Interesting Reading about airfilters

For you guys running the CAI's and K&N airfilter's this link may be something you might want to read. ISO 5011 airfilter test report

Man thats alot of reading. My attention span is not that long.

Goodday,

Thanks for the link and all the information. The more I read about K&N the more I am glad that folks like you keep us up to date and filled with data. It seems that K&N is mostly snake-oil and hype that does not pan out and in fact seems to be pretty detrimental.

Ciao,
Falcon

Nice digging Old Navy. Pretty interesting info. Snake-oil indeed Falcon!

Hehehe I can relate to that, seems to be an age related thing with me. How about you?

In all fairness most ( not all so take it easy guys and gals lol ) mods aren't very good for the long term life of your engine. The K&N is a performance filter designed to allow more air flow. The GM filter is designed to save GM money on replacing engines before warranties are up. My feeling has always been "live for the moment" so the heck with long engine life, I want to go fast.

I've gone 85k+ miles with a K&N and had no problems. Did a top engine clean once or twice and felt good about the performance I had.

What I didn't see in the test is how much dirt over how much time is acceptable?

Realistically, I'm getting rid of any car I own well before 100k anyway. So yes, live for the moment.

I used to run K&N's in my jeep..trust me I DON"T want to read about them...I know exactly what I am doing to my motor :(

[Old Navy]

Yes for anyone not interested in long engine life and don't plan on have their cars for a long period and like living in the moment then this has nothing to do with you. I bet close to 70% of the owners here will be driving a different set of wheels before the cars are out of warranty so why should they care.

Myself I'm a diesel nut and I have always liked to drive a car or truck till they are worn out if they are something I really love to drive like this Magnum.

Funny this testing was obviously done by GM (Delco) and seems to be geared toward diesel engines. Wonder why the Delco Filter seems to be the best?? I agree with O N though, that most will have long gotten rid of their rides before the warranty is out. Personally, I think that fine dirt/dust that gets through the K and N makes for good lapping compound to properly clearance the engine, and generate more power, LOL, LOL.

to accomodate the other side though, the oh-58 delta recon helicopter was switched to k&n filters right before oif because of "moondust"i.e. the dust that is so fine its finer than baby powder.

it substantially cut down on the amount of engines replaced because of wear and tear or intake debris.

i also have a mitsu with 122k that i have run with a k&n cone for 120k of that. yesterday i drove it 400 miles from ft campbell to ft rucker with no probs. it has good compression and absolutly no carbon buildup. the mag is only at 21k with a drop in, so i cant comment on that.

i dont take away from the test, but from what i've seen, the K&n will do its job. thats just my experience

Thanks Old Navy. Some eye opening results in that test data. I always felt that the oil based filters like K&N allowed for a much greater chance of contaminant ingestion in the air flow. Seeing data like that and participating in the GAIFO tests make me so glad I kept the stock airbox.

Not age here. It's always been the attention span when it comes to reading.

The "moondust" will clog a standard because it will not penetrate the media, yet it's "soft" enough as to not cause sudden heavy wear as sand would if allowed into the turbine, so in that case yes it would beat the option of inflight clogged filters.

Not all car engines are as easly damaged by the difference in filtering quality of airfilters, just like not all engines sludge as easy some do, such as the difference in 3.5L & 2.7L Chrysler engines. Not everyone can drive in as clean as air as others drive in and that has effect also on the filtering. Also 150k miles is as far or further then most ever own a car or truck with a gas engine, however when you go to the diesel side you often see diesel cars & trucks being driven 10 to 20 years by same owner and the mileage going to 250k to 350k+ miles in that period of time. There are lots of diesel cars out there under 5 years old with 200k + miles on them, such as a friends '02 VW Golf diesel with 243k + miles this time last year while here for a visit and still going very strong. These people will want to do nothing to lower the life expectancy of the cars as a general rule, however there are those who own a diesel that still think in hotrod mode and not duribility mode. All they see is a 40 to 50 mpg car that they can hotrod like it was a hi-pro V6 or V8 engine.

Based on my own long term test, I'd have to say that K&N dose a pretty good job. My F150 Lightning pick-up truck has had the same K&N in it for 12 years, cleaned on average once every year, for 130K miles. Besides the K&N, I have run Mobile 1 10w-30, changing every 7000 miles, all its life so far. Compression is still outstanding, runs strong, valve guide seals are starting to indicate a little TLC is in order, but they were good to go for over 125K miles.

I'm no scientist, but pre-mature wear is not a problem in my little experiment. The truck is a daily driver, but lives a somewhat cushy life compared to most trucks, however it is used to tow bass boats and ATVs, now and then sees max payloads, made a few runs down the quarter mile, and even carried a few deer to the check station. It no doubt has seen more dirt roads, and is put under more stress than the average LX ever will. Oh yea, it gets 14 MPG in the city and 19 on the highway

Let me know how that stock filter is doing in ten years, we'll compare notes.
