Inefficient air filter

[2014 Ram]

guys, I changed my air filter today in my 2014 Ran 1500, after one year and 15k miles, and noticed only a very small area of the filter is actually being used..... doesn't look very efficient to me... just thought I'd share

I swapped my stock filter for a k&n a long time ago, so I can't comment on the stock ones

I had a K&N stock replacement, not much difference, air box design too restrictive. I just installed a Vararam Air Grabber, Wow what a difference!

That looks more like it is the part above the breather tube where it might have soaked up some blowby (oil and gas).

Looks like oil blow by to me.

Exactly my thoughts. There is no way that part of the filter is the only part that air passes through. Lol

That filter looks new. I'd leave it till it's black.

Did you know a dirty filter filters better than a new filter.
Dirt plugs the larger holes. Yes, the filter gets more restricted.
But as it gets dirtier the holes in the element get smaller therefore trapping smaller dirt particles.
You can change filters too often.
IMO.

Your theory is true if you're talking K&N.They have to be half plugged before they start doing a good job.Paper filters do the job right from the start.

Even paper filters clean better dirty. K&N, Fram, etc does not matter.

Time to replace your pcv valve.

Opinions are like assholes,everybody has one!
There's been a **** wagon load of studies done on K&N and they all come up with the same conclusion.They just don't do the job of filtering that an OEM paper filter can do right from day one.And that is when the K&N has been properly serviced which most of them probably aren't.

They have their place(racing application where the motors are built frequently)but not for everyday driving.I wouldn't have one in my 20 year old lawn mower.

As far as paper and K&N filtering better plugged you are right,but the paper is a better filter right from new.

You brought up K&N ********.
Were talking air filters in general. Not brands, makes or models.

Your pcv valve draws a suction from the crankcase. Your make air line draws fresh air from above your air filter into the valve cover. If your pcv system is not working correctly you can get excessive blowby through the make up air line.

Noob here, isn't it that that pcv line connected near TB, after not before the airfilter?

I do agree, paper filter will be more efficient from the start but also filter better with use...
This has been proven in home filtration systems as well...

K&N might flow better in the beginning but at a sacrifice of Filtration! I myself would rather have better filtration through out the life of the filter... Just Me and My LoL! Opinion!

I was lucky enough to find the best of both worlds...

He's got a 4th Gen. PCV dumps straight into the intake manifold just after the throttle body. Crankcase vent/make-up is piped to the OEM airbox pre-filter. Could be that is where some oil is coming from, but not a PCV thang per se.
