...that oil isn't coming off. The slight drop in filtering efficiency vs. paper isn't enough to worry about.

^^^Sarcasm? Unlikely to restrict it at all...
No not at all. I guarantee it restricts air. Standard common physics. As simple as trying the breath through a pillow Vs breathing through a shirt, which one would I choose in order to keep free flowing air volume, the shirt.

This topper foam is nothing more than a filter wrapped with a pillow, or one would say, a sleeping bag.

Less obstructions = more air volume

There is no doubt that K&N are less restrictive (at the expense of a *little* filtration) but the issue is that that your engine is getting all the air it needs through the stock filter so allowing it to have more doesn't really do much b/c it doesn't need it. I mainly like K&N due to the lifetime aspect and the fact you get a little more sound.

I've used these on other vehicles. Did you notice better performance and/or better gas mileage after installing on your Atlas?

No. A little more noise at WOT acceleration is about all plus I have one filter for life. Any performance gains are v. small and would only be noticed/measured on a dyno if they are even there. MPG increase, no way and certainly not measurable if there.

Thanks for the info. I may end up going this route down the road. Definitely post back if you start noticing mpg increases etc.
