Hi Tony,

The K&N is not a good filter, and especially bad on a diesel which has no throttle plate and is always WOT in the intake. I've run K&N filters myself for many years, but I've been reading the studies about how much additional dirt they let through compared to factory filters, and it's a bit scary.

Consider using the Amsoil EaA201 filter instead. It's also a reusable filter, plus it requires no special chemicals to clean:

I am very happy with this filter on our CRD.

I used K&N filter for many years and never had a failure because of it. I had it on 98 Durango for 190K and so far on the CRD for 44K. Neither use or blow oil from thier use and always run strong as a result. Cleaning is no special chemical for it is the same as Spray Nine, just use the K&N spary oil treatment after allowing the filter to air dry. I don't see how the Amsoil EaA201 filter is much different.

Any idea how much K&N cost? I'm looking to buy 5 at once for me and my KJ friends here in BCN ( we are all 2.5 CRD's ).

The amsoil is $38.10 which is very cheap. It's this one right?

Absolute Efficiency Air Filter
1 FILTER
EAA201-EA

Got any pics of the actual product?

Hold them both up to a light and then see if you can describe a difference.

Don't we have an Amsoil dealer as a member over here?

DUH, already found it in the vendors ally. Thanks!

The K&N filter for the CRD runs about $38 in the USA with free shipping.

I've ran K&N filters on all my cars over the last 10 years and haven't ever had an issue with a gummed up MAF or dirt. I would remove, clean and oil the filters every 4 (or so) oil changes though... and always let them dry over night. I recently purchased my first Amsoil air filter for my CRD and, honestly, it looks like a regular paper filter.. that's bright blue and orange.

I guess time will tell on how well it wears. I definately noticed a difference in spool-up after replacing a "generic" paper filter with the AmsOil one.

I run a K&N on my track car. They really flow a lot of air, and they keep out the bugs and sticks. But I would never consider running one on a vehicle I intend to put a lot of miles on -- there is too much evidence (oil analyses, and direct measurements) that show K&N type filters do not stop the fine particles that slowly wear an engine down. If you mosey on over to the Mercedes Shop forums you will find no one that recommends one, even on the "old mercedes diesels". Contrary to gassers, a diesel will not show a benefit from a slight decrease in intake resistance, either in power output or fuel mileage. Additionally, diesel engines will last longer under normal use, and it makes sense to me to keep out as much dirt as possible. Some of these old Mercedes run for 300k-400k miles before they need a rebuild. I would hope the little VM Motori can do the same.

Well, I'm on my way, 115k Km already

I'll go for the Amsoil if posible.

I stopped using K&N in everything but my old motorcycles after reading oil analysis of vehicles running them. Every one had elevated levels of silica (dirt) in the motor oil. May not manifest itself in anything terrible, but it certainly increases friction and wear on the engine.

For a strictly street vehicle, or a race vehicle, they are probably a good option. For a 4wd vehicle that sees any use off-road in dusty conditions, they are a really bad idea.

After cleaning, the K&N will be clean while the Amsoil EaA201 is still dirty. HMMMM cleaning with a vacumm cleaner not going to work, common sense will tell you that. The K&N can be cleaned up to a million miles as told but I never seen it done. Don't sound like that the Amsoil can't get wet, no problem with the K&N.

tonycrd · **Posted:** Wed Feb 20, 2008 3:16 pm

Ok let's say they are both good. Only one needs oil and the other doesn't.

Boy did I start something.

Just going to point out the obvious here: The reason the filter can be so easily cleaned is because its a very porous material. If you just used the material from a screen door it would clean even easier, but it wouldn't keep much out of the engine.

Personally I'm sticking with factory stock and I don't have an opinion. I just found it strange that the fact that the filter is so easily cleaned dosen't itself raise some red flags...

Factory stock or compatable filter works for me. Blow it
out with the air compressor real well. Don't come clean
replace it.
I did see my filter oily some time ago. Couldn't clean it.
Replaced it and got rid of the oil in the system. EHM
and SEGR protected tells the whole story.

X2. I have a hepa filter for my shop-vac that I use when I'm doing drywall or woodworking at home and man, it's a bugger to clean but I don't smell the tiniest bit of gypsum after using it. On the opposite end of the spectrum, the foam filter insert that is used for "wet vacuuming" will clean up with pure water but it suck any kinds of small particles right through. same applies with any other kind of filter.

If you're worried about airflow through the box, get a filter with more pleats (amsoil or comparable) and put a vacuum gauge (filterminder is it?) on the box to really see if you're getting unwarranted restriction.

Does anyone make a "clean-effects" electrostatic filter like the one on my furnace? It works great

If you hold the K&N up to a light you can literally see through it. Some of the holes are nearly as large as window screen mesh like Reflex compared it to. No matter how much air you can flow through it the real story is in the oil analysis which shows a much higher percentage of contaminants with the K&N. I'm not trying to pick a fight just pointing out a serious flaw in the filter. Everyone will have to make their own choice about what works in their vehicle.

tonycrd · **Posted:** Wed Feb 20, 2008 8:23 pm

Well, since I pay about $25 for a OEM filter it won't hurt to put in an Amsoil one. If it gets blocked I can always replace it at almost the same price as the mopar.

I believe that the filter your talking about has to be damaged. K&N filters are not supposed to be blow out with high pressure air hose. Clean with cleaner like spray nine, rinse with clear water and let air dry. The Amsoil filter can't get wet so can't be clean and rinsed so have to be replaced. I believe that it would only last maybe a little longer than stock paper but cost why more to justified it. Now if the Amsoil can be cleaned the same way and filters better, I'm for it but the K&N type filters down to 5 micro so I'm ok with it.

nursecosmo · **Posted:** Wed Feb 20, 2008 10:15 pm

You are right, most K&N dry type filters aren't usually just blown out with compressed air. 5 micron filtration is [b]TERRIBLE![b] 5 micron is equal to 1300 grit sand paper. See this table http://users.ameritech.net/knives/grits.htm . The reason that the EA filters are easy to clean is that all the dirt is on the surface. Here is a pretty good explanation of how they work http://youtube.com/watch?v=IvJradh0kSQ . In the end they work out to be cheaper over time and filter better. And no, I don't sell them but I do believe in them.

Ouch! Do you have a source for Wix filters where you are? Here in the states, the Wix for our Jeeps has more pleats (better breathing) and is cheaper ($10-15 bucks as I recall). The Mopar looks like a crappy Fram.
