Please don't subject your engine to a K&N Air Filter

As far as i am concerned any company that advertises more flow without increasing the surface area of the filter is going to have less filtration…. And anyone who uses compressed air to blow out their filters trying to “clean” them is basically giving them selfs a free k&n with all the micro tears the filter will have after

I used to run K&N on my dirt bikes years ago. They worked well until the 2000s or so. Then started seeing crap in the intakes. Not sure what changed but never again.

I had similar experience but with my wife's Impreza. Had an AEM dryflow panel filter in it. Checked the filter after about 10k miles and the entire intake tract was coated in very fine dust. Threw that thing away, cleaned everything and went back to a Wix. Never looked back.

why no mopar in the test...Funny thing about k&n is they only start working after they are dirty and look like they are clogged. I stopped using them when oil analysis always showed more silica with the k&n vs stock...

Wix=Mopar for the most part.

I just want a S&B so I can hear the turbo go wheeeeeee

K&N Madea sense for motorcycles in the 70s, 80s and 90s. But the stock filters on stock engines have improved alot.

Already knew k&n filtered the poorest.

Two questions worth asking, I think.

A: does a little better flowing filter help at all?
B: does a little more fine particles hurt much?

I’ve always been inclined to think the answer to A was no and B was eh, maybe but not worth it if the answer to A is no.

The best filter setup was the old chevys when you flipped the filter housing lid, you got nice pre warmed air to prevent thermal shock to the engine who needs cold air for performance lmao

Ahhh, the old hillbilly horsepower. Good for at least 15 at the rear wheels right!!

Not really, most vehicles come from the factory with a CAI. Power can be had with an intake and tuning but increasing the amount of air over a certain percentage without a tune isn't going to gain a load of power that one would notice.

My above post about the S&B wasn't serious. I don't care about turbo noise. S&B does make a good looking product but sadly I don't care about showing it off.

They were rhetorical questions but I agree.

Yep exactly what i was saying the original Hot air intake lmao

I had an AFE dry filter on my 2007 Cummins. It helped some on the power. What I noticed the most is it didn't smoke as much when I had the Smarty tuned up. I liked the Smarty but I always hated the smoke.

Real steel!!!! Not much plastic on that baby.

Can this be adapted to work on a Power Wagon? Asking for a friend

I usually run an AFE dry flow filter for the reason that they are washable and reusable. I NEVER blow the filters I only wash and air dry. I have found the cost of factory filters has risen substantially and they are requiring them to be changed much more frequently. If I get a few more HP then it’s a bonus. I am really enjoying how quiet and fast these trucks have become.
