Has anyone here had any problems with after market filters such as K&N, Green, etc.? Your input is greatly appreciated.

 

Have run K&N with no problem and Vrus filters with no problem.

 

No problem wth Greens..are you having a problem or trying to decide to swap out the OE ?

 

I have read that W210 E55s will tend to have problems with their MAS as a result of the oil on the K&N filter. As air is drawn in the oil is pulled in as well it then contaminates the Mass Airflow Sensor and causes rough running and power loss.

On the W211 E55Ks I have not heard or read of any problem but they have a MAP.

So your 55 K&N or Green, the latter being my choice
and your 430 I would stay with OEM.

 

I've been running K&Ns on both E55s with no issues, but I only put about 10K miles on each.

 

I run K&Ns no issues so far. The ones who get problems are usually the ones who over re-oil themselves.

 

K&N's for all my Benz's, no problems.

 

Lovin me some K&N's. 2nd set and no problems.

 

I Have abrand new set K&N W211 air filter for sale . $50 plus shipping , if you interest please let me know.Thanks

 

Good price...I've payed $200 for mine here

 

Can the charcoal filters be removed for long periods of time?
Where are they located?
By my questions you can tell I'm a newbie. Just trying to get in the 11 sec club.

 

Don't think 55's have charcoals do we guys?

 

Nope, only the 63's.

 

what do K & N fillters do by the way

 

They've been around for years on the motorcycle aftermarket&within the past 10yrs or so have become popular with cars as well.Basically,it's a re-useable filter that can be washed&cleaned&then put back into service.K&N hypes a "1,000,000 mile warranty" on them.
I got a price from my buddy from his store for $25 each,so what the hell I might as well put them in.

 

have put 100k+ miles on K&Ns for my M3, M5, and now E55. Always one of my 1st mods.
