Dry air filter vs. oiled filter...


I'd like to hear some thoughts on oiled vs. dry filters. I've been running an AFE conical oiled filter for a couple of years and it seems to be ok. I clean/re-oil it two or three times a year. I run a pre filter over the top of it.
I have been thinking of going to a dry filter, although I can't come up with a good reason...

Oiled or dry air filter for diesel

Any reason to go with oiled over dry, or vice versa? Filtering, flow, maintenance, etc?

Oiled filters get plugged with dirt FAST, driving mainly county roads my dads 05 with an AFE stage 3 plugs pretty regular.

They way I see it

Dry= dusty roads/ farm use. How many farm tractors do you see with an oiled filter?
Oiled= City drivers that rarely see dirt.

Maybe your dad shouldn't follow so close...

I'd rather clean an oiled filter than rebuild an engine.

Actually many older tractors have oil bath filters and also a dust bowl. but i know what you mean and i agree with you.

i run a dry paper filter

i use dry filters, cause i feel that the oiled ones dry out with the turbo sucking so much air through it with the way some ppl drive these days. the dry ones are built to filter just like an oiled one imo. either one works good but like stated on dirt roads they clog faster cause the dust clings to them like its supposed to do. i clean my every couple months when driving it regularly just to keep it clean and its simple to stick in the sink and run some soap and water through it and then dry and go back to driving

Many farm tractors have a dirt separation system that removes 95% of the heavy dirt from the air before it gets to the primary filter element, then there is a secondary element inside that.

I have an A F E cone filter on my dodge and i don't put oil on it and it seems to work good. Just my 2 cents!

I wouldn't run anything that is designed to work better as dirt gets clogged in it...

The dryflow filters filter down to only a few micron in size... I'll stick with my dryflow.

so your using a reusable oiled filter without the filter oil? That doesnt sound healthy for the longevity of a motor. the small airways between the mesh material on a oiled filter is substantially larger than a paper filter. this is why the oil is so important to trap dust. Be careful my friend would hate to see you get excessive blow-by from such a simple thing.

were would i get a dry filter to replace my oiled s&b filter? id want it to fit the same inside the cold air box. Ive always run oiled but i know they dont trap as much dirt as they say. And a dry will filter better from the get go.

Doesn't seem to matter much with me if its oiled or not, I seem to end up rebuilding about every 2500 miles or so anyway!!!

Seems like every test I've ran, my Junker race truck makes more horsepower running without a filter. It made the least running a stock paper panel filter, middle running and oiled AFE, and most running without a filter.

That said, Swole, you must be into high performance and that's why you rebuild your engine every 2500 miles. For maximum performance, you can't beat an open turbo sucking pure atmosphere.

I guess when you window a block, the spray of oil from the open crank case could go right into a filterless turbo and that oil could turn into a nasty run-a-way..... as in light it on fire and Run Away!!!

There are times I wonder how bad it could hurt to run filter less.......then I pulled a small bird out of my filter.

I run a 5 year old K&N just because I change crap too much and its always laying around.

Might as well just put some lace panties over the turbo intake instead of a filter!

What is better oiled or dry air filter?

Generally, high-performance dry filters can catch up to 99% of the incoming contaminants due to the smaller micron size of the filter media, while oiled filters catch about 98% of what passes through – a minute difference, but a difference none-the-less.

Is it worth putting a cold air intake on a diesel?

If there's too little oxygen, it could result in increased fuel consumption. Cold air intakes are designed to provide the optimal air to fuel ratio, which can lead to horsepower gains and improved gas mileage. Since you're getting more out of your fuel, you're also likely to see a decrease in fuel expenses.

Does oiled air filter damage engine?

Oiled filters will damage your engine's MAF sensor. Dry filters are the only way to go. Dry filters let tons of dirt get through to damage your engine's pistons and rings.

Does a K&N filter make a difference on a diesel?

By eliminating some or all of these points of restriction with a K&N diesel air filter, or diesel air intake system, K&N Air Filters is able to improve diesel performance by increasing horsepower and torque output.
