I'm using a 10 dollar Fram filter over a K&N I bought a while back. The K&N dropin has holes in it that are visible to the naked eye. Who wants great airflow if they're letting all kind of crap into the intake, etc.? Not I......
Who's using what kind of air filters.....i've been thinking about buying a K&N....but i just don't ever seem to get around to it...
I got lucky with my red 04 and managed to buy a Green performance filter. They seem to me to be much better quality than the K and N or AirHog. If you shop around a bit on the internet you should be able to get one pretty reasonably. Just Google "Green Performance" to get their website.
When I got the 06 I just swapped the filter into it. Then when we ran the 06 on the dyno the first run was with the Green filter. Just for fun we next did a run with the factory paper filter and it caused a loss of 10 RWHP. I couldn't believe that it would make that much difference. We did a backup run with some correction for temperature and still lost 3 RWHP. So I can tell you that a Green performance filter in the stock intake system is worth somewhere between 3 and 10 horsepower at the rear wheels.
Just make sure to keep your stock filter as you will need to put it in while you are letting your oiled filter dry after washing it. It is very important to follow the instruction of not blow-drying any air filter (due to possible damage), and it takes several days for them to air dry.

So what about that demo I saw on TV with the K&N and stock filter blowing the ping pong ***** up the tube? They went twice as high in the oiler filter tube. This was on Trucks, Spike channel. i think they would want to see what was better without any tomfoolery.
Using the cheap O'Reilly filters. $10-$11 and it was identical to the OEM filter i just pulled out...yellow paper element w/gray felt gasket.
Don't want to turn this into a K&N bash, but I started to question their use after I put a new one in my '95 GMC (round filter). I took the top of the air cleaner off a few months later and there were pools of oil in the bottom of the air cleaner. Imagine where this oil goes in an air box design like our trucks?
I have used K&Ns in two different trucks, and honestly think they each ran and sounded better with cheap paper filters. It's just an air filter, keep it simple. But sometimes we get caught up in marketing (I'm guilty) and hype. If someone made a $30 oil filter and touted it as the most revolutionary design ever, we would probably be all over it too.
I'm amazed at how so many companies take a simple part (windshield wipers, brake fluid, power steering fluid, etc.) fool us into the "more expensive is better" trap.
the stock filter can flow all the air the motor could ever desire
aftermarket filters do the same
the difference is how hard the motor has to work to get that air. the K&N and other aftermarket filters make it easier for the motor to breathe. this frees up some HP since there is less parasitic loss. I've always used the high flow setups. just change your oil at regular intervals. just because Ford says 5k, doesn't mean to do it.
now, if you live on a dirt road, stick with the OEM style filter. the amount of dust will lower your engines life
all that being said, I love my Volant. it helped with throttle response and the "seat of the pants" feeling says it worked...did it really?...I don't know
Throw a handful of dust/dirt at a paper filter and most of it falls off, throw the same handful at a oiled filter and see what sticks. Old time filters were oil bath, not much into the paper market. (If there was any).
