Anyone install a K&N air intake on 99' E300

I was looking to get a stock K&N element. Or, go with a cold air intake type of element. They sell the pipe with a cone looking filter on ebay. Has anyone tried these? Are they a bad idea?

There has been many threads that say K&N oil can coat the $$$ MAF sensor and ruin it. The stock W210 air filter setup is fine for the OM606. If you were going to "superturbo" it an upgrade would be good.

K&N

There was a post some time ago with a link to a Ford diesel pick-up site .... wherein some members were able to do their own air-filter tests on machinery designed for that where one of them worked. They bought a selection of filters and went to work -- incl a K&N.

The K&N flowed more air than the rest of them -- but also let more dirt thru. I don't remember all the figures ........... but the the AC Delco filter let .7 gm of dirt thru ........... and the K&N let 7 gm thru. I pulled the K&N off my car, giving up what felt like a (very welcome) couple of horsepower in the process.

You're better off having it tuned from a place like Kleeman or Renntech to get some actual power...

k&n

I agree with the readers here. I had a k&n filter and it does flow better.
However I noticed a light film of oily dust collecting inside the air filter housing and inside the screen of the MAF sensor.......
It seems like a future problem......
Maybe a slight modification to the air filter housing to allow more air in using to stock filter would help.???

When I purchased my new air filter, once before I bought a Mann and this last time I bought a Bosch. MAn what a difference in air flow. Before I installed it I wanted to see how easily the air goes through the filter by inhaling some air with my lips to the filter element. WOW, that Bosch filter felt like there was nothing blocking my air passage, as the Mann I recall was definately more restrictive. Only the Bosch filter for me.

I don't think the stock housing and intake tract is restrictive, it's not like many domestic vehicles that pick up 11-14rwhp from a hacked air box or an open filter. This stuff is designed to be efficient with minimal (if any) power loss, it's pretty crazy really to me.

I put a stock K&N filter in mine and am very happy with it. As usual there are many factors with the K&N and also the "stock" paper filters. Proper cleaning and oiling has to be a major one of these. That, in itself, will determine what kind of filtering performance you get from a K&N. I personally think some of the so-called tests, which do not even mention this, could be slanted in any direction for the results you desire.

No filter is a cure-all or performance "upgrade" and opinions for brands will be argued till the automobile is no more. More importantly, proper and routine maintenance is the bigger factor.

One thing about a filter that you can reuse is the cost issue, a K&N, Mean Green, etc can pay for themselves pretty quick. OE filters aren't cheap.

In the air housing there appears to be sufficient space for a Prefilter or a foam wrap to catch more particles. I use one on the FIPK that's on my Z71, works quite well to keep larger matter from the filter.



I do have a question, on the size of the fine sand that enters... how large is this in terms of micron?

*Most* sotck air intakes flow enough for the engine. The main reason for such long and restrictive looking ducting on stock setups is to dampen the intake soundwaves. Pulling them off usually does little more than increase engine noise. Pull the u-tube off the turbo and run it for a few seconds, right away you will hear what the UFO over the turbo does.

These little sobs blow enough with the stock filter.

I wouldn't run a K&N these are not Mustangs MB put some money into good air flow with these cars.

With a turbo charged engine unless the air filter is really plugged the turbo will suck enough air through it.

Yup, they have to conform to federal driveby guidelines at WOT. Odd but true.
